Hanna HI-98301 DiST 1 Pocket TDS Tester

The Hanna HI-98301 Pocket TDS Tester is a compact, robust instrument designed for measuring Total Dissolved Solids (TDS) in water, with a range from 0 up to 1999 ppm (mg/L). It is ideal for both laboratory and onsite applications, giving you fast and reliable readings.

 

Thanks to its Automatic Temperature Compensation (ATC), measurements remain accurate even when sample temperatures vary. The device uses a graphite electrode, which resists oxidation and gives long-term stability. Calibration is simple — just one calibration point with the included standard solution (HI 70032) ensures that readings stay accurate over time.

 

Its slim and ergonomic body is waterproof, making it well suited for field technicians, water treatment plants, aquaculture, agriculture, environmental monitoring, and general water quality analysis.
