EC/TDS

Mi170 measures 4 different parameters - EC, TDS (Total
Dissolved Solids), percentage of NaCl and temperature in
a variety of ranges.
The auto-ranging feature for EC and TDS measurements
automatically sets the resolution suitable to the
tested sample. All measurements
can be temperature compensated
at 20 or 25°C and the compensa-
tion coefficient is selectable by
the user.
The automatic temperature com-
pensation can also be disabled
for measuring the actual conduc-
tivity value. The stability indicator
on the LCD ensures accuracy.
Conductivity readings are performed
with the 4-ring probe supplied with the
meter. The GLP feature allows users to
store and recall data on system status.
PC compatible through an RS232 or USB port.

Autoranging EC/TDS/NaCl/Temperature Laboratory Bench Meter
More accurate readings with the
4-RING MA814DB/1 EC/TDS/NaCl
and Temperature probe!
Conductivity readings are performed
by applying an alternate current
to the 4-ring probe which
creates a variable volt-
age depending on
the conductivity.
