RT-202 Digital pH Meter – Portable Water Quality Tester for Aquarium, Pond & Pool

The RT-202 Digital pH Meter is a fast and reliable device for testing the pH level of water in aquariums, ponds, swimming pools, hydroponics systems, and laboratories. Unlike traditional drop-type test kits, this digital meter provides quick and accurate results on an easy-to-read LCD display, eliminating guesswork with color strips.

With a measuring range of 0.0–14.0 pH, a resolution of 0.1 pH, and an accuracy of ±0.2 pH (±0.1 pH at 20°C), this portable meter ensures consistent and precise results. The unit is user-friendly — just dip the probe in the water, and the reading appears in seconds.

The RT-202 comes with a clear plastic storage case, calibration screwdriver, and user guide, making it convenient for field and home use. Its auto-hold and auto-off functions extend battery life, and the reset-to-zero function ensures accuracy with every test.
