Thermal Comfort Datalogger with Transducers

Poor thermal comfort causes discomfort, headaches and even fatigue. As a result, people suffer both in terms of productivity and overall well being.

The 1221 makes it easier to collect and analyze thermal comfort results. It can be connected to a PC and works with the dedicated Application Software 7301. The 1221 either automatically stores the measurement results for later transfer to a computer or online measurements where the results are directly displayed on the computer screen.

Complies with ISO 7730/CEN 27730; ISO 7726 Class C; ISO 7243/CEN27243; ASHRAE 55; SAE J2234, ISO 14505.

Calculated Comfort and Heat Stress Indices:

• Predicted Mean Vote (PMV)
  
• Percentage of dissatisfaction (PPD)
  
• Draught rating 
  
• Turbulence intensity 
  
• Optimal operative temperature 
  
• Equivalent temperature 
  
• Effective temperature 
  
• Required sweat rate
  
• Wet bulb globe temperature

Uses:

• Measuring of all physical parameters necessary to evaluate heat stress and thermal comfort
  
• Calculating comfort indices PMV, PPD and DR
  
• Calculating heat stress indices WBGT and required sweat rate 
  
• Calculation of ET*
  
• For displaying measurement data and calculated indices as graphs in exportable format
  
• Long duration (weeks) monitoring of the time history of thermal parameters
   
• Logging data from third party transducers with analog outputs 
  
• As front end for a central data logger system
