Heat stress measuring device TC100

Climatic workplace assessments made easy: quick, precise and conforming to standards

The TC100 is a multifunctional diagnostic device for professional climate checks and quickly determines the WBGT index, e.g. for the assessment of thermally stressed workplaces.

By means of a special function direct sunlight can either be disregarded or taken into account for adjusted measurements in interior spaces or outdoor areas. You can also define an individual WBGT alarm threshold. There will be an immediate acoustic indication when this value is exceeded.

Moreover, the TC100 is able to determine virtually any measured variable relevant for climatic comfort.

Be it air temperature, humidity, radiant heat, wet-bulb and dew point temperature or air pressure – all these parameters can be called up in real time, indicated on the backlit display as held, minimum, maximum or average value and up to a capacity of 99 measured values saved directly on the TC100.

For long-term measurements the TC100 can also be attached to a tripod. In addition, the measuring device houses both a mini USB port and a barrel-type 9 V coaxial power socket. These ports permit a continuous mains operation as alternative to the battery-powered application. Also, to ensure a mobile power supply via the mini USB port, the TC100 may be connected to a powerbank.

No other stand-alone hand-held WBGT measuring device on the market can detect a greater number of different measured variables:

  • Climate index (WBGT) for indoor and outdoor areas
  • Radiant heat (black globe)
  • Heat index (HI)
  • Air temperature
  • Relative humidity
  • Dew point temperature
  • Wet-bulb temperature
  • Air pressure
The backlit LCD display of the TC100 simultaneously indicates four parameters that can also be read in poorly illuminated surroundings.

Standard-compliant measurement of the WBGT index

Persons working at installations or in environments with a high energy output or thermal radiation are greatly exposed to the risk of heat stress.

Amongst other measures exposure and rest periods adapted to the respective load level have been stipulated for the health protection of these employees.

The thermal load intensity is calculated from various climatic factors. The internationally standardized term for this climate index is WBGT index (wet-bulb globe temperature).

This index, originally developed by the US military for boot camps, is now defined in DIN EN 27243 and i.a. serves for the development of guidelines regarding work breaks and restrictions for thermally stressed workplaces.

Other than for the WBGT, the TC100 can also be used to determine the heat index – also referred to as humidex – which describes the combined effect of humidity, temperature and radiant heat on the human body.

Since the physical performance decreases at increasingly high temperatures, WBGT and heat index are more and more often used to aid the decision-making process of professional athletes or on sports events.
