Description
Product introduction
In industrial facilities handling combustible gases, reliable detection is a key part of the fire-and-gas protection strategy. The Det-Tronics EQ21OOCG is identified as an infrared point gas detector for monitoring combustible hydrocarbon gases. Infrared sensing can distinguish gas absorption characteristics and is used in industrial environments where gas detection must remain dependable under changing ambient conditions.
When procuring the Det-Tronics EQ21OOCG, verify the full model designation, approved gas calibration, output and wiring arrangement, and compatibility with the installed Eagle Quantum Premier system. Do not assume that every EQP detector shares the same electrical interface or certification.

Application scenarios
- Process plants: Detection of combustible hydrocarbon gas leaks around process equipment.
- Oil and gas facilities: Gas monitoring in areas where hydrocarbon releases may create a fire or explosion hazard.
- Fire-and-gas safety systems: Integration into a compatible detection and alarm architecture.
- Maintenance of installed systems: Replacement of a detector while retaining the existing system design, subject to compatibility checks.
Field engineering note: Gas detectors are safety-related instruments. Before returning a replacement to service, confirm detector addressing and wiring, verify calibration using the prescribed test gas, and complete the site’s required functional test.
Related product identification
The EQ21OOCG is associated with the Det-Tronics Eagle Quantum Premier family. Other detectors in that family should not be treated as direct substitutes without checking their sensing technology, supported gases, system interface, certifications, and configuration.
Engineer’s replacement checklist
- Match the complete model code and product nameplate.
- Verify gas type, calibration range, supply, outputs, and system compatibility.
- Check hazardous-area approvals and complete the manufacturer’s calibration and functional tests.
Frequently asked questions
1. What is the EQ21OOCG?
It is listed as a Det-Tronics infrared point gas detector used for combustible-gas monitoring.
2. Which gases can it detect?
It is associated with combustible hydrocarbon detection. Confirm the exact gas list and calibration range for the installed configuration.
3. Is it part of the Eagle Quantum Premier system?
Parts references associate it with the EQP family. Verify the system interface and configuration against the installed equipment documentation.
