Reliable and portable pH meter designed for stable and easy on-site measurements. All pH readings feature automatic temperature compensation (ATC) for enhanced accuracy. Automatic calibration feature allows for precise measurement. Calibration and measurement processes are quick and reliable due to an intuitive interface that corrects temperature-related errors. Measurement parameters include a range of 0-14 pH and temperature from 0-100°C, with a resolution of 0.01 pH and 0.1°C. Accuracy is ±0.01 pH and ±0.5°C, ensuring reliable results. User-friendly operation with a dual LED display showing both pH value and temperature simultaneously. The four-digit display shows pH, while the three-digit display shows temperature. Versatile application across various fields including agriculture, aquaculture, food production, water purification, and more, making it ideal for both professional and home use.
