The Hanna Instruments HI98301 DiST 1 is a low-range, total dissolved solids (TDS) tester that measures up to 2000 ppm (mg/L)
Useful when measuring TDS in a variety of applications;
- water conditioning
- environmental monitoring
- education and general laboratory use
The DiST® 1 features a large multi-level LCD which displays both TDS and temperature readings simultaneously.
The TDS readings are displayed with a 1 ppm resolution and with an accuracy of ±2% full scale.
The TDS range of the HI98301 is from 0 to 2000 ppm.
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 1382 ppm 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 8minutes, 60minutes, or disabled.
To enter the setup mode the user presses a button located in the battery compartment.
Large Multi-Level LCD
The large LCD displays TDS, temperature, calibration tag, battery level and instability indicator.
Exposed Temperature Probe for fast response
An exposed temperature probe allows for an extremely fast and stable TDS measurement.
Simple Two-Button Operation
Only two buttons for meter operation.
One for on/off and one for calibration.
Slim, Ergonomic Design
With rounded edges and a case that is only 17mm (0.7”) thick, the HI98301 is thin and fits comfortably in the hand or pocket.
Graphite Sensor
Reduces polarization effects and does not oxidize resulting in a reliable and accurate reading.
Automatic Calibration
Automatic calibration at 1382 ppm (mg/L) with a single push of a button.
Stability Indicator
A clock tag stability indicator will disappear to alert the user when the reading is stable.
Automatic Shut-off
User-selectable time until meter shuts off to conserve battery life. Options are 8 min, 60 min or disabled.
Low Battery Indicator
Low battery indicator that is displayed when less than 10% battery life is remaining.
Battery % Level at Startup
At start-up, all the LCD segments are displayed for 1 second, then the percent indication of the remaining battery life is displayed.
Features:
- Slim, Ergonomic Design that fits comfortably in the hand or pocket.
- Waterproof casing designed to float if dropped in water.
- Graphite sensor reduces polarization effects and does not oxidize.
- Automatic calibration at 1382 ppm (mg/L) with a single push of a button.
