Electronic pH Meter, 5-in-1 Pool Water Tester with Backlight, pH/TDS/EC/Salinity/Temperature with ATC, High Precision pH Meter

General Description: This 5-in-1 electronic tester is a high-precision and versatile measuring instrument for water quality analysis. It combines the functions of measuring pH, TDS (total dissolved solids), electrical conductivity (EC), salinity, and temperature, all with automatic temperature compensation (ATC). Its backlit LCD screen and waterproof design make it a reliable and easy-to-use tool for swimming pools, aquariums, spas, drinking water, and many other applications. Technical Specifications Measured Parameters: pH, TDS, Electrical Conductivity (EC), Salinity, Temperature Measurement Range and Resolution: pH: 0.00 - 14.00 pH (Resolution: 0.01 pH) TDS: 0 - 9999 ppm (Resolution: 1 ppm) EC: 0 - 9999 µS/cm (Resolution: 1 µS/cm) Salinity: 0 - 99 ppt (Resolution: 0.1 ppt) Temperature: 0 - 99 °C (Resolution: 0.1 °C) Automatic Temperature Compensation (ATC): Yes (built-in) Display: Digital LCD with backlight Power Supply: 2 x button cell batteries Waterproofing: Waterproof casing Battery Life: Automatic shut-off to save battery power. Features and Benefits: 5-in-1 Multifunction: A single compact device replaces multiple instruments, enabling comprehensive water analysis. High Accuracy and Resolution: 0.01 resolution for pH, ensuring precise and reliable readings for rigorous monitoring. Automatic Temperature Compensation (ATC): Automatically corrects measurements based on water temperature, guaranteeing consistently accurate results. Backlit LCD Screen: Allows for easy reading of results, even in low-light conditions (covered pool, under an aquarium cabinet). Simple and Intuitive Operation: Easily switch between different measurement modes. Ideal for both home and professional use. Practical Design: Waterproof and durable housing. Automatic shut-off to extend battery life. Operating Instructions (General Procedure) Calibration (Recommended): For optimal results, first calibrate the pH meter using the calibration buffer solutions (pH 4.01, 6.86, 9.18). The solutions are not usually included. Preparation: Rinse the electrode with distilled water. Measurement: Turn on the device, select the desired mode (pH, TDS, etc.). Immerse the electrode in the water sample to be tested, without touching the sides. Gently agitate. Reading: Wait for the value to stabilize on the screen (a few seconds). Note the result. Recommended Applications: Control and maintenance of swimming pool and spa water (pH, TDS). Monitoring water quality in aquariums (freshwater and marine). Testing the purity of drinking water or tap water. Use in hydroponics and agriculture to monitor nutrient solutions. General water analysis in educational laboratories, kitchens, or for scientific projects.
