The pH and TDS Meter Combo is a water testing kit that combines a high-accuracy pH tester with a 3-in-1 tester for TDS, EC, and temperature measurements. Both testers feature ultra-sensitive electrodes and Automatic Temperature Compensation for water-quality monitoring across a range of applications.
Designed for straightforward testing and reading, the meters feature backlit LCD screens, a hold function for locking readings, and a memory function that preserves settings after power interruptions. The kit is suitable for drinking water, swimming pools, spas, RO systems, hydroponic systems, aquariums, and other water-quality applications.
Key Features
-
Combined Water Testing: Includes a high-accuracy pH tester and a 3-in-1 tester for TDS, EC, and temperature measurements.
-
pH Measurement: Measures pH from 0.00 to 14.00 with ±0.1 pH accuracy.
-
Automatic pH Calibration: Features one-touch automatic calibration and includes buffer powder packs for setup.
-
3-in-1 TDS Testing: Measures total dissolved solids, electrical conductivity, and temperature.
-
Automatic Temperature Compensation: Both testers feature ATC to compensate for changes in water temperature during measurements.
-
Backlit LCD Screens: Large backlit displays provide clear readability in different lighting conditions.
-
Hold Function: Locks the displayed reading for easier viewing and recording.
-
Memory Function: Preserves settings after power interruptions so settings do not need to be reset after an unexpected shutdown.
-
Multiple Water-Testing Applications: Suitable for drinking water, swimming pools, spas, RO systems, hydroponic systems, aquariums, and other water-quality monitoring applications.
