A wireless vane anemometer that tracks air velocity (0.6-25 m/s), temperature (-20 to 60C) and relative humidity, streaming live readings over Bluetooth 5.0 to the free REED Smart Series app up to 75m away. Up to six units can be logged simultaneously, with sampling intervals as fast as one second, magnetic backing plus tripod mounting for hands-free setups, and roughly 50 hours of runtime from 4 AAA batteries. This unit ships with an included NIST-traceable calibration certificate.
