This study developed an instrument for monitoring and recording environmental stress. Basically, the instrument (ENVIREC) is a portable, battery powered, data acquisition system designed for unattended operation for eight hours. The unit measures the environmental parameters of dry bulb temperature, wet bulb temperature, globe temperature, and air velocity using plug-in sensors mounted on the top of the instrument. The sensor outputs are scanned, conditioned, scaled, converted to digital form, and recorded on magnetic cassette tape at fifteen minute intervals. The data being recorded can be displayed on the front panel digital display. Recorded information can be played back and observed on the digital display or converted to an IBM compatible tape using the tape reformatter unit.
