TOPWAY 4 in 1 Digital Water Quality Tester PH TDS EC Temperature Meter Pen Hydroponics Aquarium Pool Spa 150134
Product Overview
The TOPWAY 4-in-1 Digital Water Quality Tester (150134) is a compact, high-precision electronic testing pen designed to quickly analyze four critical water parameters: pH level, Total Dissolved Solids (TDS), Electrical Conductivity (EC), and Temperature (°C/°F). Engineered for both home and professional use, this versatile meter eliminates the need for multiple liquid chemical reagents and test strips.
Manufactured from durable ABS material, the tester features a clear digital display, automatic temperature compensation (0–60°C), factory-calibrated EC/TDS sensors, and 3-point pH calibration options. Supplied complete with 3 × 1.5V button cell batteries included, a 5-minute auto-power-off function, and low-power protection, it is an ideal tool for monitoring drinking water sources, hydroponics systems, aquariums, swimming pools, RO water systems, and spas.

Operating & Care Guidelines
-
Measurement Procedure: Turn on the tester, dip the electrode into the liquid sample, stir gently, and wait for the digital reading to stabilize.
-
Maintenance & Storage: Clean the electrode tip with distilled water after every test and replace the protective cap to prevent sensor drying.
-
Calibration Check: Re-calibrate the pH sensor periodically using standard buffer solutions if measuring extreme pH fluids or after extended storage.
