7 in 1 PH/TDS/EC/ORP/SG/Salinity/Temperature Pocket Water Quality Tester Multi-Parameter with Electrode pH Meter C-600 Replaceable for Pools Drinking Water Aquariums

• Can measure PH / TDS / EC / ORP / SG / Gravity / Temperature specific to sea water. The measuring range is wide and wide and can measure freshwater salinity and sea salt.
• IP67 is an international water and dust proof certification. Protection against dust intrusion, short duration immersion.
• This product can detect the salinity of edible salt. At the same time, it can detect seawater salinity. Food salinity measurement range: 0.00-25.00%, seawater salinity measurement range: 10.1-200.0ppt.
• Auto shut-off function turns off power after 5 minutes without any operation to save energy. Use a fully transparent liquid crystal (LCD) to display 4 digit values and corresponding physical quantity units.
• Portable TDS meters can be transported anywhere to measure water quality, such as tap water, RO system water, aquarium, sea water and pool water.
