Explosion-Proof
Gas Detection

Explore certified explosion-proof gas monitors approved for use in Class I hazardous environments.

Intrinsically Safe
Gas Detection

Explore low-energy MSHA, IECEx / ATEX certified gas detection approved for use in classified areas.

General Purpose
Gas Detection

Explosion-Proof
Gas Detection

Safeguard Class I explosive atmospheres from ignition with certified explosion-proof gas monitors.

Our line of explosion proof gas monitors are engineered for industrial environments and approved for use in Class I hazardous environments by IECEx and ATEX. Using heavy-duty NEMA 7X explosion-proof enclosures traps ignition, sparks, arcs, or explosions inside the housing. Explosion-proof housing provides high-energy electrical support without restricted energy levels to permit high voltage sensors to operate in industrial areas. Explosion-proof gas monitors support critical infrastructure across oil and gas operations, refineries chemical processing plants, mining and other industrial facilities with hazardous atmospheres.

Optio™ XP

Explosion-Proof Multi-Gas Monitor

Supports up to 6 internal or remote gas sensors in Class I, Zone 1 hazardous locations, with wireless configurations available.

CX Series

Explosion-Proof Gas Monitor

Detects a single toxic or combustible gas in Class I, II, and III hazardous locations with an internal or remote sensor.

Intrinsically Safe
Gas Detection

Certified low-energy gas monitors approved for use in classified environments.

Our line of intrinsically safe gas monitors limit electrical and thermal energy below ignition thresholds, and are certified for use in Class I hazardous locations by IECEx, ATEX, or MSHA (where applicable). Intrinsically safe gas detection gives operations the benefit of live maintenance, calibration, and diagnostics of our gas monitors without requiring gas clearance and scheduled downtime. These monitors provide effective cost saving benefits that permit the use of conventional cable runs, simpler enclosures while avoiding costly operational interruptions.

Optio™ IS

Intrinsically Safe Multi-Gas Monitor

Approved by ETL-US, cETL, ATEX, and IECEx for hazardous locations, supporting up to 6 sensors for fixed multi-gas detection.

Optio™ G

MSHA-Approved Multi-Gas Monitor

Certified to detect up to 6 different toxic and combustible gases in underground coal mining applications.

General Purpose
Gas Detection

Gas monitors for non-classified industrial and commercial deployment approved and tested to applicable standards.

Our general purpose gas detection is designed for operation in ordinary locations found in industrial, commercial, and mining applications. Designed to support the well-being of workers and facility occupants, our gas detection carries applicable UL 61010, UL 2075, and ULC 588 certifications when required by international and regional standards. Our general purpose gas detection is engineered with the flexibility to meet the needs of any operation.

Optio™ V

Commercial Multi-Gas Monitor

Supports up to 6 internal or remote sensors to monitor toxic CO and NO2 and integrate with building automation systems.

Optio™ PGM

Monitors toxic CO and NO2 in enclosed areas and integrates with facilities using dual onboard relays and analog outputs.

911154-1 CO/VC

Commercial CO Monitor

Stand-alone carbon monoxide controller that can daisy-chain to create a multi-device network with exhaust fan control.

Optio™ G Wireless

Wireless Mutli-Gas Monitor for Mines

Engineered for flexibility in non-hazardous underground applications, with wireless power and communications for up to 6 sensors.

Optio™ B

Lithium-ion Battery Multi-Gas Monitor

Detects CO2, H2, CH4, CO, and VOCs from Li-ion battery off-gassing to identify early thermal runaway.

Optio™ BGM

Lithium-ion Battery 3-Gas Monitor

Detects CO2, H2, and VOCs from Li-ion battery off-gassing to identify thermal runaway before visible smoke or flame appears.

CN Series

Toxic Gas Monitor

CS0352-MP

Dual-Probe Aspirated Gas Monitor

Dual-probe system samples CO and O2 for detection in high-temperature, high-humidity, and other challenging environments.

Frequently Asked Questions

What gases can your detection systems monitor?

Conspec gas detection systems are available for monitoring a variety of toxic, combustible, and oxygen-deficiency hazards, including:

Carbon Monoxide (CO)Methane (CH4)
Hydrogen (H2)Hydrogen Sulfide (H2S)
Nitrogen Dioxide (NO2)Carbon Dioxide (CO2)
Oxygen (O2)Chlorine (Cl2)
Ammonia (NH3)Ozone (O3)
Nitric Oxide (NO)Propane (C3H8)
Hydrogen Cyanide (HCN)Hydrogen Chloride (HCl)
Volatile Organic Compounds (VOCs)Sulfur Dioxide (SO2)

Additional gas configurations are available. Contact Conspec for a complete list of available sensor options and part numbers.

What is the difference between a multi-gas monitor and a single-gas monitor?

The difference between a multi-gas monitor and a single-gas monitor is the number sensors they support. Our single-gas monitors support a single gas sensor for focused detection applications, whereas our multi-gas monitors support up to 6 sensors for more complex hazard detection.

How many sensors can an Optio-series multi-gas monitor support simultaneously?

Many of our multi-gas monitors can support up to six sensors per device, but the support varies based on model. We offer a variety of multi-gas solutions to suit facilities of all sizes and challenges, including dual-gas (Optio PGM) and 3-gas (Optio BGM) monitors.

Can your gas monitors withstand harsh environmental conditions?

Yes. Conspec gas detectors are available in a wide range of enclosure options, certifications, and approvals designed to meet the demands of challenging industrial environments.

Our product lineup includes solutions with:

  • MSHA-certified designs for underground mining applications
  • Intrinsically safe certifications, including IECEx and ATEX approvals
  • Explosion-proof enclosures for Class I, Zone 1, and Division 1 hazardous locations
  • Weather-resistant and corrosion-resistant options for harsh outdoor environments

Conspec products undergo rigorous testing and certification through recognized third-party organizations, including Intertek, Nemko, and UL, to verify compliance with industry standards. Where applicable, our systems also support additional local certifications and approvals required for specific industries and operating environments. Visit an individual product page to view a complete list of available certifications and approvals.

Can your gas monitors be integrated into existing safety systems?

Conspec will evaluate your existing safety infrastructure to determine the best approach for integrating gas detection into your current system. Our products are designed with flexible communication options to support a wide range of control, monitoring, and building management platforms.

Depending on the product and application requirements, available communication options may include:

  • Modbus RTU (RS-485)
  • Modbus TCP
  • BACnet
  • Wireless communication options (where applicable)
  • Additional communication protocols and integration methods

We design our systems to provide flexible integration options; however, communication capabilities and available protocols may be dependent on product configuration, certifications, and applicable industry regulations.
