Details: Our germane gas detector delivers precise, real-time monitoring of this highly toxic semiconductor gas. With rapid detection speed and accuracy, this monitor safeguards your workplace while ensuring compliance with OSHA's Permissible Exposure Limit (PEL) of 0.2 ppm and NIOSH's Recommended Exposure Limit (REL) of 0.2 ppm. The system features adjustable alarm levels and prominent visual and audible alerts to warn personnel of hazardous germane concentrations before approaching dangerous levels.

This germane gas detector is designed for semiconductor fabrication, electronics manufacturing, compound semiconductor production, photovoltaic cell manufacturing, and research laboratories; our detector provides essential protection wherever germane (GeH₄) is handled or stored. The robust construction withstands harsh industrial environments while delivering the critical early detection necessary to prevent dangerous exposure incidents that can lead to severe respiratory damage, kidney damage, and potential fire hazards. 

Included: Germane Gas Detector, belt clip, sling, User manual, USB charging cable, calibration cover, and certified calibration certificate.
