Instrumentation: 4P and 6P Myron L Ultrameter

ultrameterTo be able to easily measure water conditions is fundamental to selecting the right method of treatment. At the right is the handiest meter we know of the Myron-L Ultrameter II. The Model 4P unit measures Conductivity, Resistivity and TDS(Total Dissolved Solids). What is unique is that it provides all these measures at the same time on the same water sample so you can easily switch between the different units of dissolved water impurities.

The model 6P also measures pH and ORP. It requires the use of buffers to keep the unit in calibration. The unit is rugged – I keep a model 4P backseat of my car so it is available at all times.

We use these units all the time to monitor how our water systems are doing as we visit different clients. You get quick feedback on the quality of the water sample so you can make adjustments in treatment on the spot.

One of the important measures of water quality is the amount of dissolved minerals in the water which is called Total Dissolved Solids(TDS). TDS is typically measured by devices which quantify how the water sample conducts an electrical current.


The most important thing to remember is that the all the units measure the same thing and are all done by electrical current conduction. The measuring instrument?s internal electronics make the conversions to the unit of measurement shown on the dial.

Conductivity is measured in MS/cm2 which is Micro-Siemens per Square Centimeter. This measurement is used more commonly for Untreated City Water and often in Cooling Tower and Boiler Water Conductivity.

Resistivity is measured in Meg-Ohm/cm2 which is Million Ohms per Square Centimeter. This measurement is used commonly in Treated Deionized or RO/DI Water Systems for High Purity Applications. The reason that Resistivity is used is that Conductivity at High Purity results in low readings which are difficult to discern.

TDS. measured in Mg/L, translates to dissolved Milligrams per Liter of solution. To make sense out of all the different measurement units, we try to convert them all to this unit. Here is a Conversion Chart which shows Conductivity, Resistivity and Total Dissolved Solids(TDS).

If you are interested in measuring water using this unit, please decide whether you want the 4P – Conductivity, TDS and Resistivity or the 6P which adds PH and ORP to the dissolved solids measurements of the 4P. Please note your preferences on our Quote Form and we’ll send you pricing.
