1. Product Overview
YGM209 special differential pressure display instrument for clean room is an integrated product based on analog signal input, with display and analog output or 485 output functions. A good LCD window displays the current differential pressure value, and has on-site audible and visual alarm function. The product has the advantages of high precision, stable performance, strong reliability, convenient installation, etc. The stainless steel panel is more solid and reliable, and is widely used in industrial environments such as clean workshops.
