Product Feature
💧 High precision: The high-sensitivity probe provides you with a complete measurement range, multi-function switching at will, with data retention function and low-battery indication function.
💧 Automatic Shutdown Function and Large Screen Display: The automatic shutdown function automatically turns off the power after 5 minutes without any operation to save power. It adopts a backlit high-definition display screen to display 4-digit values ​​and the corresponding physical quantity units.
💧 PH Tester Wide Range of Applications: Versatile, ideal for home and laboratory pH testing applications including drinking water, swimming pools, ponds, beer brewing, kombucha, aquariums, hydroponics, laboratories, food processing, and more.
💧 7 in 1: The water quality test pen is a 7 in 1 style. PH, TDS, EC, salinity, ORP, temperature, SG can be measured simultaneously with high precision. The measurement range is large and wide, which can measure freshwater salinity and sea salt, and measure water quality in all directions to ensure healthy water quality.
