CROSH has partnered with the Greater Sudbury Public Library to make the Aranet4 CO² monitor available to the public with the purpose of bringing awareness to air quality and ventilation.
The device is suitable for monitoring the CO² level at home, in school, office, or in any other indoor
environment.

We partnered with the City of Greater Sudbury to loan Kill-a-Watt meters to help reduce energy usage.
Kill-a-Watt meters are energy monitoring devices. They can be plugged into individual appliances to calculate the amount of electricity used during a specific time period.
