REED 8778 Heat Stress Meter

REED Heat Stress Meter: instrument description

Along with having a Wet Bulb Global Temperature reading , the Reed 8778 Heat Stress Meter is a perfect instrument for those in need of measuring Heat Stress. Reed 8778 measures how hot it feels when humidity is combined with temperature, air movement and radiant heat and provides audible alarm when conditions enter the caution and danger zones. Reed 8778 comes also with Black Globe Temperature (TG) function to monitor the effects of direct solar radiation on an exposed surface. Its tripod mount design makes the Reed 8778 particularly useful in activities requiring long-term monitoring.
