Water activity analyzer
ملحوظة: Because the data has been intelligently processed, so just press the confirm key, the instrument automatically measures, after the end of the display and print the measurement results (because of the use of waterproof keyboard even if there is water, oil stains the instrument can also be stable and reliable work) due to the use of a new high stability sensor, And the calibration equipment has been used before the factory (the accuracy of the calibration equipment can be traced to the National Bureau of Metrology) for calibration, so the new instrument can be used directly without calibration.
Water activity analyzer
