Device Helps Monitor Heat Stress Levels of Employees

Heat stroke is a serious health risk to workers wearing heavy protective clothing or who are involved in strenuous activity. Heat challenges the body’s ability to control its internal temperature, especially in those suffering from heart disease, asthma, diabetes or obesity. More than 400 Americans die of heat stroke every year.

To combat this risk Casella CEL offers the Microtherm heat stress monitor. This simple-to-use, handheld device displays in real-time the Wet Bulb Globe Temperature (WBGT) index, the internationally recognized method of calculating heat stress. By displaying real-time changing WBGT values the Microtherm empowers managers to make pre-emptive safety decisions before an employee is feeling the effects.

The Microtherm calculates WBGT by means of three sensors manufactured to BS 1904 and DIN 43760 accuracy standards. Sensors can be mounted directly on the instrument itself or remotely positioned by cable up to 30 feet away, indoors or outdoors. The Microtherm’s data-logging capabilities record date and time, along with the measured and computed values. Logging intervals can be set anywhere from 30 seconds to one hour with results shown in either Fahrenheit or Celsius.

Included with the Microtherm is a Microsoft Windows 32-bit PC software package (Win HSM) for data collection and analysis. The software produces graphical and tabular reports that are easily imported into other applications. Summary and WBGT Heat Stress Index reports can also be generated.
