I totally understand! Although, I have found that the best way to calibrate the unit is to test your water by hand with whatever test kit you trust most, and input those values into the trident for a calibration. It’s an extra step, but I find that the trident reads a little more accurately when doing it this way as well
The deal breaker for me is they don't sell Calibration fluid.
