Name: SL1-DDSJ-308A conductometer
Brand: Midwest Group

Model:

Can measure electrical conductivity, TDS salinity and temperature.
Dot matrix LCD, full Chinese operation interface, simple and convenient operation.
Automatic temperature compensation, automatic calibration, automatic switchover of measuring range, adjustable solution coefficient and power-off protection.

Can store, delete, consult and print test results. The Max. memory is 50 sets of measuring data. On-line printing and memory printing are available.
Calibration function, which can calibrate electrode constant or TDS conversion coefficient.
The adoption of titanium alloy electrode with 0.01cm-1 electrolytic cell constant and seal measuring groove can meet the measurement of highly pure water.
RS-232 interface, can be connected with TP-16 printer, and communicate with computer by selecting REX dc1.0 data acquisition software.
