5 in 1 pH Meter with Salinity Temperature TDS EC High Accuracy Multifunctional Waterproof Tester Automatic Temperature Compensation Self-Calibration Digital Ph Tester

5-in-1 pH Meter: This pH meter simultaneously measures pH, TDS (ppm), conductivity (EC), salinity (ppt) and temperature with high accuracy. High Accuracy: The high-precision algorithm chip and high-sensitivity probe allow you to quickly obtain accurate results. The green backlit LCD display allows you to easily read the measurement results under any circumstances. Simply press the HOLD/TEMP button to lock the measured value and remove it for easy viewing Automatic Calibration: You no longer need to worry about calibration, because the pH meter has an automatic calibration function, also known as the 3-point calibration method, and comes with a calibration powder (standards: pH 4.00, pH 6.86, pH 9.18) Automatic Temperature Compensation: The pH meter no longer needs to pay attention to the temperature of the test liquid, the pH meter can accurately determine the pH value of the sample within the temperature range of 0°C-60°C (32°F-140°F), to solve the inaccurate problem caused by the change of liquid temperature Wide Application: The pH meter can be carried anywhere to measure your aquarium, swimming pool, garden pond, bathtub to test pH value levels, can also be used to measure drinking water, system reverse osmosis system, spa, soap mixture, food, wine, beer, or any other liquid Backlight design LCD Large backlit LCD display for easy reading of results in all conditions. The soft green backlight protects your eyes from glare. Reliable ATC Function By long pressing the "HOLD/TEMP" button, the temperature unit C/°F can be converted from 0 to 60°C/32 to 140°F. All measurements are automatically temperature compensated. Temperature sensors are faster and more accurate than direct contact with the measured solution. High-quality pH sensor The pH meter's high-sensitivity water glass probe is made of a low-resistance (25 MΩ) glass sensitive film, which greatly improves its sensitivity and accuracy to 0.01.
