JENCO TDS, Temperature Portable Meter 3020M

JENCO TDS, Temperature Portable Meter 3020M Simultaneous displays of conductivity, salinity or TDS with temperature measurements. 50 data set reviewable memory. Convenient one point calibration. Calibration data is stored in memory and ready for use on power up. Adjustable TDS coefficient, reference temperature and temperature coefficient. Uses one conductivity cell for conductivity, salinity and TDS measurements. Accepts 4-wire conductivity cell with K= 0.475 cell constant and 2-wire K= 0.1 cell constants for improved flexibility and accuracy. Automatic shutoff function ( 30 minutes of non-use) . Battery life over 1000 hours. IP65 waterproof. Low battery indicator. RoHS and CE compliant.
