This video reviews 3 Yieryi water quality meters used for Hydroponics, fish tanks, and fish ponds.
One is a handheld TDS and PH meter that is semi waterproof.
The other two are 6 in 1 meters that between them measure salinity, TDS, PH, EC, CF, humidity, and temperature.
The last one I review has WiFi connectivity with remote monitoring and alarm messaging. Included is step by step programing instructions.
