12 Myron L Instruments
Instruments & Test Equipment
Myron L Instruments, DS and pDS Meters Conductivity, TDS and pH Instruments
Myron L Company has two proven ways to measure such impurities. DS Meters provide fast, accurate,
on-the-spot measurement of total dissolved solids (TDS) or conductivity. pDS Meters test conductivity
or TDS, plus pH. Readings from their highly stable circuitry help prevent equipment damage, assure
product quality and verify in-line instrumentation in a wide range of applications and press the rubber
protected button. ppm/TDS is immediately indicated on the color-coded scale.
RE-10
532T1
EP11-PH
MODEL EP
The most versatile of all DS Meters, this instrument is capable of testing both ultra pure and ocean
water — and everything in between! It has five conductivity ranges for easy readability. The most
sensitive range includes resistivity equivalents, making it ideal for DI water systems. .5, 5, 50, 500,
5000 Micromhos, 2 – 30 Megohms
EP
DS Conductivity/Resistivity Meter: 0-0.5, 5, 50, 500, 5000 µM/µS; 2-30 MΩ
MODEL EP-10
With its four micromho ranges, this instrument is ideal for most water treatment applications. Its low
range will accurately test boiler condensate; with the RE-10 Range Extender, it can check process
solutions up to 100,000 micromhos.
EP-10
DS Conductivity Meter: 0-10, 100, 1000, 10,000 µM/µS
RE-10
Range Extender
MODEL 532T1
A popular model for many years, this instrument offers three very useful ppm ranges. Like other three
range and single range models, it features a unique electronic Internal Standard for easy and fast field
calibration and range doubling.
532T1
DS TDS Meter: 0-50, 500, 5000 ppm
MODEL EP11/PH
A popular, pDS model features four conductivity ranges and a 2 – 12 pH range 0 – 10, 100, 1000,
10,000 micromhos/microsiemens; 2 – 12pH.
EP11-pH
pDS pH/Conductivity Meter: 0-10, 100, 1000, 10,000 µM/µS; 2-12 pH
TechPro II™
TECHPRO II
The TechPro II is handheld, lightweight and simple
to operate. Measuring conductivity, TDS, pH and
temperature, the highly stable circuitry delivers
the accurate readings needed to assure product
quality, prevent equipment damage or verify in-line
instrumentation in a wide range of applications.
The TPH1 is designed with an internal pH sensor to
prevent breakage and prolong the sensor’s useful life.
The rugged, waterproof case on both models protects
the electronics of the instrument and fits comfortably
in your hand. This model also features auto shut-off to
prolong battery life.

Calibration Standards
The conductivity Standard Solutions and pH Buffers listed below are used for factory calibration.
Regular use of these solutions is recommended to ensure specified instrument accuracy. Frequency of
conductivity recalibration depends upon use, but once every month should be sufficient for an instrument
used daily. pH models, depending upon use, should be recalibrated with pH 7 Buffer every 1-2 weeks, and
checked with pH 4 and/or 10 Buffers at similar intervals. pH Sensor Storage Solution is recommended for
keeping the pH sensor wet. Myron L® solutions are available in quart/1 ltr., gallon/3,8 ltr. and 2 oz./59 ml
plastic bottles, ready to use. (Custom value standards only offered in gallon/3,8 ltr. size bottles.)
