AIR/GAS SENSORS: CO, CO2, NO2, HYDROGEN & IAQ
Carbon Monoxide (CO) Transmitter
Applications & Features
It’s necessary to control the ventilation of car park and vehicle maintenance and test work shop according to many building’s HVAC regulations. Considering of energy efficiency, demand controlled ventilation (DCV) is needed to provide enough fresh air according to CO concentration. These transmitters are designed for the control of ventilation system to safety and energy saving operations
Electrochemical sensor gives good long term accuracy, sensitivity and reliability
The sensor has more than 5 years life span to protect customer’s investment, long-term stable performance and low drift, only need periodical recalibration as long as 12 months or more
Digital technology applied, multiple outputs optional, over voltage and reverse polarity protection, high reliability and anti-interference capability
Different housings meet different installation requirements, SCMW is for wall mount with better protection, while SCMWN for general room application
Carbon Dioxide (CO2) Transmitter/Controller
Applications & Features
This series are designed for monitoring & controlling indoor air quality (CO2 concentration)
SCDN/SCDNC is suitable for wall mount and SCDD is suitable for duct mount. SCDD uses a patented probe structure for excellent sampling performance
High performance NDIR digital sensor and circuit, ensure precise measurement and temperature compensation
15 years sensor life without maintenance
Digital technology applied, over voltage and reverse polarity protection, high reliability and anti-interference capability
All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring (for SCDN/SCDNC)
Multiple outputs selection. Stable, reliable and fast response
LCD & function keys can set various parameters, calibrate and adjust output, so the product can be a standalone controller (for SCDNC)
