The growing emphasis on worker safety has created a need for the environmental heat stress monitoring system
The growing emphasis on worker safety has created a need for the environmental heat stress monitoring system manufactured by IST.
Our RSS-214 system employs a unique, patented sensor to provide fast and highly accurate readings of the environmental parameters relating to human heat stress.
The system is used worldwide to monitor all types of work environments such as industrial, construction, and athletics.
Typical response time is less than three minutes. The thermal measurements (in Celsius or Fahrenheit) are calculated in hundredths of degrees and reported in tenths of a degree.
Here are some tips for better WBGT readings:
Use only a clean wick.
The wick should be easy to wet and it should wet uniformly. If it does not, it has been fouled by water hardness.
The wick should be white in color, not dirty.
Use distilled water only.
Avoid demineralized or deionized waters whenever possible.
Do not use tap water.
Shield dry bulb in high-radiant flux fields, such as summer sun, or foundries.
Place instrument in an area where workers will be: 4 feet above the floor and at least 1-1/2 feet from a worker or object.
The time-weighted-mean WBGT is a tedious calculation required only if the task to be performed by the worker requires the person to move through various differing heated areas. The time-weighted-mean can be measured directly using a personal WBGT datalogger.
When refilling the water reservoir during use, add water to the sponge, not to the wick. This will avoid erroneous wet bulb readings.
