5 in 1 Multi-function - This digital pH value is designed with 5 groups of functions, which can be used to test pH/tds/ec/ec/salinity/dirty/salition/salition/sater temperature. The measurement range is pH 0.00-14.00 (accuracy 0.01PH) Level: IP67 Green Backlit LCD Display Design- This pH meter design features a bright green backlit LCD display to display information in an intuitive layout. Even with low visibility, you can still read the numbers. It is also convenient to carry with the portable pocket design. 5-minute auto shut-off design saves power and ensures battery life. High Accuracy pH Tester]- The glass probe of this pH tester is made of of a low-resistance glass-sensitive film (25 m) and the response speed is 0.1 seconds. TDS electrodes are made of agile and high quality titanium alloy with perfect corrosion resistance. pH uses a three-point calibration method to calibrate pH 4.01/6.86/9.18 solutions to ensure measurement accuracy. Automatic compensation and calibration Temperature Liquid temperature can affect reading levels, but our digital pH water tester can accurately measure sample pH over a temperature range of 0C to 60C / 32 to 140 F, and pH Value tester can automatically identify the calibration solution to read the numbers at a glance. WIDE APPLICATIONS- This 5-in-1 multifunctional pH tester is ideal for home and laboratory pH testing applications, it can be used for testing drinking water, swimming pools, aquariums, spas, aquaculture, indoor ponds and wells or while on vacation. /p>
