Description

Technical Field

[0001] The utility model relates to the field of moisture content measuring instruments, in particular to a portable grain moisture content measuring instrument. Background Art

[0002] The portable grain moisture meter is an instrument used to quickly, easily and accurately measure the moisture content in grains. This instrument usually uses the principle of capacitance or resistance to deduce its moisture content by measuring the electrical properties of grains. When using it, in order to ensure the accuracy of the measurement results, the metal probe of the instrument should be inserted into the grain to make full contact with the grain.

[0003] Since one end of the metal probe of the measuring instrument is pointed, there is a risk of stabbing people around when carrying it. For example, the existing multi-parameter online moisture content measuring instrument with application number CN202023146447.X requires you to always pay attention to the position of the tip of the metal probe when carrying the measuring instrument, which will eventually cause certain inconveniences in carrying the measuring instrument. Therefore, improvements are made to it. Utility Model Content
