Product Instructions

HI 981410 EC tester has been specifically designed to address the needs of operators in hydroponics, greenhouses and nurseries.

Calibration is easy and completely automatic. Simply press and hold the on/off button for a few seconds and the meter will request the appropriate calibration solution. Place the probe in the solution and wait until it is calibrated. No extra buttons to push or dials to turn!
