The tester stop working after one month of use
I bought the tester a month ago. I would use it maybe twice a week., but today the battery low display came on and I replaced the batteries with new batteries. I made sure that no water went into the battery compartment and while using it made sure not to submerge the tester pass the test line. Now after replacing the batteries all I get on the display reading is 0PPM. I tried swapping them out with other batteries and same thing displayed. I'm really not happy with the out come after purchasing the tester a month ago.
