1. Product Overview
YGM203 is a  Air speed transmitter. According to the different needs of users under different working conditions, we provide users with a variety of choices. First of all, the product shell can be made of metal cast aluminum shell and industrial plastic. The metal cast aluminum shell is more convenient for users to use under worse working conditions, and its structure is more stable; The plastic shell can be used with LCD to provide users with intuitive test results; In addition, we also provide two different product installation methods: integrated and split; And three kinds of sampling probe rods: stainless steel probe rod, diamond shaped averaging probe rod and detachable diamond shaped averaging probe rod for users to choose independently.
