WBGT3200 wet ball baƙar fata ball zafin jiki (WBGT) mai auna lafiya da lafiya a aiki. Saita baƙar fata ball zafin jiki firikwensin, m ball zafin jiki firikwensin, bushe ball zafin jiki firikwensin iya yin filin ma'auni na WBGT a babban zafin jiki wuraren aiki.

WBGT, wanda ake kira wet ball black ball temperature index, shine babban sigogi don kimanta nauyin zafi na jikin mutum wanda ke hulɗa da yanayin aiki.

WBGT ya nuna alamar da ke da alaƙa da metabolism a cikin aiki na musamman na samar da ƙarfin zafi.

WBGT Index ya ƙunshi zafin jiki na ɓangarori uku na Tnw, Tg, da Ta (wani lokaci).

Adadin lissafi kamar haka:

A cikin gida da waje babu hasken rana: WBGT = 0.7Tnw + 0.3Tg

A waje akwai hasken rana: WBGT = 0.7Tnw + 0.2Tg + 0.1Ta

daga cikinsu, Tnw = yanayi m ball zazzabi; Tg = zafin jiki na baƙar fata; Ta = bushe ball zafin jiki / iska zafin jiki
