Description
Photoacoustic Spectroscopy CO2 Sensor (PAS CO2 sensor for short) is a cutting-edge product that employs photoacoustic spectroscopy to fulfill the high-end market demand. The sensor modulates light based on Lambert-Beer's law, causing the targeted gas molecules to undergo pulsation and generate acoustic vibrations. These acoustic vibrations at particular frequencies reveal the carbon dioxide levels. Featured with its small size and high precision, the sensor is ideal for detecting varying concentrations of CO2.
Application
HVAC, Air purifiers, Indoor CO2 monitors
Features

Technical Support:
Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory, but the module will be calibrated before leaving the factory.
However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to sales@winsensor.com
