Introduction

Black bulb temperature (TG) Natural wet bulb temperature (TN)
Ambient (dry bulb) temperature (TA)
Relative humidity (RH) (not involved in WBGT calculation, display and screen reference values)
Based on the above measurements, Xtester-JT2020-2 can calculate:
WBGT (in) index, i.e. wet bulb black bulb temperature index (in case of no solar radiation)
WBGT (out) index, i.e. black bulb wet bulb temperature index (when there is solar radiation)

WBGT, also known as the temperature index of wet bulb and black bulb, is a basic parameter to evaluate the heat load of human contact working environment. WBGT shows an index that is related to the metabolism of specific jobs that produce heat intensity.
WBGT index is composed of three parts: natural wet ball TNW, black ball TG and dry ball ta (sometimes).
The calculation formula is as follows:
Without solar radiation indoors and outdoors: WBGT = 0.7tnw + 0.3tg
In case of outdoor solar radiation: WBGT=0.7Tnw+0.2Tg+0.1Ta
Where TNW = natural wet bulb temperature TG = black bulb temperature
TA = dry bulb temperature / air temperature
