pH meter with printer.

CP-502 Laboratory pH-meter with printer set with pH electrode.
Laboratory meters in benchtop housing, powered with 9V power adapter. Accurately measure: pH,
Redox (mV) and temperature. Depending on the kind of used electrode they may be used for clean water,
sewage, soil measurements etc.
The CP-502 meters have built in thermal printer. Calibration: 1 ÷ 5 points. Automatic buffer detection,
heir value may be changed by the user. Automatic correction of the temperature influence on sample
solution (NIST) value.

pH meter

Model  Description 
CP-502  Laboratory pH-meter with printer set with pH electrode.

Automatic checking of the condition of electrode’s membrane.
Both models have an internal clock with date.
Internal datalogger for up to 200 sets of results collected in series or single with temperature
time and date.
The results and calibration data are stored in non-volatile memory.
RS-232 output for connecting with a PC and Centronics for standard printer.
24 months warranty for the meter, 12 for the electrodes.
