pH/Conductivity Instrumentation

Accuracy • Reliability • Simplicity

DESCRIPTION

This manual describes your Myron L pDS meter , tells you how to

use it, and how to keep it working accurately for many years.

Myron L pDS Meters are compact, light-weight, self-contained
conductivity/pH meters. They contain a built-in conductivity cell with
a replaceable pH sensor. Models EP11/pH and M6/pH have dials
calibrated in micromhos (equivalent to the metric microsiemens) and
in pH units. They will quickly determine the conductivity and pH of
almost any solution.

Both are 3.4" x 4.5" x 4.0" (85 x 129 x 126mm) and weigh less
than one pound (0.45 kg). pDS Meters are completely self-contained.
The built-in conductivity cell is automatically temperature
compensated from 50° to 160°F (10° to 71°C). They are powered by
two 9 volt transistor batteries good for at least 2000 tests, or one
year shelf life.

MODEL CONDUCTIVITY RANGES pH RANGE

EP11/pH 0-10, 0-100, 0-1000,

0-10,000 micromhos (µmhos) 2-12 pH

M6/pH 0-5000 micromhos (µmhos) 2-12 pH
ACCURACY: (Both Models)

Conductivity: ±2% of full scale

pH: ±0.2 pH units

REPEATABILITY: (Both Models) ±1%

By using an RE-10 Range Extender (seeACCESSORIES), the
maximum conductivity range of each meter may be increased ten
times.

The pictures in this manual show the major operating parts of
your Myron L DS Meter. Handle your DS Meter and identify these
parts to become familiar with it.

IMPORTANT: The pH sensor in your pDS Meter has a limited life
much like a battery. Sensor longevity is af fected both by the types of
solution tested and care given your meter. pH sensors are user
replaceable. See MAINTENANCE for additional information.
