Product Questions

I just received my Milwaukee pH meter and the directions indicate it needs calibration with pH 7.0 solution. My question is how often does this unit need calibration? My comment is since the package does not come with the calibration solution it would be nice if you indicated this solution needs to be purchased. Thank you

Great question! We typically calibrate our pH probes at least quarterly. This is to ensure consistent and accurate readings. Here is our favorite calibration solution in the link below. :-)
