DiST®4 Waterproof EC Tester (0.00-20.00 mS/cm)

The DiST^® 4 features a large multi-level LCD which displays both conductivity and temperature readings simultaneously. The EC readings are displayed with a 0.01 mS/cm resolution and with an accuracy of ±2% full scale. The EC range of the HI98304 is from 0.00 to 20.00 mS/cm. An exposed temperature sensor allows for rapid automatic temperature compensated conductivity measurements. Temperature can be set to display in ℃ or ℉. The LCD screen has stability and calibration tag indicators. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.

Conductivity readings are performed by an amperometric graphite electrode that resists oxidation, providing better repeatability in measurements. The use of graphite also reduces the polarization effect common with amperometric testers that use two stainless steel pins.

Calibration is performed by pressing the dedicated calibration button. Once in calibration mode submerge the probe in 12.88 mS/cm calibration standard. When the standard value is recognized and stability reached, the meter will automatically accept and store the calibration value.

Setup options include automatic shut-off timing and temperature unit displayed. Automatic shut-off options are to turn the meter off after 8 minutes, 60 minutes, or disabled. To enter the setup mode the user presses a button located in the battery compartment.

Features and Benefits

Slim, Ergonomic Design

• With rounded edges and a case that is only 17 mm (0.7”) thick, the HI98304 is thin and fits comfortably in the hand or pocket.

Large Multi-level LCD

• The LCD is 29 mm (1.125”) x 20 mm (0.81”) allowing the user to easily read both EC and temperature simultaneously.

Two-button Operation

• One for ON/OFF, the other for calibration.

Exposed Temperature Sensor

• Exposed temperature sensor allows for quick Automatic Temperature Compensated measurements. Temperature can be displayed in either ^oC or ^oF.

Graphite Sensor

• Reduces polarization effects and does not oxidize resulting in a reliable and accurate reading.
