5-in-1 PH Meter for Water: The pH meter is designed with a 5-in-1 function, which can measure pH (acidity and alkalinity), TDS (total dissolved solids), EC (conductivity), salinity (salt content), and temperature. Seamlessly switch between measurement values with a simple press of the {MODE/CAL} key, ensuring precise control and accurate results for all your testing needs.

3 Salinity Test Modes: GISNPA pH Meter offers three versatile salinity testing modes, covering a range of applications. These modes include general salinity testing (0-9999 ppm), seawater testing (10-200 ppt), and food testing (0.01-25%). It's important to note that TDS and salinity share the same units. Therefore, when measuring salinity, switch the pH meter to the salinity mode to guarantee accurate and reliable results.

High Accuracy pH Meter: Digital pH tester equipped with platinum-plated electrodes and a high-precision algorithm, ensures swift and accurate reactions. Effortlessly stabilize your measured value with a quick press of the {HOLD/TEMP} button, offering convenience at your fingertips. Switch temperature units seamlessly with a simple long press. Uncompromising precision, and simplicity in every step.

LCD Backlit Display & ATC: The PH tester features a large green backlit LCD for easy result viewing in any environment. If there is no operation after 5 minutes, the power will be automatically turned off to save power. The pool tester water thermometer offers an extended range of 0 °C-60 °C (32 °F-140 °F). With automatic temperature compensation, our pH meter for water guarantees optimal readings, resolving inaccuracies arising from varying liquid temperatures.

Wide Applications: The 5-in-1 pH tester is the solution for a variety of applications, including testing household drinking water, hydroponics, swimming pools, aquariums, laboratories, etc. The salinity tester has multiple uses, detecting salt content in edible salt, saltwater ponds, and koi ponds, while also accurately measuring the salinity of seawater, oceans, and saltwater fish ponds.
