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 (PM?, PM?.?, PM??), NO?, O?, CO and SO?. Additional important air pollutants such as NO, CO? and H?S 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 (O?), nitrogen dioxide (NO?), nitrogen monoxide (NO), carbon monoxide (CO), carbon dioxide (CO?), sulfur dioxide (SO?), and hydrogen sulphide (H?S). The PM module, available only for the DF-5, enables simultaneous measurements across multiple PM size channels for accurate PM (PM?, PM?.? and PM??) monitoring.
