King Jim Launches "Heat Index Meter Black Globe Type" to Visualize Heat Levels Reflecting Radiant Heat

King Jim Co., Ltd. (headquartered in Chiyoda-ku, Tokyo) will launch the "Heat Index Meter Black Globe Type" (NTSK-3) on June 12, 2026. This product is designed to clearly communicate heat risk levels through alarm sounds and a large display. The release is prompted by a record high of approximately 100,000 ambulance transports due to heatstroke in 2025, and the enforcement of revised industrial safety and health regulations in June 2025, which mandated heatstroke countermeasures in specific working environments. The "Heat Index Meter Black Globe Type" is equipped with a black globe that measures radiant heat from sources like sunlight and road reflections, adhering to JIS B 7922:2023 Class 2. It calculates the Wet Bulb Globe Temperature (WBGT), which reflects the human body's heat stress, making it suitable for assessing heat conditions in outdoor work sites. The device also features LED flashing in addition to alarm sounds to signal dangerous conditions, ensuring visibility even in noisy environments such as factories and construction sites. King Jim aims to expand its presence in the heat countermeasure product market with this new offering. Key features include compliance with JIS B 7922:2023 Class 2 for workplace heat management, accurate outdoor heat assessment via black globe temperature, humidity, and air temperature, an easy-to-read LCD displaying WBGT and four risk levels, adjustable alarm volume, and versatile installation options including a belt, carabiner, tripod screw hole, and wall hook hole, supporting both indoor and outdoor modes.
