Best Portable TDS meter

HoneForest TDS meter

HoneForest portable TDS meters come with the best quality and the most reasonable price. The premium quality titanium alloy always ensures high accuracy.

One added feature of the TDS meters is the reliable Automatic Temperature Compensation (ATC). It provides that the reading is always accurate, regardless of the temperature.

The upgraded backlit LCD has made reading more accessible. Also, the auto-lock function makes it more user-friendly. Taking the readings is also simplified with simple steps like turning on the TDS meter, stirring the water gently, and auto-locking on the LCD in seconds.

The auto-shutdown feature that turns the TDS meter after 02 minutes due to the inactivity saves power.

The multipurpose portable TDS tester can offer a variety of applications. They include testing drinking water purity, monitoring reverse osmosis (RO)/DI system performance, the maintenance purpose of aquariums, testing nutrients in hydroponics, and maintaining pools and spas.


  • Quicker Reading
  • Easy to use
  • Lightweight
  • Money Back Warranty up to 03 years


  • No added calibration feature or a solution

VIVOSUN pH & TDS Meter Combo

VIVOSUN pH & TDS Meter Combo has been designed to offer more than just checking the TDS of water. The VIVOSUN pH & TDS Meter Combo includes a pH meter, which allows the user to check the acidity or alkalinity of the soil, and a TDS meter that includes EC and TDS. Also, the kit has temperature functions.

The TDS meter has been made more portable due to its calibration-non-required feature. The manufacturer has assured us that it is not needed to be calibrated as the device provides accurate readings continuously.

The VIVOSUN pH & TDS Meter Combo kit also includes a protective case, which makes it easy to transport and store. Additionally, there is a battery included, making it ready to use right after taking out of the box.

According to hundreds of user reviews, the devices are used in Water Purification Applications, Aquaculture, Hydroponic, Pool & Spa, Colloidal Silver, and Water Treatment, like all kinds of water-implemented surroundings.

If you are a person who admires portability as a high concern, the VIVOSUN pH & TDS Meter Combo will be your match.

Hanna DiST 1 Waterproof TDS Tester (0-2000 ppm) – HI98301

The HI98301 DiST 1 is the highest reliable and accurate TDS meter. It has several valuable features, such as the sizeable multi-level LCD that simultaneously displays TDS and temperature readings. Hanna claims that the device displays readings with an accuracy of ±2% full scale. The TDS range of the meter is from 0 to 2000 ppm.

The exposed temperature sensor allows the users to get fast and stable temperature-compensated TDS measurements.

The TDS meter uses graphite electrodes to reduce polarization effects and better repeatability in measurements. Calibration has been made easy with a dedicated calibration button. All it takes is less than 10 seconds, and the meter automatically will store the calibration value.

Among the portable TDS devices mentioned, the Hanna Three-Range Portable TDS Meter has the highest accuracy. But, we must remind you that you must pay a higher price for that as it costs $60.

Compared to reliable TDS meters you must dump after a few readings, the DiST 1 Waterproof TDS Tester (0-2000 ppm) – HI98301 offers you a continuous 03 years of functioning without any error.
