Parameters: Product Style: Built-in Electrode Resolution: 0.01PH Detection Range: 0.00~14.00PH< /p> Calibration method: Automatic 2-point calibration Temperature compensation: Automatic ATC compensation Battery type: 21.5V button battery Product size: about 15531*18mm Product net weight: about 50g Wide measuring range: This pH meter can be used to measure the pH in a range of 0.00 to 14.00 which is ideal for household and laboratory applications such as beverages, drinking water, swimming pools, spas, aquarium, hydroponics, etc. Automatic temperature compensation: No more need to pay attention to the temperature of the test liquid, because the ph meter has built-in automatic temperature compensation (ATC), so that it can accurately determine the pH value of the sample at any temperature within a range of 0°C to 80°C (32°F - 176°F). High sensitivity bulb and clear display: Glass bulb electrode precision temperature sensor is for improving the reaction speed. Read clear data. Suitable
