This lot consists of 2 water testers - pH and TDS meters.

The pH meter features in-built calibration with 2 buffer powders, so you can just press a button to finish the calibration. No more fiddling around with annoying charts and test strips. It's pocket-sized and lightweight, so you can take it with you wherever you go. It has a resolution of 0.01 pH and an accuracy of ±0.01 pH, making it extremely precise. The large LCD screen makes it easy to read your results. Whether you're monitoring water quality in an aquarium, swimming pool, or other setting, this meter is up to the task. pH measuring range is from 0.0 to 14.0.

The TDS meter has a titanium probe. Total Dissolved Solids (TDS) are the total weight of all solids (minerals, salts or metals) that are dissolved in a given volume of water, expressed in milligrams per litre (mg/L) or in parts per million (PPM).  Advanced CPU: automatically calibrated per temperature, 0 - 9990 ppm TDS measurement range with 1 ppm resolution, +/- 2% readout accuracy. Data Hold Function: holds measurement value when moving out of water for convenient reading and recording. Auto-off Function: shuts off automatically after 10 minutes of non-use to conserve batteries. ATC and Temperature Function: ATC function promises high accuracy and the Temperature Function allows users to get to know the water temperature. Measurement accuracy is +/-2%. Item's size is 154 mm x 29 mm x 19 mm. Weight: 72g.

Both testers need 2 x 1.5V LR44 batteries. The batteries are not included in this lot.
