Smart Probes application

Air conditioning/
refrigeration systems and heat pumps

  • Leak test
  • Superheating and subcooling
  • Target superheating
  • Cooling and heating output
  • Vacuum measurement

Ventilation systems

  • Volume flow in ducts and at outlets
  • Temperature/humidity measurement in ducts

Conventional heating systems

  • Non-contact temperature measurement
  • Measurement of flow and return temperatures
  • Measurement of gas flow pressure

Indoor air quality

  • Measurement of room temperature
  • Measurement of relative humidity

Smart Probes measure these parameters

Surface temperature using infrared, clamp thermometer on lines, air temperature
Hose-free high-pressure measurement and differential pressure
Relative humidity conjunction with temperature
Air flow velocity measurement and determination of volume flow in ducts or at outlets
