PRODUCT DESCRIPTION

Honeywell Midas Toxic Gas Detector

The MIDAS gas detector uses sensor technology to detect a wide range of toxic and flammable gases present in a plant. It monitors points up to 100 feet (30 meters) away, using patented technology to regulate the flow rate and ensure fault-free gas detection. Built with Honeywell’s advanced robotics, the MIDAS gas detector delivers outstanding quality and reliability.

Gases:

  • NH3, AsH3, BCl3, BF3, Br2, CO2, CO, Cl2, ClO2, B2H6, H2SiCl2, CH2F2, Si2H6, F2, GeH4, C4F6, H2, HBr, HCl, HCN, HF, H2S, CH4, CH3F, NO, N2O, NO2, NF3, C5F8, O2, O3, PH3, SiH4, SO2, TEOS, WF6
