Functions:
It can measure pH,mV(ORP) and temperature.
◆ The instrument is equipped with large LCD Touch Screen and English operation system for easy use.
◆ Several kinds of pH buffer solution can be chosen for instrument calibration. Furthermore, the buffer solution can be prepared by users.
◆ The instrument can recognize five types of buffer solution automatically.
◆ It has many functions such as automatic and manual temperature compensation, self-calibration and self-calculation of electrode percentage theoretical slope.
◆ The data can be stored, deleted, printed and viewed, and the quantity of measuring data can be maximized to 200 sets.
◆ It has standard RS-232 and USB interface. To match with data collecting software, it can be communicated with computer.
◆ It is equipped with E-201-D pH combined electrode and T-820C temperature electrode.
