Verification vs.

Calibration

Verification

Your instrument needs to be verified with a primary

and a secondary verification standard every day.

Standards are salt solutions with known water

activities. Measuring one standard at the bottom

of a water activity range and one towards the top

of the range will alert the operator to shifts in the

calibration.

Calibration

If a shift occurs and you notice that the standard

isn't measuring in spec, the first thing you need

to do is clean the instrument. If the standard is

still not measuring in spec after cleaning you can

adjust the calibration up or down using the .920,

.760, or the .250 standard.

*Standards come in boxes of 50 plastic disposable vials and the

four types you can use with the Pawkit for verification include the

.920,.760, and the .250.

*Note: Adjusting the calibration of the instrument should only be

done when the verification standards are reading out of spec.

If you need help determining which standards

to use to verify your instrument or you can't

get you instrument to measure within spec

of the standards, please contact AquaLab
