Functions:
It can measure pH,mV(ORP) and temperature.
LCD display, English operation system
Automatic and manual temperature compensation, self-calibration, and self-calculation of electrode percentage theoretical slope
Five types of pH buffer solution can be chosen to conduct automatic calibration (one point or two points)
Test results can be stored, deleted, viewed and printed. The amount of data can reach the maximum of 200 sets.
It has RS-232 interface, and it can be connected to TP-16 printer. Also, the interface can be used to connect data collecting software and computer.
It can be used to measure pH value of ultrapure water, pure water and boiling water by adjusting equipotential point and choosing specific electrode.
It is equipped with E-201-C pH combined electrode and T-818-B-6 temperature electrode.
