Description
The Hanna HI98301 DiST 1 is a compact, waterproof TDS tester built for quick spot checks in the lab, greenhouse or field. Covering a 0-2000 ppm range, it suits water conditioning, environmental monitoring, education and general laboratory work wherever a simple, affordable meter is all that is needed.
Key Features of the Hanna HI98301
- Large multi-level LCD that shows TDS and temperature at the same time
- Exposed temperature probe for fast, automatically compensated readings
- Simple two-button operation: one for on/off, one for calibration
- Graphite sensor that resists oxidation and reduces polarization for more repeatable readings
- One-point automatic calibration at 1382 ppm with a single button press
- Stability and calibration tag indicators built into the display
- Selectable auto shut-off after 8 or 60 minutes, or disabled entirely
- Low battery warning plus a battery percentage readout at start-up

Who Should Buy the Hanna HI98301
Hobbyists checking drinking water or aquarium quality, students and instructors in school labs, and technicians who need a lightweight backup meter all get good use out of the DiST 1. Its low price and pocket-sized body make it an easy addition to a toolkit alongside larger multiparameter instruments.
How to Calibrate and Use It
Press the dedicated calibration button and dip the probe into the 1382 ppm calibration solution supplied with the meter. Once the reading stabilizes, the DiST 1 automatically recognizes and stores the value, so no manual adjustment is required. For everyday testing, rinse the probe, dip it into the sample, and read the TDS and temperature together on the LCD.
Maintenance and Care
Because the graphite sensor resists oxidation, it needs little upkeep beyond an occasional rinse with clean water. Replace the CR2032 battery once the low battery indicator appears, and store the meter in its protective sleeve when it is not in use to keep the probe safe from knocks.
Frequently Asked Questions
Can the HI98301 double as a thermometer? Yes, the exposed probe reads temperature alongside TDS, so you get both values on the same screen.
Does it need frequent calibration? Most users only need to recalibrate occasionally, since the graphite sensor holds its accuracy well between checks.
Is it suitable for aquariums or pools? Yes, the 0-2000 ppm range comfortably covers typical aquarium, pool and drinking water testing.

Each Hanna HI98301 comes with a CR2032 battery already installed, four sachets of 1382 ppm calibration solution, a protective storage sleeve, an instruction manual and a quality certificate, so it is ready to use as soon as it arrives. Choosing this meter from Water Filter Oman also means genuine Hanna Instruments stock, straightforward warranty support, and quick delivery across Muscat and the wider Sultanate, which matters if you rely on the tester for daily checks rather than occasional use.
If your work needs conductivity and a wider TDS range alongside temperature, the Hanna HI98312 is a good step up from the DiST 1, but for everyday checks under 2000 ppm the HI98301 remains one of the simplest and most affordable ways to keep an eye on water quality at home, in the greenhouse, or on a job site.
Whichever way you plan to use it, a few seconds of rinsing and calibrating before each session is usually all the preparation the HI98301 needs to deliver a trustworthy reading. That reliability, combined with its low price, is why this little tester remains a popular choice across Oman.
