The TRIPLETT Model HSDL300 Heat Stress WBGT (Wet Bulb Globe Temperature) Meter monitors indoor/outdoor heat stress to help limit the danger of heat-related injury. It simultaneously displays Air or Globe Temperature， Humidity， and Wet Bulb Globe Temperature (WBGT). Memory stores up to 12，000 readings each containing Air Temperature， Humidity， WBGT， and Globe Temperature with a user programmable sampling rate of 1-minutes， 5-minutes， 10-minutes， 30-minutes， 60-minutes， 90-minutes， 120-minutes. A USB interface is used for transferring stored readings to your PC in csv format. It features a programmable audible and visual WBGT alarm and a backlight that changes color as the WGBT value increases (Green/ Yellow/Red/Flashing Red). An In/Out function switch measures WBGT with or without the effects of direct sunlight. °F/°C switchable. Tripod mount can be used to free-up your hands when taking measurements over an extended amount of time. Includes (4) AAA batteries and a mini USB cable. 1-year warranty. For outdoor athletic training and events， construction， iron and steel foundries， brick firing plants， glass facilities， boiler rooms， mining sites， and other areas where heat stress levels should be monitored.
