HD-3A type water activity meterusage method:

1. Installation



Install the instrument according to the diagram (the plugs correspond one-to-one and cannot be connected incorrectly)


Crush the object to be tested and place it in a plastic container, then insert it into the sensor and cover the sensor.


Due to the intelligent processing of data, onlyPress the confirm button, and the instrument will automatically perform the measurement. After completion, the measurement results will be displayed and printed (due to the use of a waterproof keyboard, the instrument can work stably and reliably even in the presence of water or oil stains)
Due to the use of a new type of highly stable sensor and the calibration equipment used before leaving the factory, the new instrument can be used directly without calibration.
