I’m thinking about buying the WaterGuru Sense for daily testing and of course continuing with the tfp test kit weekly. Is this device accurate enough for Free Chlorine and PH readings? I’ve found myself using Taylor test strips daily out of laziness and doing full tests 1-2 times a week. I’m curious if this can take the place of test strips. Is the high chlorine level with a salt water pool and the tfp method work with the WaterGuru or is it not able to read numbers that high accurately.
