Detailed description

Used for pH, mV (redox potential) and temperature measurements.

Characteristic features:

Large easy to read LCD display enables simultaneous readout of the measuring function and temperature value.
Waterproof housing (IP-66) enables work in difficult conditions.
Small size and low weight make working in the field easier.
Two kinds of power source, battery or optional power adapter, enable working in the field or long lasting work in laboratory.
Calibration of the pH electrode: 1, 2 or 3 points.
Automatic buffer detection 4.00; 7.00; 9.00 pH. (optionally 4.00; 7.00; 10.00 pH).
Automatic temperature compensation.
Depending on the kind of connected pH electrode may be used for measurements of clean water, waste water, meat, cheese, pastes, soil etc.
Readout of the electrode's slope and offset.
Possibility of automatic calculation of the redox potential result, received with the chloride/silver electrode, to the hydrogen electrode.
Wide range of the temperature measurement.
Easy-in-use.
Memory of 50 results.
Equipped with separate stainless steel temperature sensor (Pt-1000B).
Powered by 9V battery or power adapter (12 V / 100 mA) option.
Long-lasting work on 1 battery.
Automatic switch off function to protect the battery.
24 months of warranty for the meter.

IJ44A pH electrode

The standard set includes CT2B-121 temperature sensor with Pt-1000B resistor, EPS-1 pH electrode for measurements in clean water. It should not be used in other types of liquid. Measurements in liquids with sediments should be made with use of IJ-44A pH electrode, which enables measurements in various samples of both clean and contaminated liquids and semi-solids. 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.
