Gastec GOMC-3A Multiple gas detector

Gastec GOMC-3A Multiple gas detector one unit performs three roles, realizing highly efficient and safe control at the same time. Can simultaneously measure three gases: oxygen, a flammable gas, and carbon monoxide.

GASTEC Detector indicate concentrations directly by way of a calibrated scale printed on the tubes. At GASTEC, we endeavour to achieve highest quality detector tubes for analysing airborne gases/vapours, as well as pollutants in soil and water through our advanced state-of-the-art research and development. Through our efforts we have acquired a solid reputation among our customers in virtually all sectors of industry, commerce and society.

Function

Triple-Gas Simultaneous Protection: Tracks ambient concentrations of oxygen ( $\%\text{ }\text{O}_2$ ), flammable hydrocarbons ( $\%\text{ LEL}$ ), and toxic carbon monoxide ( $\text{ppm CO}$ ) on a single screen.
Pre-Entry & Breathing Zone Monitoring: Combines galvanic cell, catalytic combustion, and electrochemical sensors for hazardous zone screening via diffusion or remote sampling accessories.

Features

Multi-Stage Hazard Alarms: Sounds high-decibel audible buzzers and flashes bright LED indicator arrays when gas limits breach OSHA/NIOSH threshold values.
Flexible Sampling Modes: Functions as a wearable personal diffusion monitor or pairs with an external motorized pump and extension line for pre-entry testing.

Applications

Triple-Hazard Confined Space Pre-Entry: Testing utility vaults, storage tanks, and sewers for simultaneous oxygen displacement, explosive vapors, and carbon monoxide accumulation.
Industrial Maintenance & Turnarounds: Personal breathing-zone protection during boiler inspections, furnace servicing, and chemical process piping work.
Emergency Response & Plant Safety Audits: Rapid site screening following gas leaks or suspected combustion hazards.
