Kestrel Belt Clip Case

For compatible Kestrel® Pocket Weather Meters.

The Kestrel 4200 provides automatic humidity ratio readings as well as measuring relative humidity, dewpoint, wet bulb temperature, and heat stress index. The patented dual chamber humidity sensor ensures fast, accurate readings in any environment. This versatile instrument also measures current, average, and maximum air velocity; volume air flow; temperature in °F or °C; barometric pressure; altitude; and wind chill. Combine the Kestrel 4200 with a portable vane mount and portable tripod (each sold separately) for a data-logging weather station that rotates in even the slightest breeze and is ideal for short-term monitoring. The Kestrel 4200 shows results on a multi-function three-line backlit display, stores 1,600 data points, is waterproof, and floats. Includes a protective pouch, neck and wrist lanyards, and 2 AAA batteries. Five-year manufacturer’s warranty. Assembled in the USA.

*Humidity sensor can be recalibrated in the field. Accurate readings may be taken beyond these temperature limits by exposing the unit for the minimum time necessary to take and record measurements.
