Detailed description

Accurate and easy in use laboratory meter used for pH, mV (redox potential) and temperature measurements.

Characteristic features:

Large easy to read LCD display
Simultaneous readout of the measured function and temperature value.
Calibration of the pH electrode: 1 ÷ 3 points 4.00, 7.00, 9.00 or optionally 4.00, 7.00, 10.00 pH.
Automatic buffer detection.
Automatic temperature compensation.
Depending on the kind of applied pH electrode may be used for measurements of clean water, waste water, meat, cheese, pastes, soil etc.
Possibility to check the electrode condition (buffer and slope).
Memory of 50 results.
Wide temperature measurement range.
24 months of warranty for the meter.

The standard set includes CT2B-121 temperature probe with Pt-1000B resistor and EPS-1 pH electrode for measurements in clean water. It should not be used in other types of liquids. Measurements in liquids with sediments should be made with use of IJ-44A pH electrode. Its unusual construction ( ”intermediate junction”) protects the real junction (diaphragma) of the electrode against clogging, ensures stable measurements in these types of liquids or semi-liquid masses, in which other electrodes stop working quickly. When properly handled and maintained, the electrode's lifetime is longer than the standard electrodes.
