Product Description

DDBJ-350 portable Conductivity Meters

Functions:
1.Special backlit LCD display
2.It can measure conductivity, TDS, salinity and temperature.
3.It functions as automatic temperature compensation and automatic calibration.
4.It provides power failure protection and automatic power-off functions.
5.It has calibration function. The user can calibratesensor coefficient and TDS conversion coefficient.
6.Measuring results can be stored, deleted and viewed. Up to 100 sets of test data can be stored.
