Prices include GST. Not all items are in stock. Call 03 9769 0666 to confirm.

The HI99301 is a rugged, portable EC/TDS and temperature meter housed in a case rated for IP67 conditions. It is supplied with a two-ting conductivity probe to allow for high range EC measurements from 0.00 to 20.00 mS/cm and TDS measurements from 0.00 to 10.00 ppt. All readings are adjusted with Automatic Temperature Compensation (ATC) and users are able to adjust the temperature correction coefficient and TDS factor for accurately compensated measurements.

  • One-point Automatic Calibration
  • Adjustable TDS factor
  • Automatic Temperature Compensation

The portable, waterproof HI99301 EC/TDS and temperature meter is suitable for use in applications as diverse as wastewater treatment, reverse osmosis, and HVAC. It measures high range conductivity in mS/cm and TDS in ppt. The HI763063 EC/TDS probe is a twO-ring sensor that resists clogging and is easy to clean. The probe also features a built-in temperature sensor to allow for Automatic Temperature Compensation from 0 to 60℃ (32 to 140℉).

The meter easily fits in the palm of your hand and the bottom probe connection ensures the electrode cable doesn’t get in the way. The large, multi-level LCD displays the primary reading, temperature, and calibration guides simultaneously. Symbols and messages on the LCD indicate meter status and guides users through operations.

Features at-a-glance

Two-Ring Probe – The HI763063 is a two-pole probe that comes with the HI99301, offering an accurate solution for high range EC and TDS readings. The probe features a built-in temperature probe to allow for temperature compensated readings.

Two Measurement Modes – HI99301 offers two measurement modes: EC and TDS. Users can easily switch between measurement modes with a simple press of the MODE button. EC measurements range from 0.00 to 20.00 mS/cm; TDS measurements range from 0.00 to 10.00 ppt.

Adjustable TDS Factor – The TDS value in aqueous solutions is directly proportional to conductivity. The ratio between the two parameters depends on the solution being measured. The HI99301 has an adjustable TDS factor from 0.45 to 1.00 with 0.01 intervals, allowing users to choose the conversion factor that is the most appropriate for their particular solution.

Automatic Temperature Compensation – Since temperature has such a dramatic effect on conductivity and TDS readings, having a meter that offers temperature compensated readings is invaluable. The probe of the HI99301 features a built-in temperature sensor that automatically accounts for the effects of temperature in the range of 0 to 60℃ (32 to 140℉).

Adjustable Temperature Compensation Coefficient – The temperature compensation coefficient, also known as β, is adjustable from 0.0 to 2.4%/℃ with 0.1% intervals; this factor corrects the reading a set percentage % for each degree Celsius change in the sample.

Automatic Calibration – The HI99301 can be automatically calibrated at one point in a standard EC or TDS solution. A 12.88 mS/cm standard is used for EC calibration, which will automatically calibrate TDS readings. However, if the meter is in TDS mode and set to 0.5 conversion factor, a direct calibration in 6.44 ppt TDS calibration solution can be used.

Battery Error Prevention System (BEPS) – The Battery Error Prevention System detects when the batteries become too weak to ensure reliable measurements.

Instability Indicator – The HI99301 displays a clock tag that will disappear when a reading has achieved stability.
