Martindale's AV90 is a dual capability anemometer that can be used to measure both the windspeed passing through the instrument's large vane and also the overall temperature of the air at the same time. It's built for use in HVAC and other similar applications, and the tester is easy to use, portable and comes equipped with a vane with long lead.
When measuring overall wind velocity the AV90 allows users to measure in five different ranges: 0.3 to 30m/s, 60 to 5900ft/min, 0.6 - 58 knots, 0.7 to 67mph and 1.1 to 108km/h. When used to measure temperature this anemometer features measurement range of -20 to 60°C (-4 to 140°F).
During both measurement modes the AV90 allows users to calculate minimum and maximum values, and can also be used to take 8 measurements over a time period with the overall result being an average of these parameters. Time scales are also adjustable, and users can select readings every two seconds up to every sixteen seconds.
