MODEL# PGM-2500, PGM-2560

  • Provides monitoring of Oxygen (O2), Combustibles (LEL), and toxic gases.
  • Toxic gas options include Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Sulfur Dioxide (SO2) and Hydrogen Cyanide (HCN).
  • Available in Diffusion or Pumped version.
  • Continuous datalogging (3 months for 4 sensors at 1-minute intervals, 24/7)
  • Easy access to pump, sensors, filter and battery compartment.

QRAE 3 is a wireless compact monitor for one to four gases.

The QRAE 3 provides detection and monitoring of Oxygen (O2), Combustibles, and toxic gases that include Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Sulfur Dioxide (SO2) and Hydrogen Cyanide (HCN). QRAE 3 can deliver wireless real-time instrument readings and alarm status 24/7. This provides better incident visibility and can improve response time.
