Title: Waste of $$$
Review: I had the idea that this could be hooked up into my solenoid to deactivate the solenoid when the ph gets below a range I have set. Nope! The damn thing just sits in the water and reads your ph. It is a waste. You're better off getting a drop checker. Not to mention the yellow ph probe is an eyesore.Also, you are given step by step calibration directions to ensure that the readings are correct. They have you calibrate it at a ph of 7 and a ph of 4. They give you a ph of 7 solution to calibrate with...but they don't give you a ph solution of 4 to calibrate with. What garbage!!!I have purchased other products from Milwaukee before...but this was horrible.
