INTRODUCTION

Why CO ?
2
Associations of higher indoor carbon dioxide (CO2) concentrations with impaired work performance
and increased health symptoms.
Swiss sensor technology
The device comes with Swiss made SENSIRION CO2 sensor SCD series designed for indoor air quality
application. This sensor builds on the photoacoustic sensing principle and Sensirion's patented
technology, which enables precise measurements from the device's first operation and throughout its
lifetime of usage.
Multi-zone feature
Through our multi-zone technologies, each device has a unique device code with a user selectable
channel number. Up to 4 separate air quality sensors can be placed in an open proximity covering an
area across 100m radius from its main display unit (to be purchased separately).
Low maintenance
The Swiss sensor is expected to have a lifetime of over 10 years while operating continuously for 24
hours/day. With its simple structure, there is no need for cleaning and/or maintenance, thus avoiding
problems related to sensor drift or malfunction.
