HAND-HELD DEVICE FOR ANALYZING QUALITY OF FOOD PRODUCT AT EARLY STAGE

ABSTRACT 'Hand-held device for analyzing quality of food product at early stage' The present invention relates to a hand-held device for analyzing quality of food product, comprising: a sensing probe has inner lines spaced apart and surrounded by outer lines, where the outer lines are dissimilar conductive elements. A controller is coupled to the inner and outer lines of the probe through respective first and second resistive elements. A relay is coupled to the outer lines of the sensing probe and operated by the controller. An indicator is operatively connected to the controller. Once the sensing probe is inserted into the food product, the controller transmits a power signal and at least one frequency signal to the probe, so that the controller determines multiple parameters of the food product by switching on the relay to measure conductivity across the second resistive element at different frequency signals and by switching off the relay to measure potential difference across the outer lines of the probe. The indicator is operated by the controller based on the determined parameters of the food product. Thus, the hand-held device achieves rapid, instant and easy analysis of quality components of food product in the field itself. FIG. 1
