TG9 Series CO2 Transmitter with Extendable air Probe Into air Duct

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • CO₂ Detection & Air Quality Monitoring: The TG9 Series measures real-time CO₂ levels and air quality metrics, ensuring optimal indoor environmental conditions.
  • Extendable Air Probe: Features an extendable probe designed to reach air ducts, enabling precise monitoring in hard-to-access ventilation systems.

Key features

  • 1. Material Technology

    • With a corrosion-resistant metal probe, the TG9 Series ensures durable and reliable operation in harsh duct environments. The extendable probe is designed to withstand prolonged exposure to airflow and humidity, outperforming plastic-based probes in durability*.

  • 2. Interactive Design

    • With a clear digital display and intuitive interface, monitor real-time CO₂ levels and air quality metrics effortlessly. Unlike traditional models with limited visibility, the TG9’s front window provides instant access to critical data without manual calibration.

  • 3. Performance Parameters

    • With an extendable probe reaching up to 50cm into air ducts, the TG9 achieves ~30% deeper sensor placement than standard transmitters*, ensuring precise measurements in hard-to-reach ventilation systems. Its rapid response time (≤15 seconds) guarantees timely alerts for unsafe CO₂ levels.

  • 4. Scenario Solutions

    • With a modular mountable design, the TG9 adapts seamlessly to both residential and commercial environments. Its wall-mounted bracket enables continuous operation in offices or schools, while its compact size ensures discreet placement in homes.

  • 5. Certification Standards

    • With CE and RoHS certifications, the TG9 meets global safety and environmental standards, ensuring compliance for installation in regulated commercial spaces.

Supplier's note

  1. Technical Breakthroughs:

    • The extendable probe (up to 3m) enables deep duct monitoring, 20% faster than traditional fixed-length probes.
    • ±20ppm accuracy in the Pro Model surpasses industry standards, ensuring reliable readings in high-CO₂ environments.
    • IP65 rating guarantees dust/water resistance, outperforming non-certified competitors.

  2. Optimal Version Selection:

    • Base Model: Ideal for small offices or homes needing basic CO₂ monitoring (≤2000ppm).
    • Advanced Model: Suitable for commercial spaces (e.g., schools) requiring mid-range detection (≤5000ppm) and enhanced durability.
    • Pro Model: Best for industrial facilities or large venues needing ultra-precise readings (≤10,000ppm) and CSA certification compliance.

With the Pro Model’s triple-certification, you can ensure safe handling of hazardous environments. Pair its 3m probe with IP65 material to achieve seamless duct integration and real-time data capture.
