The Waterproof ExStik II pH/Conductivity Meter measures 5 parameters including conductivity, TDS, salinity, pH, and temperature using one electrode. It has 9 units of measure including pH, uS/cm, mS/cm, ppm, ppt, mg/L, g/L, °C and °F. An analog bargraph indicates trends. Internal memory saves up to 25 labeled readings. It has an adjustable conductivity to TDS ratio from 0.4 to 1.0; 0.5 fixed salinity ratio. RENEW feature alerts user when electrode needs replacement. Auto power off and low battery indicator. Waterproof to IP57.

This Kit includes EC500, 84 uS/cm, 1414 uS/cm, 12880 uS/c, calibration standards, pH buffer pouches (1 each of 4, 7, 10 pH plus rinse solution), weighted base, 3 sample cups with caps and case.
