The QUESTemp° III is the culmination of extensive research funded by the Electric Power Research Institute and performed by Westinghouse Electric and Pennsylvania State University. The research indicated that body temperature combined with heart rate were the best indicators of acute heat stress exposures.
The QUESTemp° III is a miniature datalogging instrument for monitoring individual body strain in response to heat stress. The wearer is provided with specific information on their physiological state, which helps them safely extend their exposure to acceptable limits of physiological strain.
Extremely compact, the QUESTemp° III is comprised of a sensor belt assembly and a monitor module. The sensor belt assembly is worn comfortably around the chest and consists of an elastic belt, disk temperature sensor, heart rate sensor and audible/visual indicator. For hygiene purposes, the elastic belt is detachable from the other assemblies. The microprocessor-based monitor module combines the monitoring and datalogging functions into a compact unit. The monitor is so lightweight, it can be slipped into a shirt pocket or clipped onto a belt. Also, the monitor’s watertight construction permits decontamination by water spray. The QUESTemp° III is programmable for the appropriate age group and clothing type of the individual being monitored.
The QUESTemp° III has a special two-stage alert, which incorporates both visual and audio alarms to notify the worker. The first stage or Warning Alert indicates that either the body temperature, heart rate, or both, are approaching a level at which there is a limited amount of time to work. The second stage or Action Alert indicates that the worker should stop work immediately and take necessary actions, such as leaving the area.
The QUESTemp° III measures heart rate, temperature and heat strain alert status. These values are recorded once every minute. Each line of recorded data is stamped with the date and time. This is very useful for correlating events and pinpointing problems.
