Black globe type portable heat stroke meter WB-123GT 1 piece

This device is an electronic wet bulb globe temperature (WBGT) index meter that complies with JIS B 7922:2023 Class 2. Radiant heat (heat from sunlight and reflected light from the ground) is measured using a black globe, and accurate environmental measurements are made by taking into account the "black globe temperature," "temperature," and "humidity." It supports two heatstroke prevention guidelines, and the heatstroke warning level of the selected guideline is displayed as a bar graph. ("Heatstroke Prevention Exercise Guidelines" and "Heatstroke Prevention Guidelines in Daily Life") This device can be switched between measuring with and without solar radiation, allowing accurate measurements to be made according to the measurement environment. When the set heatstroke level is reached, a buzzer will sound and an LED will flash to alert you. ★※The buzzer sound can be set to ON/OFF. (The LED flashing cannot be turned OFF). If the condition continues to exceed the set heatstroke level, the alarm will sound for 2 seconds every 10 minutes. If the heatstroke warning level rises or falls above the set heatstroke warning level, the alarm will sound for 10 seconds to notify you of the change in warning level. The tone of the buzzer will change depending on the heatstroke warning level. This device is compact and easy to carry. It also comes standard with a belt attachment part, carabiner, and neck strap, and has a tripod mounting hole so it can be mounted on a tripod (optional). A key lock function is provided to prevent measurement interruptions due to malfunction.
