5-in-1 Electronic pH Meter Tester, pH Meter with Backlit LCD Screen, Water Quality Tester for Testing pH/TDS/EC/Temperature/Salinity, for Drinking Water/Aquariums/Swimming Pools

【5-in-1 Multifunction】 - This digital pH meter is designed with a 5-in-1 function, which can be used to test the pH/TDS/EC/salinity/temperature of water. The measurement range is pH 0.00-14.00 (accuracy 0.01 pH), TDS 0-10000 ppm, 10.1-200.00 ppt, EC 0-10000 µS/cm, 10.1-19.99 mS, 20.1-400.0 mS/cm, salinity 0.01%-25.00%, and temperature 0-60°C. Waterproof rating: IP67. 【Green LCD Backlit Display Design】 - This pH meter is designed with a bright green backlit LCD screen that displays information in an intuitive layout. You can always read the digital display even in low-visibility conditions. Its portable, pocket-sized design makes it convenient to carry. The 5-minute auto-off feature saves power and extends battery life. 【HIGH-PRECISION pH TESTER】 - The glass probe of this pH tester is made of a low-resistance glass-sensitive film (25MQ) with a response time of 0.1 seconds. The TDS electrodes are made of high-quality, agile titanium alloy with excellent corrosion resistance. The pH meter uses a three-point calibration method to calibrate the electrode to a pH solution of 4.01/6.86/9.18 to ensure measurement accuracy. [AUTOMATIC TEMPERATURE COMPENSATION AND CALIBRATION] - Liquid temperature can affect readings, but our digital pH water quality tester can accurately measure the pH value of the sample within a temperature range of 0°C to 60°C / 32°F to 140°F. The pH tester can automatically identify calibration solutions for a quick digital reading. [WIDE APPLICATION] - This 5-in-1 multifunctional pH tester is ideal for home and laboratory pH testing applications. It can be used to test the quality of drinking water, swimming pools, aquariums, hot springs, aquaculture, ponds, and well water indoors or during outdoor use.
