DiST® 3 Waterproof EC Tester HI98303 (0-2000 ¦ÌS/cm)
| Previous | 4 / 17 | Next |
The Hanna Instruments HI98303 DiST 3 is a low-range electrolytic conductivity (EC) tester than can measure up to 2000 µS/cm making it ideal to monitor a variety of water quality applications including drinking water, water conditioning, irrigation water, and environmental monitoring. The DiST 3 is a rugged and reliable pocket-sized tester for use in the lab or field. This modern looking meter is only 0.7' thick and extremely ergonomic, fitting comfortably in your hand. This tester keeps things simple with a two-button operation; one for ON/OFF, the other for calibration.
- Large Multi-level LCD
- Exposed Temperature Probe for Fast Response
- Simple Two-Button Operation

Details
The DiST 3 features a large multi-level LCD which displays both electrolytic conductivity (EC) and temperature readings simultaneously. The EC readings are displayed with a 1 µS/cm resolution and with an accuracy of ±2% full scale. The conductivity range of the HI98303 is from 0 to 2000 µS/cm. An exposed temperature sensor allows for rapid automatic temperature compensated conductivity measurements. Temperature can be set to display in ¡æ or ¨H. 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 1413 µS/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.
