The Fluke 975 AirMeter test tool raises indoor air monitoring to the next level by combining five powerful tools in one, rugged and easy-to-use hand-held tool to make indoor air quality testing easier and faster.

It can be used to verify the operation of building HVAC control systems, determine whether adequate ventilation exists in an area, monitor air flow and velocity, test for dangerous carbon monoxide leads and perform duct traversals.

The Fluke 975 can simultaneously measure, log and display temperature humidity, CO2 and CO on a bright backlit LCD display. One-touch air flow and velocity measurements can be taken with the available probe included with the 975V velocity kit option.

There is a Min/Max/Average function on all measured and calculated readings and the display has a metric or standard units option. Additional features of include audible and visual threshold alarms, extensive discrete or continuous data logging capacity, downloadable to PC via a USB interface and a keypad lock for security.
