1.Several kinds of pH buffers can be chosen for calibration. Furthermore, the buffer solution can be prepared by users.

2.The instrument can recognize five types of buffers automatically.

3.It has many functions such as automatic and manual temperature compensation, self-calibration and self-calculation of electrode percentage theoretical slope.

4.The data can be stored, deleted, printed and viewed, and the quantity of measuring data can be maximized to 200 sets.

5.It has standard RS-232 and USB interface. To match with data collecting software, it can be communicated with computer.

6.It is equipped with E-201-D pH combined electrode and T-820C temperature electrode
