DA Meter - Portable Instrument for the Measurement
The ΔA Meter is a portable instrument for the measurement of the ΔA Index® in laboratory and on the field. This equipment combines simplicity of utilization to good quality of taken measures, and enables either to make immediately use of the obtained data or to store them for a future employment. To that extent, it is provided with a SD Card (having a maximum capacity of 2 Gbyte, which is enough to store a quantity of measures absolutely bigger than the real necessities), and with a USB interface which enables linking to a computer immediately
The instrument exists in different versions that differ from each other for the size of the sensor, which may be more suitable for small fruits (such as cherries) or larger fruits (such as apples) and for the number of wavelengths used for measurement. There are some types of fruit for which it is necessary to use different wavelengths than those normally used on standard fruit and some (such as actinidia) for which different wavelengths are required depending on whether it is the yellow or green variety.
The standard instrument, characterized by the yellow protective shell, uses only one wavelength and is equipped with a head suitable for fruits of normal size.
The front side of the three versions of the instrument, equipped with different sensor tipologies: standard 13mm sensor for standard climateric Fruits (yellow/orange livery), small size 9mm sensor for Actinidia -Kiwifruits (green livery) and for Cherry (red livery)
