7-in-1 Multifunctional pH Meter, Professional Grade High Accuracy Measurement of TDS, pH, EC, Salt, ORP, SG and Temperature Water Testing Kit

Multifunctional high accuracy measurement of TDS, pH, EC, SALT, ORP, S.G., TEMP (℃/℉) water testing kit for seawater or freshwater quality testing, hydroponics, water purification applications, wastewater regulation, farming, aquaculture and more.

High-precision algorithm chip and high-sensitivity probe ensures you can quickly get accurate results in the temperature range 0°C-60°C (32°F-140°F).

The Ph meter with an auto calibration feature, also known as the 3-point calibration method, comes with calibration powder (standards: pH 4.00, pH 6.86, pH 9.18).

Unlike many other similar devices, our 7-in-1 pH meter is ideal for testing pool water/hot tub for salinity/pH, SALT: 0-25%; 1-10000 ppm; 10.1-200.0ppt; closely monitor pH and ppm values while growing your plants, TDS:1-9999ppm, 1ppm; check and adjust pH and EC values in hydroponic nutrient solution, EC:1-19999μs/cm, 1μs/cm; ORP (oxidation reduction potential): -999mV~+999mV measures water molecule’s ability to oxidize.

When attempting to disinfect and sanitize the water with ozone, bromine, or chlorine, ORP can be used to identify how effective disinfection is; S.G.

(specific gravity or density): 1.000-1.222, is a ratio of the weight of the water to the specific volume.
