Pengenalan Produk

The carbon dioxide sensor uses non-dispersive infrared absorption to measure CO₂ without consuming a reactive sensing material. Room air diffuses through protected openings into the optical chamber, where wavelength-selective measurement separates carbon dioxide absorption from the reference signal. Temperature compensation and baseline-management options support stable indoor operation. Selectable voltage, current or network outputs let ventilation controls, environmental monitoring and room displays use the same measured concentration.

Ciri-ciri Utama

NDIR optical measurement is selective to carbon dioxide and does not consume electrolyte.

A dual-channel or reference-compensated design reduces long-term light-source drift.

Ventilated wall housing samples occupied-zone air while protecting the optical chamber.

Configurable analog and network outputs support both HVAC control and monitoring.

Kebimbangan Produk Pelanggan

CO₂ measurements are most useful when the sensor sees representative room air and its baseline behavior matches the occupancy pattern.

A sensor near a door or supply diffuser responds to transient air instead of the occupied zone.A stable wall location away from direct drafts provides a more representative room sample.

Automatic baseline correction is unsuitable for continuously occupied spaces.Selectable baseline strategy allows fixed or manually referenced calibration where CO₂ never falls to outdoor levels.

Dust or cleaning spray enters the optical path.Protected diffusion vents and an easy-wipe enclosure reduce direct contamination.

Ventilation controls and monitoring use separate sensors that disagree.Multiple outputs distribute one measured value to both systems.
