Pure Water Meter growing-media Moderate application of IR lightMeasures conductivity (in a wide range of 0. 1 S to 199 mS), salinity, TDS (total dissolved solids), and temperature. Determine water conditions in boilers, coolers, water conditioning, waste water, photography, environmental testing, aquariums, labs, industrial and quality control. The large LCD shows conductivity, TDS or salinity in large digits with time, date, and temperature (in C or F) shown simultaneously on the lower display. Scroll 99 data
