Hanna HI 98312 - EC/TDS/Temp Tester

EC Tester Hanna HI 98312 – Simultaneous display of conductivity and temperature

The EC tester Hanna HI 98312 is a precise digital measuring tool designed to display conductivity (TDS) and temperature in real time. Particularly suitable for hydroponics, aquaculture, or any solution culture system, it allows monitoring of salt concentration to avoid nutrient overdosing.

Clear reading and automatic compensation

The device features a two-level digital display, readable even in low light conditions. Thanks to its integrated sensor, measurements are automatically adjusted based on the ambient temperature, ensuring reliable results at all times.

Simplified calibration and smart functions

The HI 98312 offers one-point automatic calibration. It is also equipped with the BEPS (Battery Error Prevention System) which prevents any false reading due to a low battery. The auto-shutdown function extends battery life by turning off the device after a period of inactivity.

Robust design and replaceable probe

The tester's casing is made of molded PVC, resistant to moisture. The HI73311 probe is easily replaceable and covered by a 6-month warranty. The unit is lightweight and compact, making it an ideal tool to carry in the field or in a greenhouse.
