Predictive Reading

A predictive reading shows on the screen after about

40 seconds. Reading is complete when your instrument

'beeps' and the LED blinks. Instrument then displays the

sample's final water activity reading and temperature.

Take two readings. The water activity readings should be

within +/- 0.01 water activity of the given value for the

verification standard. If you are using the 0.760 standard

as your primary standard, it should measure between 0.75

and 0.77*. If your primary standard measures in spec,

move on and determine your second verification standard.

If not, clean the instrument and retry the standard. Dispose

of sample cup.

*Accuracy of the AquaLab Pre is ±0.01 water activity.

Note: If you are using an instrument with a volatiles block because of volatiles

in your products, your instrument is in spec if it measures between 0.745 and

0.775. The volatiles sensor for the Pre measures to ±0.015 water activity.
