# Thinking about buying an Iontophoresis unit? Take the time to compare!

**All the manufacturers of Iontophoresis machines have different technical data, how can I make an informed decision?**

In order to make a well informed comparison between machines from different manufacturers you must be aware of, and understand the “ ICF “ – the Iontophoresis compare factor. Otherwise it could be that your chosen Iontophoresis device does not have any impacts against Hyperhidrosis.

The basic formula for this factor is an easy one, it is simply :

**Voltage x Current = Ionto Factor**

This could lead you to conclude that you should just compare the potential power output – in other words, how much current a Iontophoresis unit can deliver. At first glance this is quite simple but, if you look further, there are some other factors besides just the one mentioned above and they must also be included in the calculation in order to have a true comparison.

The Ionto Factor by itself is a too simplistic specification, because for your calculation it is also of utmost importance to know at which resistance the Volt and Current were measured. You must also consider if there is a pulse width to be calculated, and finally you need to know if these measured values are “ mean “ or “top “ values.

What is a mean value?

A current with a wave form otherwise known as Pulsed Current can be measured as a “top“ value, this refers to how high the current the current reaches its maximum point – in the example this is sixty Volts. Given as an mean value in the following example with a pulsed width of fifty percent, the mean value of fifty percent @ sixty Volts and fifty percent @ zero Volts is only thirty!!!

So you must keep in mind that :

**Ionto Factor @ body resistance @ mean pulse rate = ICF - the Iontophoresis Compare Factor.**

As mentioned above, be aware of the fact that a continuous electric current that flows in one direction only is referred to as DC or Direct Current, it has a oscillation of one hundred percent and is a mean rate- when the rate does not precisely appear on the display screen of the device, then the values shown are “ imaginary “ values.

To accurately make a distinction between the devices you must be able to make your calculations with the values that the machine reveals to you on the display screen. Does it disclose maximum values, mean values or simply “ imaginary “ values that the manufacturer would like you to believe the device can dispense?

For example, it is very difficult to believe a manufacturer when he advertises a device that runs on a puny battery and wants you to believe that this device is a high power Iontophoresis unit! From where does the device get the current?

From a one point two volt battery? From two or four batteries? Even with a sequence of eight batteries running at 1,2 Volts, you would still only have nine point six volts!!!

In a nutshell :

Voltage (in V) x Current (in mA ) @ body resistance ( in Ohms /1000) @ pulse rate with mean value = ICF

Iontophoresis Compare Factor.

__The Hidrex PSP100 has proven beyond any doubt that it can constantly deliver these rates: ( at a mean value )__

Sixty V x thirty mA @ two kilo Ohm – this means that the Hidrex PSP1000 has a ICF of three thousand six hundred “Hidrex units “ ( sixty *thirty *two) in direct current mode and it reveals mean values. A device with the highest level of technical development that has the maximum power allowed by the German medical law, the Hidrex PSP 1000 is a Iontophoresis machine with the highest standards and is in use in clinics worldwide!

Furthermore, the Idromed 5PS can also unequivocally yield the same numbers : ( at mean rate ) seventy two V x twenty five mA @ two kilo Ohm giving the Idromed 5PS an ICF of three thousand six hundred “Hidrex Units “ as well ( seventy five*twenty five *two ), and in addition also shows you the mean values. This is up to date, modern technology and provides the maximum power that the European medical code permits!

We are offering the Hidrex PSP 1000 and the Idromed 5 PS. Machines with maximum values that set the benchmark of excellence and safety when comparing them to similar devices.

When the PULSE RATE is reduced, you get ICF Factors of :

- ninety percent = three thousand two hundred and forty ( for Idromed : with a fixed pulsed width of ninety percent it’s the same as the Idromed 5PS or PC ).
- eighty percent = two thousand eight hundred and eighty
- seventy percent = two thousand five hundred and twenty
- sixty percent = two thousand one hundred and sixty
- at a fifty percent pulse rate we have an ICF of maximum one thousand eight hundred which means that at total power this is fifty percent as effective as when you would use it at one hundred percent ( run at DC ).

If you are looking at devices with an Ionto factor at even more reduced Ohms, this must also be calculated.

Let’s say that the machine you are looking at has forty Volts at thirty mA at zero point eight kilo Ohm with DC - if these are real numbers and not just “imaginary numbers “.

The formula for the ICF would be forty x thity x zero point eight x one hundred percent = nine hundred and sixty ICF.

