TDS Tester (ppt) DiST®2 - HI98302
The Hanna Instruments HI98302 DiST® 2 is a high-range total dissolved solids tester than can measure up to 10.00 ppt (g/L). The DiST® 2 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
The DiST® 2 features a large multi-level LCD which displays both TDS and temperature readings simultaneously. The TDS readings are displayed with a 0.01 ppt (g/L) resolution and with an accuracy of ±2% full scale. The TDS range of the HI98302 is from 0.00 to 10.00 ppt (g/L). An exposed temperature sensor allows for rapid automatic temperature compensated TDS 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.
TDS 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 6.44 ppt 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.
The large LCD displays TDS, temperature, calibration tag, battery level and instability indicator.
