DESCRIPTION:
The Extech 45158 Mini Thermo-Anemometer with Humidity is a compact yet robust environmental measurement tool designed for airflow diagnostics and ambient condition assessments. Built with a fold-up protective housing that extends for improved reach, this meter simultaneously displays air velocity and either temperature or relative humidity on a large dual LCD screen. It offers selectable averaging intervals, a data-hold function, and automatic shutoff to conserve battery life. The water-resistant, rugged housing is engineered to float and withstand field conditions, while its lightweight design and lanyard make it easy to carry and use in HVAC, meteorology, and facility maintenance applications. 

Key Features:

• Measures air velocity in multiple units including ft/min, m/s, km/h, mph, knots, and Beaufort scale 

• Dual display of air velocity and temperature or relative humidity 

• Measures relative humidity (10 %–95 % RH) and dew point 

• Selectable averaging function (5, 10, or 13 s) for stable readings 

• Fold-up protective housing extends reach to ~229 mm (9 in) 

• Water-resistant housing floats and is drop-tested for field durability 

• Data hold and auto power-off functions 

• Tripod mountable for repeated measurements 

• Supplied with a CR2032 battery and lanyard
