ExStik Conductivity TDS Salinity Tester

This ExStik Conductivity TDS Salinity Tester is a waterproof, high accuracy, multi-range sensor that measures four parameters simultaneously: Conductivity, TDS, Salinity, and Temperature. An auto-ranging feature allows the meter to offer three (3) ranges of measurement from pure water to salinity solution to waste, boiler and cooling water using the same conductivity cell. The internal memory stores up to 25 labeled readings. Durable in a wet environment, the ExStik meets the IP57 standard.

Measurements are reported on an easy-to-read LCD (2000 count) display. An analog bar graph tracks sample trends. The electronic components self-calibrate on startup. Data Hold, Auto Power Off, and low battery indicators allow the user to monitor device status.

Using an adjustable Conductivity to TDS ratio factor from 0.4 to 1.0, the ExStik calculates the TDS value. Meter verification/calibration is only required once a month during normal use. The ExStik allows for a 1-, 2-, or 3-point calibration.

Includes four CR2032 lithium-ion batteries; replacement 3039-51.
