pHSJ-5

Characteristic:

1.To measure potential、pH and temperature value;

2. Novel touching LCD screen;

3.To select one or more PH buffer solutions to calibrate the meter(provide ten buffer solutions; one point、two point and multi-point calibration(max/mum five point calibration) function;

4.RS-232 interface which can be connected with Model TP-16 printer to print out measuring results or be connected with computer to communicate with outside;

5.Protection from electricity cutting off. The stored data and parameters will be kept even if unusual electricity cutting off happens;

6.Measuring results can be stored, deleted, viewed、communicated and printed. It can store up to 200 different data.
