Description
The Hanna HI98312 EC/TDS/Temperature Tester is a rugged, waterproof handheld meter built for professionals who need fast, dependable water quality checks. Designed to float rather than sink if it is accidentally dropped, this tester combines three essential readings, electrical conductivity, total dissolved solids and temperature, into one easy-to-use device suited to laboratories, farms and industrial sites across Oman.
Key Features of the Hanna HI98312
- Dual EC/TDS scales that switch automatically between 0-9999 µS/cm and 0-9999 ppm
- Automatic Temperature Compensation (ATC) keeps readings accurate no matter how warm or cool the sample is
- HOLD function freezes the display so a reading can be recorded without rushing
- Battery Error Prevention System (BEPS) warns you before a weak battery can distort results
- Factory calibrated and ready to use straight out of the box
- Rugged IP67 housing built to handle heat, dust and accidental submersion
Technical Specifications
- EC range: 0-9999 µS/cm
- TDS range: 0-9999 ppm

Where the Hanna HI98312 Fits In
Desalination plants use this tester to confirm TDS levels meet drinking water standards, hydroponic growers rely on it to balance nutrient solutions, and construction teams check mixing water quality to help prevent corrosion in concrete. Because the Hanna HI98312 handles conductivity, TDS and temperature in a single unit, technicians can move between sites without carrying separate meters.

Who Should Buy the Hanna HI98312
Facility managers who currently juggle separate EC, TDS and temperature devices, water treatment technicians who need quick spot checks between lab visits, and growers who monitor nutrient solutions daily are the most common buyers of this meter in Oman. Its rugged build and simple one-hand operation also make it a practical backup device for larger multiparameter systems.
How to Get Accurate Readings
Rinse the probe with clean water before each test, then dip it into the sample and swirl gently until the reading stabilizes. Press HOLD to lock the value on the display, note the result, and rinse the probe again before moving to the next sample. Keeping the protective cap on when the meter is not in use helps the sensor stay calibrated for longer.
Maintenance and Care
Because the Hanna HI98312 is factory calibrated, most users only need to check calibration occasionally against a standard reference solution. Replace the battery as soon as the BEPS indicator appears so measurements stay reliable, and store the tester in a dry place away from direct sunlight when it is not in use.
Frequently Asked Questions
Can this meter test seawater or brine? Yes, the 0-9999 microsiemens range covers most brackish and seawater samples, though very high salinity water may need dilution first.
Does it need separate calibration solutions for EC and TDS? No, one calibration solution is normally enough because the meter derives TDS from the same conductivity reading.
Is it suitable for continuous monitoring? The HI98312 is built as a portable spot-check meter rather than a fixed inline sensor, so it suits routine sampling rather than round-the-clock logging.
