I calibrated my trident and used the water sample to test the accuracy of the Hanna (assuming the calibration fluid is 100% accurate). I was surprised at the results of the alk.
Hanna alk read 9.1 on 8.42 calibration fluid. Difference of .68
Hanna cal read 424 on 445 calibration fluid. Difference of 21
salifert mag was probably within 10 of calibration fluid.
