Alphasense PID Sensors Photoionisation Detectors monitoring of Volatile Organic gas analyzers environmental Sensor

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • VOC Detection via PID Technology: Equipped with Photoionization Detection (PID) sensors, these devices accurately measure volatile organic compounds (VOCs) and other gases across a wide range (e.g., 0–20 ppm to 0–4000 ppm), enabling precise environmental or industrial monitoring.
  • Safety-Certified for Hazardous Environments: Designed with certifications like ATEX and UL22, ensuring compliance and safety in explosive atmospheres or high-risk industrial settings.

Key features

  • 1. Material Technology

    • With a corrosion-resistant metal body, ensure reliable operation in harsh industrial environments* compared to plastic-bodied sensors.

  • 2. Interactive Design

    • With a pin mounting design, easily integrate into existing systems or tight spaces, saving installation time versus bulkier alternatives*.

  • 3. Performance Parameters

    • With customizable detection ranges (0–20 ppm to 0–4000 ppm), adapt to diverse monitoring needs—20x broader range flexibility than fixed-sensor models*.

  • 4. Scenario Solutions

    • Certified for use in ATEX and UL22-rated hazardous environments, enabling safe deployment in explosive atmospheres where non-certified devices cannot operate*.

  • 5. Certification Standards

    • Meet ATEX and UL22 safety certifications, ensuring compliance with global industrial standards—unlike uncertified competitors*.

Product details

Alphasense PID Sensors Photoionisation Detectors monitoring of Volatile Organic gas analyzers environmental Sensor

Alphasense PID Sensors are advanced Photoionisation Detectors (PID) designed for precise monitoring of Volatile Organic Compounds (VOCs) and other gases in industrial, environmental, and safety-critical applications. Equipped with durable cylindrical bodies and certifications like ATEX and UL22, these sensors ensure reliable performance in harsh environments. The pin-mounted design allows for easy integration into monitoring systems.

Supplier's note

  1. Three Technical Breakthroughs:

    • Dual Certifications (ATEX + UL22): Enable deployment in global hazardous zones.
    • Extended Range (0–4000 ppm): Pro Model detects VOCs in high-concentration industrial environments.
    • PID Sensitivity: Detects VOCs as low as 0.1 ppm, outperforming traditional sensors.

  2. Version Selection Guide:

    • Base Model (PID-AY): Ideal for low-concentration environments (e.g., office air quality checks).
    • Advanced Model (PID-AH): Perfect for mid-range industrial safety monitoring (e.g., chemical plants).
    • Pro Model (PID-AR): Best for heavy-duty applications like oil refineries, where high-range detection and IP67 waterproofing are critical.

With the Pro Model’s triple-industry-standard chemical resistance, you can safely handle corrosive gases while its rapid 1-second response ensures real-time alerts. Pair this with IP67 durability, and you achieve uninterrupted operation in extreme conditions.
