INTRODUCTION
The Sper Scientic WBGT SD Card
Datalogger (Model 800037) is an intelligent
meter that reads wet bulb globe temperature,
wet bulb temperature, dew point temperature,
humidity and air temperature, and black globe
temperature.
You can use the meter almost anywhere to
determine appropriate exposure levels and
meet OSHA or other safety standards for high
temperatures to avoid heat exhaustion and
heat-related injuries during athletic events,
military exercises, and industrial activities.
This meter features a real time SD memory
card datalogger. Standard,portable SD
memory cards provide unlimited data storage
and upload pre-formatted data directly to
Excel, eliminating the need for cables or
software. Alternatively, manually record 99
readings for on-screen review or stream data
directly to a computer using the optional
software and cables. Each data set includes
the temperature measurement (wet bulb
globe temperature, wet bulb temperature,
dew point temperature, humidity and air
temperature or black globe temperature) and
the time and date.
