1. pH Measurement Range: 0.0~14.0pH2. Portable pH meter, high accuracy, stable operation. It measures the pH value of a solution and displays the temperature of the liquid being measured. Widely used in: industry, power, agriculture, medicine, food, scientific research, and environmental protection.3. When the pH value is below 3.5, the red backlight illuminates as an alarm, indicating that the liquid is approaching strong acidity; when the pH value is above 12.5, the red backlight illuminates as the liquid is approaching strong alkalinity.4. Automatic temperature compensation from 0 to 70 degrees Celsius; temperature has a certain impact on pH measurement, and the impact is even greater if high accuracy is required. Therefore, a high-precision pH meter with intelligent temperature compensation is essential.5. The instrument features a dual-color alarm and a night backlight, which can intuitively display the measured value. In measurement mode, if the measured value exceeds the range, the white light changes to a red over-value warning light, easily handling dark environments.6. This instrument features a three-point pH calibration function with automatic recognition and a simple, quick calibration process.7. A high-precision pH probe ensures faster and more accurate measurements, safeguarding precise water quality testing.8. Powered by two 1.5V AAA batteries, it is durable and easy to replace.9.
