Review on ๐ HM Digital COM 80 Electrical Conductivity: Boost Water Safety with Advanced Monitoring Technology by Scott Channell
Hazardous waste
Terrible. I bought some calibration fluid with this pen to make sure it's accurate. Although it was "factory calibrated for immediate use," it differed by 200 ppm from the calibration fluid. Whenever I tried to calibrate it, it always gave me an error message. According to the instructions, "Err" messages indicate internal damage or "the meter cannot calibrate" but do not provide advice on how to fix it. The $12 ppm tester I've used for years is more accurate than this $30 bunch of hot junk. Don't believe this bizarre disappointment.
