The WBGT103 wet bulb globe temperature meter is a very easy-to-use hand-held unit.  The process for determining the WBGT is described in ISO 7243.  The WBGT index was developed to reduce heat stress injuries.  The American Conference of Governmental Hygienists publishes threshold limit values (TLV's) that have been adopted by many governments for use in the workplace.
