Your challenges on ventilation systems

Ventilation systems differ in three main points:

  • Type and velocity of flow
  • Location and method of measurement
  • Degree of contamination of the air

Unfortunately, you never know beforehand what type of conditions a system will have before you begin working on it. This is why it is important that your measurement technology not only have the right probes, but also be efficient and easy to operate. This is the only way to ensure accurate results and that systems are properly adjusted for optimal performance, even on busy days.
