Portable liquid impedance measurement gauge

Abstract

The invention relates to the technical field of electrochemical methods for detection and provides a portable liquid impedance measurement gauge. The portable liquid impedance measurement gauge includes a shell body, a central control unit is arranged in the shell body, a power source module is electrically connected to an electric power input end of the central control unit, a signal input end ofthe central control unit is electrically connected with an external contact chip fixed to a detection clamp, and an external insertion port is formed in an external connection part, corresponding tothe detection clamp, of the shell body; a man-machine interaction module and an electronic display screen are arranged on the shell body and both electrically connected to the central control unit. The gauge also includes a reaction element, and the reaction element can be electrically connected to the central control unit through the external contact chip. The provided portable liquid impedance measurement gauge is high in integration degree, small in occupied space and light in weight and can not only effectively ensure the precision of liquid impedance detection but also provide conveniencefor carrying, improve the detection efficiency and reduce the usage of stock solutions for detection. The liquid impedance measurement gauge is easy to operate and conducive to application and popularization.

Description

technical field [0001] The invention relates to the field of instruments and meters, electrochemistry, etc., in particular to a portable liquid impedance measuring instrument. Background technique [0002] Impedance measurement has a wide range of applications in the field of medical and health. There are three traditional methods of impedance measurement: automatic balance bridge method, transmission / reflection method, iv (voltage-current) and RF-IV (radio frequency current-voltage) method. The realization of traditional impedance measurement requires multiple small and medium-sized integrated circuits, which have low precision, poor anti-interference ability, complex operation, high power consumption, and it is difficult to realize automatic measurement and use as a portable device; in the process of liquid impedance measurement, traditional The measuring instrument needs a large volume of electrodes, electrode fixtures, measured liquid containers, and test racks to be com...

The realization of traditional impedance measurement requires multiple small and medium-sized integrated circuits, which have low precision, poor anti-interference ability, complex operation, high power consumption, and it is difficult to realize automatic measurement and use as a portable device; in the process of liquid impedance measurement, traditional The measuring instrument needs a large volume of electrodes, electrode fixtures, measured liquid containers, and test racks to be combined and operated correctly to perform impedance measurement, which makes the measurement process complicated. If there is a problem in one link, the test result will be inaccurate.
