Kestrel 5400 Heat Stress Tracker - Tan

Description

The Kestrel 5400 Heat Stress Tracker is revolutionary in size, cost and capability for those in need of measuring Heat Stress.

Along with having a Wet Bulb Global Temperature reading, the Kestrel 5400 Heat Stress Tracker displays thermal work limit (TWL), another recognized composite heat stress prediction tool. For both WBGT and TWL, the Kestrel 5400 Heat Stress Tracker provides on-screen alarms when conditions enter the caution and danger zones, providing clear and immediate guidance that heat illness prevention steps must be taken. Clothing levels can also be customized, making the Kestrel 4400 particularly useful in activities requiring heavy protective gear which worsens heat stress. The Kestrel 5400 Heat Stress Tracker also displays natural wet bulb temperature, and black globe temperature.

Human heat stress results from a combination of many environmental factors air temperature and humidity along with radiant heat from the sun and surfaces, balanced by the cooling effect of breezes or air flow. Anyone who has stood under welcome shade adjacent to a sizzling parking lot understands that these conditions must be evaluated exactly where people's activities are taking place. The most common composite measurement used to determine appropriate exposure to heat stress conditions is Wet Bulb Globe Temperature or WBGT. The American College of Sports Medicine, the American Conference of Governmental Industrial Hygienists, and the US Military all have published threshold limit values (TLVs) or reference guidelines for conditions, activity levels and hydration based on WBGT, clothing levels and acclimatization of participants.

Reading the WBGT is important even in indoor settings where heat stress is a concern. The Kestrel 5400 Heat Stress Tracker has an indoor setting on the WBGT setting which basically turns off the function of taking into account the direct solar radiation from the sun. Its important to place the Kestrel in a representative area of the conditions that the workers face. Remember, wind plays a factor in WBGT, so a vane mount can be used indoors as well. In the case of a ceiling fan, if the Kestrel doesnt pick up the ceiling fan, then you are essentially getting the worst case WBGT readings which is not actually a bad thing. If the airflow is pretty strong from the fan and you want to have that factored in, you could mount the Kestrel sideways (vs vertical) so the impeller picks up the wind more realistically. You can use the Clamp to achieve this.