By comparing the ICF of the Hidrex to the ICF of the devices of our competitors, we can see in the previous case, that the Hidrex has an ICF of three thousand sox hundred, while the other machine has an ICF of nine hundred and sixty. This means that the HIDREX PSP 1000 at the uppermost calibration, with equal body resistance has three point seventy five more power. A significant and very important difference!

In our many years of experience we have heard of no one that could endure the maximum intensity of the Hidrex PSP 1000 in DC drive. However, we have heard of many people that could tolerate a ninety percent pulse rate at full power.

Do we claim this to be THE WORLDS’ MOST POWERFUL IONTOPHORESIS MACHINE? No. We prefer to present the HIDREX as the forerunner in potent Iontophoresis technology and that according to EU Medical law, to produce more power than the Hidrex does would be illegal. If you would like to convince yourself, compare the values of the HIDREX PSP1000 against those of any other machine on the market today, we encourage you to use a multimeter to measure for yourself the voltage and the mA that the other machines can deliver!

How to get maximum results from Iontophoresis with a minimum of treatment time

What exactly are the major differences between Iontophoresis machines?

Before Buying a Iontophoresis unit or exchanging an old machine for a new one you should ask these questions:

1. Does the machine run on Volts or Current? this is a substantial difference, because your body reacts to a change in volts much differently than to a current change.

2. Where does the Current come from, battery or mains? A machine powered with batteries has no built in double redundancy safety system. It does not need such a system, because a battery driven device is only able to transmit a very weak flow. Trying to manipulate the flow with a unit powered by batteries to attain an oscillating DC is not possible, because you would be immediately hindered by the relatively feeble current that batteries provide.

3. Can the unit deliver sufficient Voltage? At a certain Voltage range, how the body experiences the current is more agreeable. This bandwidth lies between fifty an seventy Volts. This is relevant only for high powered Iontophoresis application and can not be valid for weak currents.

4. How long are the electrodes and the Iontophoresis machines designed to last? Both Idromed and Hidrex are powered by Volts. Both function in ideal bandwidths, both have a constant oscillating current ( PC ) (Hidrex is adjustable between fifty percent and ninety percent in ten percent increments and Idromed has ninety percent ). Both are robustly built to last a lifetime.

**Measuring Current**

There are also deviations as to how current is measured. The gauge for Hidrex is two kilo Ohms and it will provide up to sixty Volts at thirty mA at this resistance. This is the bodys' normal resistance to sweating hands and to the tap water that is used to expedite the current flow through the towels or distance grids to the skin.

For someone with a body resistance of higher than two kilo Ohms, ( for our example let’s double it to four kilo Ohms ) at this resistance the machine attains the utmost of sixty Volts at fifteen mA. Suppose, as in our example, that thirty mA needs to be delivered, then the voltage would need to be increased to one hundred and twenty Volts for the given body resistance to get the same mA to!!! This is totally unacceptable, unreasonable and unfortunately in many cases, fatal. The mains network in the USA runs on one hundred and ten Volts. This makes it obvious that no one should want to even try and tolerate more voltage than is allowed by the EU Medical Law.

The safer and more reasonable approach is to not let the body resistance surpass two kilo Ohms. From time to time this can become a problem when the skin becomes dry and loses it’s moisture ( when there is less or when the sweating has stopped ), there is a dramatic increase in body resistance. To help solve this problem the Current Care Lotion has evolved for use after the Iontophoresis treatments. Because of it’s high Urea and Zinc content it restores humidity and nurtures delicate skin. While other skin creams can hinder success, Current Care has been proven to support Iontophoresis therapy. Because it does not contain artificial fragrance, colors or preservatives and all of the ingredients are not likely to cause an allergic reaction, Current Care can also be used by people suffering from Psoriasis.

We highly recommend drinking lots and lots of water to achieve and maintain low body resistance.

If you are drinking enough water and your body resistance is still too high, you can try cleaning the electrodes more often. If you can notice that they are deeply scored ( often a problem with aluminum electrodes ), you should maybe consider ordering new stainless steel electrodes.

If you’ve adhered to all of the previous recommendations and your body resistance is still too high, you should examine your eating habits. Another factor that increases body resistance is ingesting a lot of citrus fruit.

If your body resistance is two kilo Ohm s, IDROMED and Hidrex can both put out an Iontofactor of exactly one thousand eight hundred.

When the body resistance is sub two kilo Ohms, Idromed and Hidrex impede the use of higher Iontofactors than one thousand eight hundred ( sixty Volt at thirty mA for Hidrex, and seventy two Volts at twenty five mA for Idromed.
