------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------

Black Globe Heatstroke Index Meter with WBGT Alarm, JIS B 7922 2023 Compliant, KO392, Temperature Measurement, Heatstroke Prevention, Mandatory, Heatstroke Prevention, Heatstroke Meter, Temperature, Heatstroke Alarm ■ Mandatory heatstroke prevention measures and the social background Heatstroke prevention measures will become mandatory for companies starting June 1, 2025. This will apply to workplaces where workers work for a certain period of time in an environment with a temperature of 31°C or higher or a WBGT of 28 or higher. Heatstroke accidents are also increasing in schools and welfare facilities, making on-site measures an urgent priority. *WBGT (heat index) is an index that focuses on the heat exchange (heat balance) between the human body and the outside air, and incorporates three factors that have a large impact on the human body's heat balance: humidity, the surrounding thermal environment such as solar radiation and radiation, and temperature. [What is a black ball?] The "black ball" allows us to measure radiant heat from sunlight and the ground, quantifying the "heat that the body actually feels." This makes it possible to grasp the risk of heatstroke both indoors and outdoors, and is useful for safety management during exercise and work. *Radiant heat: direct sunlight and reflected heat from the ground. *The Ministry of the Environment also recommends the "heatstroke index meter with black ball." [How is it different from a thermometer?] While a typical thermometer can only measure "temperature," this product evaluates "temperature, humidity, and sunlight (radiant heat)" all at once and displays the heat danger level (WBGT value). For example, when exercising or doing outdoor activities, the strain on the body can change significantly depending on sunlight and humidity. The big difference with this product is that it makes the "true heat" visible and can determine the risk of heatstroke.
