HI 9835 combines four important parameters you need for measuring conductivity. Now you can sample Electro-Conductivity (EC), Total Dissolved Solids (TDS), sodium chloride (NaCl) and temperature simultaneously.

Hanna 4-ring probe design innovation allows for greater stability over a broader measuring range. This probe is equipped with an embedded temperature sensor.

You can choose between automatic and manual temperature compensations to match your operating requirements. In addition, you can also select from a range of TDS factors from 0.40 to 0.80 and a range of temperature coefficients 0.00 to 6.00% for greater consistency and reproducibility. The housing is completely waterproof and built to survive the harsh conditions of field use. For extended time studies, this meter can be connected to a 12 Vdc power supply (optional).
