Does anyone have any experience with this meter? I have full time access to one. The readings that I get from the probe are all a bit lower than I get from hobby grade equipment. The YSI unit is maintained and calibrated by a USGS Hydrologist/Geologist(my wife)
Should I be chasing any of these numbers? I am going to adjust my temperature accordingly.
TEMP
lab immersion thermometer (alcohol) - 78
556 mps - 74.75
PH
50$ Milwaukee probe - 8.1 (calibrated 7 &10 before each use)
556 mps - 7.6
SG
Amazon refractometer (calibrated w/ ocean water) 1.026
556 MPS 50.0822 = 1.025
Other parms I don't check with hobby equipment:
DO 6.3mg/l 90.6%
ORP 80.9
