Auto-Ranging ATC Conductivity/TDS/Temp/NaCl Meter

The Hanna 50-HI9835 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, 50-HI9835 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.

50-HI9835 is supplied complete with 50-HI76309 Conductivity/TDS probe with 3.3' (1 m) screened cable, AA size Alkaline Batteries (4 pcs) and instruction manual in a rugged carrying case.
