Features 【MULTIFUNCTION】 - This digital PH meter is equipped with a 5-in-1 function that can test PH/TDS/EC/Salinity/Temperature of water. PH meter the measuring range is pH 0.00-14.00, TDS 0-10000ppm, 10.1-200.00 ppt, EC 0-10000uS/cm, 10.1-19.99mS.20.1-400.0mS/cm, salinity 0.01%-25.00% and PH value measuring instrument pool temperature 0-60℃. 【LCD DESIGN】 - This PH meter is equipped with a clear green backlit LCD screen that displays the information in an intuitive layout. You can read the digital image even in poor visibility conditions. PH meter and 5-minute auto-off design saves power and ensures battery life. 【HIGH ACCURACY PH TESTER】 - The glass probe of this PH meter is made of a glass-sensitive film with low resistance and the response speed is within 0.1 seconds. made of a maneuverable, high-quality titaniu alloy with perfect corrosion resistance. 【AUTOMATIC TEMPERATURE COMPENSATION】PH meter liquid temperature may affect the reading, but our digital pH water quality tester can accurately measure the pH of the sample and pH meter pool in the temperature range of 0℃-60℃/32-140℉ The calibration solution can be automatically detected for quick reading of the digital display, and the waterproof function of the water quality pen is improved. 【WIDE APPLICATION】 - This multifunctional 5-in-1 PH meter is ideal for home and laboratory pH testing applications that measure the quality of drinking water, swimming pools, aquariums, hot springs, aquaculture, ponds, and indoor well water on vacation to ensure water safety in daily life. If you have any problem with the product, please do not hesitate to contact us! Function: 1. Applicable to garden, home, laboratory, farm, aquarium, etc. 2.
