Are used for highly accurate conductivity, salinity, TDS and temperature measurements.

CPC-401 additionally measures pH and ORP (mV).

Two kinds of power sources 9V battery or 9V power adapter enable work in the field and long-lasting measurements in the laboratory.

The whole measuring range enables measurements both of ultra pure water and salinity.

Calibration by introducing the constant K in range 0.01 ÷ 19.999 or in buffer solution.

Storing of 3 const. K of the Cells which cover whole range and 3 pH electrodes characteristics (CPC).

Wide range of  a coefficient  0 ÷ 10% / °C.

• Counting the salinity on the basis of real characteristics, what greatly increases the accuracy.

• Possibility of counting the TDS by introducing the TDS coefficient in range 0.2 ÷ 1.0.

• The characteristic features of pH function in CPC-401 identical like in CP-401 pH meter.

• Automatic or manual Temperature Compensation.

• Possibility of electric admittance measurement of tree scions (after purchasing special sensor)

• Both models have internal clock with date.

• Internal datalogger enables storing of 200 measurements taken as single or series with time, temperature and date.

• RS-232 output for connecting with a PC by or with a standard printer by special interface.
