2020 new design water quality test pH test analyzer with pH test sensor by Hangzhou Lohand Biological Technology Co.,Ltd..Including the pH test meter and pH sensor . Features 1.Wide screen LCD display, with operation prompt function, easy to use. 2.Using 32-bit microprocessor technology, with automatic temperature compensation. 3.It adopts lithium battery power supply and has the power management function of charging and power failure protection. 4.Low power consumption design, the backlight is turned on and off automatically by external light. 5.The protection grade is IP65, waterproof and dustproof. 6.Three kinds of pH buffer reagents can be selected for one-point or two-point calibration of the instrument. Note: 1. During the intermittent period of electrode use, please clean the electrode test end with pure water. 2. If the electrode is not to be used for a period of time, it should be rinsed clean, dried up the remaining pure water, and stored in the soaking solution. 3. After long-term use of the electrode, the slope and response speed of the electrode may decrease. The measuring end of the electrode can be immersed in 4% HF solution for 3-5 seconds or in dilute HCl solution for 1-2 minutes. After washing with pure water, soak in potassium chloride (3mol/L) solution for more than 24 hours to renew. 4. The electrode bulb should not be in contact with grease, especially organic silicon substances. 5. Before and after the measurement, the electrode should be cleaned with pure water to ensure the accuracy of the measurement.
