Model:PHSJ-4A laboratory pH meter
Dot matrix LCD, Chinese operation interface
Can make automatic and manual temperature compensation, automatic calibration,
automatic calculation of electrode percentage slope
The measuring result can be stored, deleted, viewed and printed. The max. storage
volume is 50 sets of measuring data
Customers can select five kinds of pH buffer solutions to make one-point or
two-point automatic calibration within （0~60）°C
The instrument is equipped with RS-232 interface, which can connect TP-16 printer,
can communicate with computer if using REX DC1.0 Software of Data Acquisition.
Can measure pH value of hyperppure water, pure water and boiler water by adjusting
equal potential point and using special electrode
Power off protection function.
