The GIR3000 is an explosion-proof fixed diffusion-type infrared gas detector, specially designed for continuous monitoring of Nitrous Oxide (N₂O). It can also detect combustible gas, carbon dioxide and carbon monoxide. Adopting infrared spectral absorption technology, the sensor features no poisoning risk with a service life over 5 years and a T90 response time less than 6 seconds. It works normally in oxygen-deficient environments. With SIL2 safety rating and non-intrusive calibration design, it ensures safe and convenient maintenance.

Product Advantage

1. Adopts infrared detection principle, free from sensor poisoning, aging and zero drift. Long service life up to more than 5 years, greatly reducing replacement and maintenance costs.

2. Oxygen-independent design, suitable for inert gas and oxygen-deficient working environments, wider application range than traditional catalytic and electrochemical sensors.

3. Ultra-fast response speed (T90 < 6s), can quickly capture gas leakage and trigger alarm to ensure on-site safety.

4. High measuring accuracy and resolution, stably and accurately monitor N₂O concentration changes to meet industrial precision monitoring requirements.

5. Flameproof structure with professional Ex certification, applicable to Zone 0/1/2 explosive hazardous areas, fully compliant with industrial explosion-proof standards.

6. Supports magnetic wand calibration and remote calibration. No need to open the explosion-proof housing during operation, avoiding safety risks and simplifying on-site debugging.

7. Equipped with 4-20mA analog signal, RS-485 Modbus, HART digital communication and multi-channel relay alarm output, convenient to connect with various control systems and realize system networking.

8. Built-in intelligent self-diagnosis system, real-time monitoring equipment operating status, automatically identify and display faults for quick troubleshooting.

9. Backlit OLED/LCD display, clearly show real-time gas concentration, working status, alarm and fault information, intuitive viewing.

10. Passed SIL2 functional safety certification, suitable for high-standard industrial safety monitoring occasions.
