AS ONE 4-1659-11 Black Sphere Type Portable Heat Stroke Meter　WB-123GT

Features

• This tester complies with JIS B 7922:2023 Class 2 electronic wet-bulb globe temperature (WBGT) index meter.
• We measure radiant heat (heat from solar radiation and reflection from the ground) with a black sphere, and accurately measure the environment by taking into account the black sphere temperature, temperature and humidity.
• Two heat stroke prevention guidelines are supported, and the heat stroke caution level for the selected guideline is displayed as a bar graph. (“Exercise Guidelines for Prevention of Heat Stroke ” and“ Guidelines for Prevention of Heat Stroke in Daily Life ”)
• Since this instrument can be switched between solar radiation and non-solar radiation measurement, accurate measurement can be performed according to the measurement environment.
• When the set heat stroke level is reached, a buzzer sound or LED flashes to let you know.
• *The buzzer sound can be set to ON/OFF. (LED flashing cannot be turned off.). If the specified heat stroke level continues to be exceeded, the alarm continues every 10 minutes for 2 seconds. If the heatstroke caution level rises or falls above the set heatstroke caution level, the alarm operation will be performed for 10 seconds to notify the change of the caution level. The sound of the buzzer changes according to the heat stroke warning level.
• The tester is a compact size that is convenient to carry.
• In addition, it is equipped with belt mounting parts, carabiner and neck strap as standard, and can be installed on a tripod (optional) with tripod mounting hole.
• A key lock function is provided to prevent measurement stop due to malfunction.
