The TDS-2683 dual-function digital water quality tester combines pH and TDS detection into one compact pen, saving space and cost compared to purchasing two separate measuring tools. Fitted with high-precision sensitive probes and built-in automatic temperature compensation, it blocks temperature-caused reading errors and delivers consistent, accurate data for various water samples.

It features a clear LCD display with intuitive data readout, alongside user-friendly functions: data hold for easy record-taking, auto power-off to conserve battery power, and low-battery alert to remind you of timely replacement. The lightweight pocket-sized design allows you to carry it anywhere for instant spot checks. Pre-calibrated at the factory, it supports simple manual recalibration to keep long-term testing precision.

Made of wear-resistant ABS material with corrosion-proof electrodes, this tester suits daily drinking water testing, aquarium maintenance, swimming pool care and hydroponic cultivation. It is an economical essential tool for household users, aquarists, hydroponic farmers and small water treatment shops to monitor water quality conveniently.
