Specifications

Mi180 measures 6 different parameters: pH, ORP, EC, TDS
(Total Dissolved Solids), percentage of NaCl and tempera-
ture in a variety of ranges.
pH calibration can be performed in 3 points selectable
between 7 memorized buffers, to provide a very accurate
calibration curve even when testing different samples, where
very wide differences in pH can be found.
The auto-ranging feature for EC and
TDS measurements automatically sets
the resolution suitable to the tested
sample. All measurements can be tem-
perature compensated at 20 or 25°C
and the compensation coefficient is
selectable by the user.
The automatic temperature compensa-
tion can also be disabled for measuring
the actual conductivity 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
port or USB.
