014 Mini by Met One Instruments

The 014mini Wind Speed Sensor is an accurate, durable and economical instrument, designed for use in wind resource assessment. The sensor is identical to the 014A wind speed sensor except that it is intended for mounting on a standard ½” vertical mast and is connected to a data logger using a 22ga, 2-wire conductor. This sensor is ideal where upgrades or replacement of existing equipment is required. The 014mini can be ordered individually calibrated to accepted standards.
