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. The replaceable probe design with an insert-type mechanism makes replacement quick and easy.10. Ergonomically designed with anti-slip features on both sides for ease of use.11.
