  Details:
Functions
1.LCD backlit display and English operation interface

2.It can measure conductivity, TDS, salinity and temperature.

3.It functions as automatic temperature compensation, auto-calibration, measuring range switch and power failure protection.

4.Measuring results can be stored, deleted, viewed and printed. Up to 200 sets of measuring data can be stored. There are two print modes can be chosen which are real-time printing and storage printing.

5.It can set sensor constant and TDS conversion coefficient.

6.It has RS-232 port and can be connected with TP-16 printer. If matched with data collecting software, it can be communicated with PC.

7.If matched with the titanium alloy sencor of 0.01cm-1 and sealed measuring reservoir, it can test high purity water.

8.It is equipped with DJS-1C conductancesensor(platinum black) and T-818-B-6 temperaturesensor.
