Low Annual Operation Cost
The PureAire Acrylonitrile Gas Monitor has the lowest annual maintenance costs of any gas monitoring system on the market. PureAire’s renewable sensor cells are easily recharged with electrolyte right in the field at approximately 20 % of the cost of disposable sensor cell-type systems. Recharge costs typically run about $35.00 per sensor every 6 months. Combined with our built-in, low-power pyrolizer and long-life sample pump, the monitor will lower your annual operation costs. When compared to competitive gas monitors, it will pay for itself in just a few years.

Connects to DCS and PLC Controls
The PureAire Acrylonitrile Gas Monitor transmits continuous gas concentration levels to any distributive control system, programmable logic controller, or PureAire’s proprietary single and multichannel controllers. The Monitor can be operated remotely up to 1,000 meters, 0.6 miles from centralized distributive control systems.

A toxic gas detector continuously monitors the air for harmful gases, including carbon monoxide, chlorine, ammonia, and hydrogen sulfide. It warns personnel before levels reach dangerous concentrations. Toxic gas detectors protect workers from low-level poisonous gases (in the ppm range) that can cause immediate or long-term health effects.

The most common include:
• Carbon monoxide (CO) – parking garages, boiler rooms
• Hydrogen sulfide (H₂S) – oil & gas, wastewater treatment
• Chlorine (Cl₂) – water treatment, chemical plants
• Ammonia (NH₃) – refrigeration, food processing
• Nitrogen dioxide (NO₂) – vehicle maintenance facilities
• Sulfur dioxide (SO₂) – power plants, refineries
• Ozone (O₃) – semiconductor, pharmaceutical industries
• Refrigerant gases (classified as A1, A2L, B2L, A3) – HVAC systems, supermarkets, cold storage, data centers

• Electrochemical sensors: Accurate, low-level detection; best for most toxic gases (CO, H₂S, Cl₂, NH₃).
• PID (Photoionization Detectors): Detects volatile organic compounds (VOCs) and low-level hydrocarbons.
• NDIR (Non-Dispersive Infrared): Used more often for CO₂ or gases that absorb infrared light. NDIR sensor cells are highly effective for detecting refrigerant gases across classifications A1, A2L, B2L, and A3.

• CO: 0–100 ppm, 0–1,000 ppm
• H₂S: 0–30 ppm, 0–200 ppm
• Cl₂: 0–1 ppm, 0–3 ppm, 0–10 ppm, 0–50 ppm, 0–200 ppm
• NH₃: 0–75 ppm, 0–100 ppm, 0–200 ppm, 0–300 ppm, 0–1,000 ppm
• NO₂: 0–2 ppm, 0–9 ppm, 0–15 ppm, 0–20 ppm
• SO₂: 0–15 ppm, 0–20 ppm
• O₃: 0–0.3 ppm, 0–1 ppm, 0–3 ppm, 0–300 ppm
• Refrigerant gases (A1, A2L, B2L, A3 classifications): 0–500 ppm, 0–1,000 ppm, 0–5,000 ppm

• Oil & gas: H₂S monitoring in drilling and refining
• Water/wastewater treatment: Chlorine and H₂S detection
• Food & beverage: Ammonia refrigeration monitoring
• Laboratories & pharma: VOC and toxic gas detection
• Manufacturing & automotive: CO and NO₂ monitoring
• Power generation: SO₂ monitoring in flue gas areas
• HVAC, supermarkets, cold storage & data centers: Refrigerant leak monitoring (A1, A2L, B2L, A3 gas classifications)

Consider:
• The specific gas hazards in your facility
• Sensor type (electrochemical, PID, NDIR, etc.) based on gas and concentration range
• Installation environment (indoor, outdoor, temperature/humidity conditions)
• Compliance needs (OSHA, IFC, local codes)
• Integration with alarms, PLCs, or cloud monitoring systems like PureAire’s CloudConnect

• Electrochemical sensors: Every 6–12 months
• PID sensors: Every 3–6 months
Always follow the manufacturer’s recommendation and perform bump tests for safety.

• LEL: Percentage of gas concentration at which ignition becomes possible. Combustible detectors typically measure 0–100% LEL.
• PPM (parts per million): A finer measurement, usually used for toxic gases rather than combustibles.

Yes, in most cases. Some gases, such as hydrogen sulfide (H₂S), carbon monoxide (CO), and ammonia (NH₃), pose toxic risks at very low concentrations (ppm levels) and combustible risks at higher concentrations (% LEL).
• A toxic gas detector is needed to protect worker health by alarming at ppm exposure limits set by OSHA and other agencies.
• A combustible gas detector is needed to prevent explosions or fires when gas levels approach the Lower Explosive Limit (LEL).

Since the alarm thresholds and sensor technologies differ, a single detector usually cannot provide both types of protection. Many facilities use both toxic and combustible gas detectors for full coverage, often integrated into a single safety system.  This system can activate building ventilation and advanced warning systems when gas levels reach dangerous concentrations.

If a gas is toxic at low ppm and combustible at higher % LEL, you may need dual detection — one detector set for ppm exposure, another for explosion hazard. Sensor selection depends on whether the primary risk is worker health, explosion, or both.
