7 in 1 Salinity Meter PH TDS EC ORP S.G TEMP Water Quality Tester Swimming Pool Monitor Aquarium.

7 in 1 Salinity Meter PH TDS EC ORP S.G TEMP Water Quality Tester IP67 Swimming Pool Monitor Aquarium Analysis Instrument Features: It can measure PH / TDS / EC / ORP / S.G/seawater specific gravity / temperature. The measurement range is large and wide and can measure freshwater salinity and sea salt. This product can detect the salinity of edible salt. At the same time, it can detect the salinity of seawater. Food salinity measuring range: 0.00-25.00%, seawater salinity measuring range: 10.1-200.0ppt. IP67 is an international waterproof and dustproof certification. Protection against dust intrusion, short-time immersion. Portable TDS meters can be carried anywhere to measure water quality such as tap water, RO system water, aquarium, seawater, pool water. The automatic power-off function turns off the power after 5 minutes without any operation to save power. Employs a fully transparent liquid crystal (LCD) to display 4-digit values and the corresponding physical quantity units.
