Heat Stress Meters

Reads relative humidity, air temperature, dew point, wet bulb globe temperature, and black globe temperature. Records data onto standard SD memory cards.

The Kestrel 5500 is a handheld, compact and robust environmental meter and data logger that has distinct monitoring functions for wind direction using a digital compass.

The Kestrel 5400 Heat Stress WBGT Meter measures widn speed, air flow, ambient temperature, relative humidity and pressure. Replaces the discontinued Kestrel 4400/4600.

Great for construction, pouring concrete, balancing HVAC systems, and spraying crops.

- Waterproof with data logging
- Evap. rate, air Flow, Delta T & air density
- Connects to your smartphone 100 feet away!

Measure heat stress in the field with this light-weight WBGT Heat Stress Meter.

Smart Heat Stress Detector that measures Wet Bulb Globe Temperature (WBGT), Thermal Work Limit (TWL), Globe Temperature and Dry Bulb Temperature.

The Kestrel 5100 is a handheld, compact and robust environmental meter and data logger that has distinct monitoring functions for Measures moisture content ( water grains), Air density and Relative air density (RAD)., ideal for monitoring motor engines in any weather condition. This model has the LINK feature installed.

The Kestrel 5500FW Fire Weather Meter is a hand-held, all-in-one, weather meter that not only measures weather parameters such as temperature, humidity, wind speed and wind direction, but also measures PIG and FDFM.

The Kestrel DROP D3FW Fire Weather Monitor is a handy data logger that can be deployed in seconds to begin capturing data from the start of the fire. Measures temperature, relative humidity, heat stress index, dew point temperature, density/altitude and station pressure.

The Kestrel 5700 Elite is a handheld, compact and robust weather meter, data logger and ballistics solver and database in one. Kestrel 5700 Elite employs the Applied Ballistics bullet library of custom drag models to determine the exact measurement of your bullet's drag profile plus corrections for other factors such as aerodynamic Jump and Spin Drift. In addition, the Kestrel 5700 Elite can measure 14 total meteorological parameters measured, calculated and displayed real-time and stored in memory. The optional vane mount allows the Kestrel 5700 Elite to measure wind speed and wind direction.

Smart Heat Stress Detector that measures Wet Bulb Globe Temperature (WBGT), Thermal Work Limit (TWL), Globe Temperature and Dry Bulb Temperature.
