High precision conductivity meter DDSJ-308A TDS/Salinity/temperature measurement

Introductions:

Accuracy grade: 1.0

Backlit LCD display

Power failure protection

Automatic temperature compensation and automatic calibration

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 sensor of 0.01cm-1 and sealed measuring reservoir, it can test high purity water.
8. It is equipped with DJS-1C conductance sensor (platinum black) and T-818-B-6 temperature sensor
