No guarantees...
Product worked on clear tap water, fresh snow and mountain river water for ~ 20 samples with no issues and I was quite pleased to start. However, after the second or third calibration with standards, an error 4 came up and the standards did not match the expected calibration (75ppm for 150ppm STD: 1100 for 2000ppm STD), nor did re-calibration work. I need to replace the sensor according to the instructions.
