- Reviewed in Canada on July 14, 2020This is not accurate at all. I used one tds meter it said approx 200 tds of the item which was to be 342ppm. I tried to recalibrate the pen and broke it. I ordered another tds pen which cost $40 and surprise it reads at 200 not 343ppm. I am not going to adjust the pen up 142ppm as then it will tell me my ro unit water is 142ppm which it is not. I cannot blame 2 different TDS pens with exact same measurement of 200ppm as being wrong. This product is faulty.
