Pronto EC On-line Meter with LCD and Alarm - HI983307

The Pronto EC Meter HI983307 is a water resistant conductivity meter designed specifically for the continuous monitoring of EC. With a user-selectable setpoint and visual LED alarm system, you can now measure with peace of mind. The HI983307 is supplied with a probe that compensates for temperature variations automatically and requires little maintenance.

  • User-selectable setpoint and visual LED alarm
  • Automatic temperature compensation
  • Water-resistant housing


Engineered to withstand the aggressive environments in agricultural and hydroponic applications, the HI983307 is a simple way to measure EC. Hang the meter above the sample for continuous measurement The unit runs without interruption on 12V DC power supply. The built-in, visual alarm activates when any measured value is outside the hysteresis range. This exclusive feature ensures maximum system efficiency with minimum investment. The meter has a splash-resistant housing has an IP54 rating and features a large integrated LCD screen for that can be easily seen from a distance with accuracy up to 9.99 mS/cm.

The meter is supplied with a HI7632 two-pole, amperometric EC probe for panel mounted mini controllers that measures in the high range (mS/cm and ppt). This probe uses a built-in temperature sensor for automatic temperature compensation and has a ½” male NPT threaded connection for insertion mounting. The HI7632 probe provides a rapid response and high accuracy EC measurements.

Features at-a-glance:

Water resistant housing

  • The meter housing is rated IP54 meaning it has a high level of protection against particles and a fair amount of protection against water

One-point calibration

  • Calibrate with 5.00 mS/cm EC solutions using a screwdriver

Automatic Temperature Compensation (ATC)

  • Samples automatically compensated for temperature variations

User selectable setpoint and visual LED alarm

  • Meter will activate when EC value is outside hysteresis range
