FLUS MT-HS01 WBGT Heat Stress Meter with Black Globe and Hygrometer

FLUS MT-HS01 WBGT Heat Stress Meter with Black Globe and Hygrometer

The FLUS MT-HS01 is a heat stress meter that combines three sensors in one compact housing: a digital air temperature sensor (0 to 50 °C), a black globe temperature sensor (0 to 80 °C) and a digital relative humidity sensor (20 to 90 %RH). From these readings it calculates the WBGT (wet-bulb globe temperature) heat stroke index over 0 to 50 °C with 0.1 °C resolution.

Two WBGT modes are available: IN (indoor) mode for measurements indoors or outdoors on cloudy days, and OUT (outdoor) mode for measurements outdoors in direct sun. WBGT is widely used in workplaces and sports to control physical activity in hot environments and limit the danger of heat-related injuries.

The reading is updated once every 20 seconds, and the instrument runs on two 1.5 V AAA batteries for about 6 months.
