REED Instruments Indoor Air Quality Meters (also known as IAQ meters) monitor a number of factors including carbon dioxide, temperature and humidity. REED portable IAQ meters are used every day to monitor environmental conditions in schools, office buildings, factories and hospitals. If you're looking to monitor an environment for an extended period of time, the SD-9901 can be mounted on a tripod and set up to datalog based on a user's sampling frequency.
All REED Indoor Air Quality Meters are backed by a 1 year manufacturer's warranty.
