The QTII Personal Heat Stress Monitor is available and recommended for workers less able to tolerate the impact of heat stress.
Yes, the instruments automatically calculates and displays two separate WBGT values for indoor and outdoor applications.
An indication of ‘stay time’ is provided in accordance with several international standards.
The sensor has a reservoir that requires distilled water for accurate readings.
The QT44 and 46 models incorporate a 'waterless wetbulb' sensor for calculation of wet bulb temperature. This sensor is ideal when an instrument is required to operate for a long time or is unattended.
An area heat stress monitor measures WBGT (wet bulb globe temperature) in accordance with BS EN 27243. This requires measurement of natural wet bulb, globe and air temperatures.
If the wet bulb reservoir dries out inaccurate readings will be provided. Always maintain a reasonable level of water in the reservoir.
Physiological response to heat stress varies from person to person. Those who may be physically unfit, not acclimatised to the environment or taking medication or drugs may be less tolerant.
