Review on KINCREA Accurate Reliable 0 9990Ppm Temperature by Dan Barrett

Well it definitely works. I measured the water in my house last night to see if the filtration systems are working: 1. Kitchen sink measured 1532. Reverse osmosis systems under sink 153. Bottled water filter 334. Bathroom sink 665. Shower with new shower filter 66Oooh my assessment - the TDS -Monitor works. Each time he got a different reading, the readings stayed stable. RO sink works PERFECTLY! The water in the house is NOT dangerous but the water in the back of the house is safer to drink than in the kitchen and finally the shower filter I brought here from Revain is a gimmick and a scam.
