The WBGT-301 is a light and portable WBGT Meter, suitable for heat stress risk assessment for sports, events and more.
Packed with functions and features, it is a top-of-the-line WBGT analyzer. It has a simple, yet elegant design with a focus on easy operability, and in an industry-first, achieved conformity to the industry-leading standard “JIS B 7922” (Measurement of WBGT with a Digital Analyzer) as a “Class 1.5” instrument for measurement precision.
The device is dustproof and water-resistant for peace of mind, rated to the equivalent of IP65.
Functions such as data transfer and onboard memory are also available to meet the common needs of users.
The WBGT-301 model is endorsed by the Japan Sport Association, and in addition to sports, is suitable for almost every situation outside of use in industrial settings where Globe temperature measurement over 60°C is required (see WBGT-302 model).
