Waterproof Multi-Parameter Meter

Hanna Instruments' waterproof multi-parameter instruments measure pH, conductivity, total dissolved solids and temperature in one meter using a single probe.

The models are available, HI991300 measures low range conductivity and TDS and HI991301 measures high range conductivity and TDS. Both instruments provide full-scale pH readings and temperature readings.

Features include automatic calibration and temperature compensation, selectable TDS conversion factor, adjustable conductivity temperature co-efficient and battery error prevention system.

All readings are displayed on the dual level LCD, so the user can read pH and temperature or conductivity/TDS and temperature simultaneously. The LCD also has a reading stability indicator to assist the user to make the most accurate measurements.

Battery strength is measured and displayed as a percentage each time the unit is switched on.

The waterproof, ergonomic casing with wrist-strap enables ease of use. The unit is supplied with probe, hard carry case, battery and instructions.
