For the past years we are grateful for all the support shown for our CO2 sensors, VC1008T series and VC1008F series. We had feedbacks from our industries with regards to the installation and testing process of VC1008F series. Hence, we have decided to improve the housings of our CO2 sensors to one that could ease the installation and testing process and also satisfy both US and the European mounting standards. Our new improved series are VC2008T and VC2008F. Do visit our webpage for more information and we would appreciate all your comments.
