PMTX010008 (PURRMETRIX)

The Purrmetrix data logging system measures, logs and analyses a range of important environmental variables.This wireless CO2 sensor is small and robust, and plugs into a conventional power socket, or can connected to a power supply with a USB extension cable to allow measurement in other locations. Well suited to monitoring air quality for diagnosing problems and auditing compliance. Accuracy of 50ppm or +/- 3% with a resolution of 10ppm. The unit self calibrates to an assumed atmospheric level of CO2 (400ppm) on a 24 hour cycle to avoid the need for user recalibration, with a sample rate of every 30 seconds This is reported to a web service via a gateway unit (Farnell part number 2906732), which is required to collect the data and encrypt it for delivery to the web service. Gateways to sensor have a typical range in a built environment of 40-60M. Purrmetrix CO2 sensors come with a free web service to collect and display environmental data.
