Resolution Measurement Two Color Temperature Compensation Review

【HIGH SENSITIVITY AND ACCURACY】 The PH tester designed and made with precise components ANS sensor, it have high sensitive and accuracy, stable to work with different temperature. The probe has high sensitivity and can quickly respond to H+ in the solution. It is made at 1000°C with low-impedance glass sensing film. 【EASY TO USE AND CALIBRATE】Calibrate once per week if you often test solution of PH 10, or once per half month for neutral solutions. The 250ml calibration solution for multiple uses (10ml or so each time). Then rinse the electrode with pure water before next test. Rinse and rest 3-5 min before conversing from strong acid to strong alkaline and vice versa. You can get the PH testing result of the water that just need to press the button of "ON", and need to press the button "OFF" to close it. 【ALARM PROMPT】The PH meter has a dual-color alarm and night background light to directly displays the measured value. If the measured value exceeds the range, it will change from white light to red warning light. When the pH is lower than 3.5PH, the red backlight lights up, indicating that the liquid is close to strong acid; when the PH value is higher than 12.5PH, the red backlight lights up, indicating that the liquid is close to strong alkali. 【AUTOMATIC TEMPERATURE COMPENSATION】The PH meter has a range of 0-70 degree and ensure that you're getting the best possible reading. Digital ppm tester and PH tester both have the function of ATC, the measuring data won't be influenced by the water temperature, no matter testing the ppm or PH of the water. 【WIDE APPLICATION】This PH meter is an intellectual precise measurement apparatus, with small size for easy storage and hand carry, very practical in life. This pocket size PH Meter is the ideal test kit for home, laboratory, pools, aquariums, spas, hydroponics, food, wine and beer making and more.
