Hanna Conductivity/TDS & Temp Monitor – HI 993302

The wall mountable Hanna Conductivity/TDS & Temp Monitor meter has a large, dual-level, backlit LCD and displays instantaneous readings of both EC/TDS and temperature, even from a distance.

Waterproof and chemically resistant, HI 993302 have been designed to meet the Grower’s need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. At startup, HI 993302 perform a self-check to assure proper working condition. These powerful instruments also feature a stability indicator and hold feature that prompt the user when to freeze the display and take the reading.

Calibration and temperature compensation is automatic, while the EC/TDS conversion factor and temperature coefficient factor (ß) are user adjustable for application specific measurements. Choose your EC/TDS indicator according to the proper EC/TDS ranges for your application:

  • HI 993302: EC – 0.00 to 20.00 mS/cm; TDS – 0.00 to 10,000 ppm (TDS 10 ppt = 10,000 ppm )

Supplied with:-

  • HI 7630 conductivity probe
  • HI 70030 (12.88 mS/cm) calibration solution sachet, 20 mL
  • 12 Vdc power adapter and instructions

Please note that continuous meters, will need their probes cleaned regularly to make sure that they don’t get fouled up, its best to clean them at least once a month (minimum) for half an hour in Hanna HI-7061 General Purpose cleaning solution. To clean them we sell a cleaning solution that you pop the probe in and leave. It might seem like a pain, but the more often you clean your probe, the longer the life expectancy and the more accurate readings you get. Probe life can vary six months with no cleaning, up to one to two years if they are cleaned and maintained regularly.
