single range ds meters
operating instructions
description
this manual describes your Myron L Ds meter, tells you
how to use it, and how to keep it working accurately for
many years.
Your model 512 single range Ds Meter is a compact
instrument which operates on the principal of electrical
conductivity. it will quickly determine the conductivity or
ppm/total Dissolved solids of almost any solution. Models
512M2, 512M3, 512M4, 512M5 and 512M10 have dials
calibrated in micromhos (µmhos), which is equivalent to
the metric microsiemens (µs). Models 512t2, 512t3,
512t4, 512t5 and 512t10 convert the conductivity
directly into parts per million (ppm) of total Dissolved
solids.
all are 3.4” x 4.5” x 4.0” (85 x 129 x 126mm) and weigh
less than one pound (0.45kg). Ds Meters are completely
self-contained. the built-in cell is automatically
temperature compensated from 50º to 160ºF (10º to
71ºc). they are powered by a 9 volt battery good for at
least 2000 tests, or one year shelf life.

By using an re-10 range extender (see
accessories), the maximum range of most meters 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.
