Compliant with JIS B 7922:2023! Comprehensive evaluation of temperature, humidity, and radiant heat.
The KO392 is a black globe heat stress index meter that displays the danger level of heat (WBGT value). While a typical thermometer can only measure "air temperature," this product evaluates "air temperature, humidity, and sunlight (radiant heat)" together. The presence of the "black globe" allows it to measure radiant heat from sunlight and ground reflection, quantifying the "actual heat felt by the body." It enables the assessment of heat stress risk both outdoors and indoors, aiding in safety management during exercise or work. It offers flexible installation options to adapt to various environments. It alerts users to heat stress danger levels through alarms and displays. **Features** - Displays WBGT, temperature, humidity, and time - Equipped with warning display and alarm function for heat stress risk - Three levels of alarm volume (loud/soft/off) - Includes a carabiner and two bands (one long and one short) - Flexible installation options for various environments *For more details, please download the PDF or feel free to contact us.*
