DDSJ-308A (dot matrix display) conductivity meterConductivity meter

DDSJ-308A laboratory conductivity meter adopts single chip microprocessor technology to design theinstrument, water resistivity, conductivity, total dissolved solids has accurate measurement of watersolution (TDS), salinity (NaCl standard) and temperature function.

The main feature of the instrument is:

1, using a single chip microprocessor technology,automatic calibration, measurement range automaticconversion, the water solution (including generalelectrolyte solution and pure water) automatic temperature compensation of measurement, data processing accuracy.

2, and access to measurement data storage function,can store 100 sets of data.

3, with power-off protection function, parameter and storage of data will not be lost after the power has been set instrument.

4, with the conversion coefficient calibration constant of electrode, calibration of TDS and conductivityfunctions.

5, a printer interface, can print the currentmeasurement data and historical data has been stored.

6, with clock function.

7, the use of dot matrix liquid crystal display, Chineseoperation interface, visual and clear display.
