Lutron WBGT-2010SD heat stress meter for working conditions

The Lutron WBGT-2010SD heat stress meter measures indoor and outdoor wet bulb globe temperature (WBGT) values, black globe temperature, humidity, air temperature, wet bulb temperature and dew point and is designed for objective assessment of working conditions in extreme weather.

Objective criteria for determining appropriate levels of outdoor physical activity can be valuable for manual labour in industrial situations, as they provide clear parameters for appropriate action. The US military developed the WBGT basis for their training camps, and it has since become widespread for workplaces and sports activities. The WBGT Index is useful for providing guidelines for work breaks and restrictions on intense activity.

Temperature and dew point values can be read on the device’s display and logged to SD card memory. An audible alarm attracts attention if conditions change.

Data can be logged automatically in real time at intervals from 1 to 3600 s with unlimited records or manually, by button press, to 99 readings. This means any decisions made on activity can be backed up by factual evidence of environmental conditions at a given time. The SD card can be transferred to a PC and data analysed and saved using a standard spreadsheet program.
