Hanna HI 9835

HI 9835 Waterproof, Autoranging, EC/TDS/NaCl/ºC Meter

Professional Extensive conductivity and TDS/EC range with the resolution automatically selected by the meter without pressing any key. Both conductivity (or TDS or NaCl) and temperature are displayed at at the same time.
User Friendly Large LCD with helpful graphic symbols and low battery warning. User replaceable probe. Easy calibration procedure with memorized values.
Design & Construction Rugged lightweight ABS material, large tactile rubber keys , PVC probe for best field protection, stable on workbenches, lab desktops or slippery surfaces.
Just One Probe HI 76309 measures any kind of sample from dionized water to brine with Automatic Temperature Compensation without requiring recalibration.

The Hanna HI 9835 can measure conductivity, total dissolved solids, NaCl, and temperature, all with one probe. The temperature of all conductivity and TDS measurements is automatically or manually compensated for by the meter's ATC circuitry. The temperature coefficient is user selectable from 0.00 to 6.00 %/°C (for EC and TDS only) and the TDS factor can be set from 0.40 to 0.80.

The meter is constructed with a waterproof, rugged housing which allows the versatility required for both laboratory and field use. Moreover, HI 9835 is equipped with a large LCD that helps the user through operation and calibration with large comprehensive symbols. Besides displaying the measurements, the LCD simultaneously displays the temperature. The display gives a low battery warning and switches itself off after 5 minutes of non-use to save the batteries.

HI 9835 is supplied complete with HI 76309 Conductivity/TDS probe with 3.3' (1 m) screened cable, AA size Alkaline Batteries (4 pcs) and instruction manual in a rugged carrying case.
