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

 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;

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

 Measuring results can be stored, deleted, viewedcommunicated and printed. It can store up to 200 different data.
