Handheld Meters
for analytical measurement variables
Type 202710/20 – Handheld Meter for pH, Redox, and rH
Type 202710/30 – Handheld Meter for Conductivity (CR), Specific Electrical Resistivity, TDS, and Salinity
Brief description
Product Group 202710 instruments are battery-powered hand-held meters for measurments in
laboratories, industrial and wastewater plants, in aquaria or fish farms, etc.
The instruments feature a memory for the MIN/MAX value, and a “Hold” function. To increase
the operational life of the battery, the instrument can be switched off automatically within the
range from 1 minute to 2 hours; continuous measurements can also be performed. The
instruments are operated from a membrane keypad.
The 202710/20 version is an instrument for measuring pH, redox potential (ORP) and
temperature. It features both manual and automatic temperature compensation of the
measurement. The Pt100 temperature probe necessary for this purpose is available as an
option. A standard combination electrode can be connected via a BNC socket. The
combination electrode is adjusted through a 2-point calibration.
The 202710/30 version is an instrument for measuring electrolytic conductivity and
temperature. The pre-assembled conductivity cell incorporates graphite electrodes and has a
cell constant of 1.0 1/cm. The temperature probe for automatic temperature compensation is
integrated in the measuring cell. The hand-held meter always indicates the conductivity, which
is compensated for 25°C. Thanks to the automatic range selection, the measurement is always
displayed within the optimum range. This function can also be switched off.
