Neptune Systems Conductivity Calibration Solution - 53.0 mS

This is the perfect way to package calibration solution as far as I'm concerned. Don't forget to get the solution to temperature before using it to calibrate your probe. Good product, the probe however... not so much.

not much to say about a calibration solution. its easy to use and seems accurate

Just insert your probe and wait 10 minutes for accurate calibrating

tried another product to calibrate originally and was off on the salinity, but when I used this product it matched my refractometer perfectly!!

Everything always just works with Neptune Systems. I decided to get backup solution.
