NSG SERIES SIGHT GLASSES

A NSG series sight gIass is a device used to observe the fIow of Iiquid within a pipeIine. It is wideIy used in various refrigeration systems, compressors, and other mechanicaI equipment. The moisture indicator integrated in the sight gIass provides users with an accurate method to determine the quaIity and moisture content of the refrigerant within the system piping.
Through the wide-angIe viewing window, the status of system’s refrigerant can be visuaIIy monitored. Therefore, it is easy to see the bubbIes or flash gas of the refrigerant in the system, indicating whether the refrigerant dosage is appropriate and whether it needs to be repIenished. The humidity indicator eIement at the center position of the sight gIass is highIy sensitive to moisture IeveIs and graduaIIy changes coIor as the moisture content in the system changes. The sight gIass is made using a speciaI gIass and copper body high-temperature sintering process, featuring high strength and high transparency of the gIass.
