4-in-1 pH Meter Water Tester TDS EC Temp High Accuracy Backlit

1. [4-in-1 Tester] This pH meter has a 4-in-1 design with numbers displayed on the LCD screen, which allows you to know the pH value, TDS value, EC valueand water temperature in seconds.

2.[Accurate and reliable] The pH range is 0-14, resolution ±0.01 pH, accuracy ±0.01 pH. TDS range is 1-9999 ppm, resolution 1 ppm. EC range is1-1999s/cm, resolution: 1us/cm, accuracy: ±2%FS. Temperature measuring range is 0-60℃, resolution: 0.1, accuracy: ±0.5℃.0.5℃.

3. [Automatic shutdown] In order to extend the life of the tester, we have designed an automatic shutdown function.If it remains inactive for 5 minutes, it will automatically turn off.It also features automatic temperature compensation and automatic calibration for more accurate measurements.

4. [Portable] pH meter is portable and lightweight, not only compact but also easy to use.It is suitable for testing the pH balance of drinking water, swimming pools, aquariums, reverse osmosis systems, hydroponics and spas.

5. [Calibration method] pH value: place the device in a standard solution, press the CAL key to automatically calibrate (place the device in a standard solution of 6.86, press the CAL keyfor 5 seconds, the calibration of 6.86 will indicate that it is completed);TDS value: Place the device in 1413 standard solution, press CAL key for 5 seconds, it means 1413 calibration is completed.Translated with www.DeepL.com/Translator (free version)
