3 in 1 TDS, EC and Temperature Meter with Digital LCD and 4 Different Modes of Water Level Testing.
The LCD screen is convenient for reading and recording data and stores readings for easy reading and recording, and the digital LCD TDS meter is used to test the purity of the filter water quality, to check the performance of your water filter and to check the hardness (1 grain = 17 ppm) .To ensure that you always drink clean and safe water.
Auto-off function: Switch off the meter after 5 minutes of non-use to save the battery
Automatic temperature compensation function when the meter is in measurement mode.
You can switch between TDS and conductivity by clicking the SHIFT key, double-clicking the SHIFT key, and switching between Celsius temperature and Fahrenheit.
