Lutron WBGT-208 – Small Size Heat Index WBGT Meter

Circuit

Custom one-chip of microprocessor LSI circuit.

Display

LCD size : 52 mm x 38 mm
LCD with green backlight ( ON/OFF ).

Measurement

• *  Wet bulb globe temperature ( WBGT )

  @ Indoor/Outdoor

• *  Black globe temperature ( TG )
• *  Air temperature ( TA )

WBGT formula

* Wet bulb globe Temp.

Indoor/Outdoor and no sun : WBGT = ( 0.7 x WB ) + ( 0.3 x TG )

Outdoor and full sun :
WBGT = ( 0.7 x WB ) + ( 0.2 x TG ) + ( 0.1 x TA )

WBGT alarm setting
