PH / EC / TDS - 3 IN 1 PROBE - 0.01 PH RESOLUTION - Hanna Instruments Portable pH/EC/TDS Meter is a handheld unit that measures pH, EC, TDS and temperature with a single probe for agricultural, greenhouse and hydroponic use.

It features a large LCD that shows pH, EC, TDS or temperature with on screen guidance.

The meter provides 0.1 pH resolution with +/-0.1 pH accuracy and displays EC and TDS in 0.01 mS/cm and 1 ppm increments with 2 percent full scale accuracy.

A variable EC to TDS conversion factor adjusts automatically from 0.56 to 0.78 ppm per µS/cm, and all readings are temperature compensated using a fixed 2 percent per °C coefficient.

The HI1285-51 probe integrates pH, EC, TDS and temperature measurement and includes amplification to limit electrical noise.

Calibration is manual at pH 7.01 and at either 1.41 mS/cm or 1500 ppm, and the display includes a battery life indicator.
