I have the same experience as the previous 1 star reviewer. The product is absolutely not working properly. Readings far, far away. The meter was taken right out of the box and freshly calibrated (and yes, I'm experienced enough to read the instructions and calibrate properly, [to the smug replyer of another 1-star review] and by the way, I don't have it understood probe cleaning cloth as indicated in the product description). The numbers were so low that I sent my water electrolysis machine back to the manufacturer for service, thinking something might be wrong even though it had been thoroughly cleaned. They went all the way through the machine and again cleaned it thoroughly and said the calcium build up was very low (only level 1 of 5) and checked the ORP. These numbers turned out to be similar to the numbers I got when the car was new and with a different ORP meter in my own water source. Got my car back and tested again after another gauge recalibration. Same thing happened and obviously the reader or sensor broke right away and now I have to buy another one from someone else and my $150 was a waste of money.
