Accurate conductivity, salinity, TDS and temperature measurements.

CC-401 Conductivity salinity Waterproof meter.
CPC-401 pH conductivity salinity waterproof meter.
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.

CC-401 meter

Model  Description 
CC-401  Conductivity salinity Waterproof meter
CPC-401  pH conductivity salinity waterproof meter

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.
