- Measures five parameters including Conductivity, TDS, Salinity, pH, and Temperature using one electrode. - Units of measure: pH, µS, mS, ppm, ppt, mg/L, °C, °F - Memory stores up to 25 labeled readings - Adjustable Conductivity to TDS ratio - Auto power off and low battery indicator - Includes buffer tablets: 7.0; 4.0; 10.0 - Use separate pH and conductivity meters if sample conductivity is less than 200 uS. False high conductivity readings may result using a combined pH/Conductivity/TDS Tracer below 200 uS. Refer to other electronic instruments for separate pH and conductivity/TDS meters.
