Sensor Tube

The Sensor Tube DF-4/DF-5 is designed for air monitoring applications in locations without power supply source but requiring elongated monitoring period without interruption. The Sensor Tube DF-4/DF-5 has large capacity internal battery and specially designed data transmission cycle with minimum system power consumption.
  • Modular design with configurable parameters across all model variants
    Sensor Tube can measure criteria air pollutants including particulate matter (PM₁, PM₂.₅, PM₁₀), NO₂, O₃, CO and SO₂. Additional important air pollutants such as NO, CO₂ and H₂S are available as optional measurements.
  • Remote calibration capabilities and flexible data transmission options
    The Sapiens SEIN platform offers a calibration function, which is a powerful and unique tool for quality control and assurance. This function integrates Sapiens Sensor's unique hardware capabilities.
  • Light weight and compact design with ultra-low power consumption
    Light weight and compact design for versatile installation options of tripod, wall mount and crossarm. The ultra-low power consumption enables the Sensor Tube to operate using its internal battery or with a solar panel.
  • Calibration and Validation
    1) Factory calibration: Every Sapiens Sensor device is factory pre-calibrated before shipping. 2) Lab calibration: Devices can be sent to the Sapiens Sensor Care Service Centre for NIST-traceable factory calibration. 3) Field calibration: A Humidified Multi-Point (HMP) portable calibrator, along with calibration gas cylinders, can be used for field calibration. 4) Collocation calibration: Devices can be collocated at or near an Air Quality Monitoring Station (AQMS) to facilitate remote collocation calibration.
    Efficient Project Management & Device Management
    SEIN is Sapiens’ exclusive online platform for managing accounts, projects, and devices, as well as accessing real-time data collected by the sensor network. The platform provides a comprehensive set of features tailored to meet the needs of project managers, sensor users, quality control managers, and data analysts.

    Sensor Tube DF4/DF5
    The Sensor Tube DF-4/DF-5 is designed for air monitoring applications in locations without a power supply, allowing for extended monitoring periods without interruption. It supports up to four gas modules, which can be configured at the time of purchase, including ozone (O₃), nitrogen dioxide (NO₂), nitrogen monoxide (NO), carbon monoxide (CO), carbon dioxide (CO₂), sulfur dioxide (SO₂), and hydrogen sulphide (H₂S). The PM module, available only for the DF-5, enables simultaneous measurements across multiple PM size channels for accurate PM (PM₁, PM₂.₅ and PM₁₀) monitoring.
