DDSJ-308A Conductivity Meter

Features
1. This conductivity meter usesLCD backlit display and can measure conductivity, TDS, salinity andtemperature.
2. The functionsof automatic temperature compensation, auto-calibration, measuring range switchand power failure protection can be supported.
3. Measuring results canbe stored, deleted, viewed and printed. Up to 200 sets of measuring data can bestored. Two print modes can be chosen which are real-time printing and storageprinting.
4. This conductivitymeter can set electrode constant and TDS conversion coefficient.
5. It has RS-232interface and can be connected with TP-16 printer. If matched with datacollecting software, it can communicate with the computer.
6. If matched with thetitanium alloy sensor of 0.01cm-1and sealed measuringcell, it can test ultrapure water.
