Simplified Digital pH & TDS Meters Water Quality Test Kit for Hydroponic, Aquarium, Drinking Water, RO System, Pool

The pH meter and TDS meter kit is a cost-effective product that offers practical testing data. This combined unit would be more economical and convenient than purchasing the components separately, while still allowing the pH meter and TDS meter to be used independently as needed.

Specifications for the pH meter include a measurement range of 0.00-16.00 pH, a resolution of 0.01 pH, and an accuracy of ±0.01 pH. It is powered by 2 x 1.5V (LR44 button cell) batteries, which are included, and can operate in temperatures from 0°F to 140°F.

The TDS meter has a measurement range of 0-9999 ppm (with readings over 999 ppm displayed x10) and an accuracy of ±2%. It also operates on 2 x 1.5V (LR44 button cell) batteries, which are included, and can function in temperatures from 32°F to 122°F.

Both the pH meter and TDS meter feature Automatic Temperature Compensation (ATC), ensuring the measured data is not influenced by water temperature when testing pH or TDS. This makes the readings accurate regardless of the ambient conditions.

For user convenience, the pH meter has a single "CAL" button to calibrate the device to pH 4.01, 6.86, or 9.18 buffer solutions. The TDS meter requires no calibration, as it was pre-calibrated during production. Both meters have automatic shut-off functions, turning off after 5 minutes (pH meter) or 10 minutes (TDS meter) of inactivity to conserve battery life.

In terms of physical design, the pH and TDS meter kit is compact and portable, with a pen-like size and low weight that makes it easy to carry in a pocket or bag. This makes it convenient to take the testing equipment with you when needed, whether in the field, lab, or at home.

Overall, this combination pH and TDS meter provides accurate, temperature-compensated measurements in a user-friendly and portable package. The ability to test both pH and TDS with a single kit is a cost-effective solution compared to purchasing the components separately. The straightforward calibration and operation of the meters further enhance their practical utility.
