Certified explosion-proof design ensures safe operation in hazardous areas.

Explosion-proof level:
Ex d ib II C T4 Gb

Multi-Mode Alarm System

When gas concentration exceeds preset limits, the detector activates:

  • Audible alarm (>90 dB)

  • LED flashing light

  • Vibration alarm

These alerts help operators respond quickly to dangerous gas conditions.

4 Gas Detection Capability

The Instrava portable 4 gas detector can simultaneously monitor four common industrial gases.

GasFunction
Combustible Gas (Ex)Detects flammable gas leaks
Oxygen (O₂)Monitors oxygen deficiency or enrichment

A 4 gas detector is designed to simultaneously monitor four common hazardous gases found in industrial environments. Most standard configurations detect:

  • Combustible gases (Ex / LEL)

  • Oxygen (O₂)

  • Carbon monoxide (CO)

  • Hydrogen sulfide (H₂S)

This combination covers the majority of gas hazards in industries such as oil and gas, mining, chemical plants, and confined space operations.

Portable 4 gas detectors are widely used in environments where multiple hazardous gases may be present. Typical applications include:

  • Oil and gas facilities

  • Mining and underground operations

  • Confined spaces such as tanks, tunnels, and pipelines

  • Chemical processing plants

  • Industrial maintenance and safety inspections

In these environments, a personal 4 gas detector helps protect workers by continuously monitoring gas concentrations.

When gas concentrations exceed preset limits, a 4 gas detector activates multiple alarm methods to ensure operators are immediately alerted. These alarms usually include:

  • Audible alarm (buzzer)

  • Flashing LED light

  • Vibration alert

The combination of sound, light, and vibration alarms ensures warnings are noticed even in noisy or low-visibility industrial environments.

Most portable 4 gas detectors use rechargeable lithium batteries designed for long working hours. A typical industrial model can operate up to 18 hours continuously after a full charge.

Long battery life ensures reliable performance during extended field inspections, maintenance tasks, and confined space monitoring.

Yes. Many industrial 4 gas detectors are designed with explosion-proof certifications for use in hazardous areas where combustible gases may be present.

These detectors often comply with standards such as ATEX, IECEx, or CCCF and include explosion-proof ratings like Ex d ib II C T4 Gb, ensuring safe operation in potentially explosive atmospheres.

A high-quality industrial 4 gas detector should include several key features to ensure safety and durability:

  • IP-rated dust and water protection

  • Explosion-proof certification

  • Multiple alarm systems (sound, light, vibration)
