It seems that the calibration solutions I have purchased for my Hanna meter are not doing the trick. Someone wrong with what I am doing perhaps?
I rinse the probes off in tap water (I have a grounding, pH and ppm probe) and then proceed to the 1382 ppm test solution. Calibrates fine, a quick rinse and into the 1500 I go. The meter will now read 1900, off the scale, so I adjust the screw on the front of my meter to get the read proper. Then, back to the tap water and into the 1382 again, which now reads 900.
the pH will calibrate fine, I just can't seem to get the ppm correct. Any thoughts?
