Digital pH meter in pocket size, perfect for testing the pH value in pools, aquariums, spas or water for food and drink. pH meter makes it easy to always maintain the ideal pH balance and measures with great accuracy. This pH meter has built-in automatic temperature compensation (ATC) so that it can determine The pH value of a sample with precision at any temperature in the range 0 C - 60 C. It instantly adapts to the current water temperature without you having to take this into account. The pH tester has an extremely sensitive electrode sensor for accurate pH readings. A detailed manual is included to show you how to get accurate measurements. Has an automatic calibration function - easy to calibrate with the push of a button and using the supplied buffer powder. Contains 3 bags of buffer powder (pH 4.01, pH 6.86 and pH 9.18). Specifications: Colour: Yellow p> Measuring range: 0.00 - 14.00 pH. Accuracy: 0.01 pH Power supply: 2*1.5V Ag13 LR44 batteries included.< /p> Operating temperature: 0-45 C Digital pH meter in pocket size, perfect for testing the pH value in pools, aquariums, spas or food and drinking water. pH meter makes it easy to always have the perfect pH balance, and it measures with great accuracy.
