Feature
■ Conforms to JIS B 7922 Class 2
SK-150GT complies with the Class 2 (accuracy of WBGT index: ±2°C) of JIS B 7922 "Electronic wet bulb globe temperature (WBGT) index meter" which is used as a guide for preventing heat stroke and estimating heat stress in working environment, promulgated in March 2017, in the following measuring range:
Temperature: 20.0 to 40.0°C; humidity: 30.0 to 90.0%rh
■ Alarm function
A buzzer sounds when the WBGT reaches a set level.
■ Display hold function and display of minimum and maximum available.
■ Switching measuring ambient mode between outdoors and indoors available. Auto power-off when not in use for 20 minutes equipped.
■ A hard case is attached for easy carrying and storage.
■ A tripod below sold separately is recommended for continuous measurement. Select a location free from heat radiation.

Makes the globe of the unit 150 cm high from the ground.
Description
■ What is a heat stress monitor?
SK-150GT is a compact all-in-one heat stress monitor that can measure temperature, humidity and heat radiation to calculate WBGT index, which is used as a guide for preventing heat stroke and estimating heat stress in a hot environment.
Check sensory temperature with your eyes to prevent heat stress. Useful at following situations:
- physical education and club activities at school
- any indoor and outdoor sports activities
- working in high temperature
- construction, agriculture, and other manual labors
■ WBGT index
The WBGT, stands for wet bulb globe temperature, is an index to estimate heat stress stated in ISO 7243, which is a sensory temperature calculated from wet bulb temperature, globe temperature (heat radiation), and dry bulb temperature.
It is necessary to select appropriate mode of the measuring ambient before the calculation since it varies depending on its measuring ambient.
The index is derived from the following formulas.
WBGT (Indoors, or outdoors without sunlight) = 0.7 WB + 0.3 TG
WBGT (Outdoors) = 0.7 WB + 0.2 TG + 0.1 DB
(Where WB = wet bulb temperature, TG = globe temperature, DB = dry bulb temperature)
■ Heat stress
Heat stress, or heat stroke, is a generic term of heat-related illness that the body temperature regulation is damaged, and water and saline get lost owing to hot and humid environment.
It may cause even casualty, however, the risk can be reduced by observing the ambient and by being aware of overheating and dehydration.
