Pneumotach

This Pneumotach Amplifier provides the instrumentation necessary to produce an analog output proportional to flow when connected to any of our standard Pneumotachs. It will also provide an analog output of an independent auxiliary pressure signal for measurement of pressure anywhere in the circuit.

• For use with Linear Bidirectional Pneumotachs
• Two pressure ranges available:
  • 70 to 70 cmH₂O or
  • 140 to 140 cmH₂O
• Zero and gain adjust ports for both outputs
• BNC type analog output jacks
• Flow direction indicator LED

The Pneumotach Amplifier works with any of our Linear Bidirectional Pneumotachs that are available in seven different calibrated flow ranges in heated and non-heated versions. Please specify country when ordering.

The accessories work with the Harvard Apparatus Pneumotach Amplifier for produce an analog output for flow and pressure.

The HSE pneumotachometer PTM is a transducer for airflow measurement on rodents. The main feature of the new design is the small dead space. This ensures a good gas exchange in acute experiments. In combination with the silicon rubber tubing and the tracheal cannula the PTM is used for acute experiments (Intubation or tracheotomy). It is also designed for respiratory flow measurement on isolated lung of rats, guinea pigs or mice.

• Ideal pneumotachs for mice, rats or guinea pigs
• For isolated lung applications
• Small dead space volume
• Transparent design permits early detection of mucus in the pneumotach which helps to eliminate erroneous measurements 

These Linear Pneumotachometers have a special screen design which assures a linear signal over a range of flow rates and have minimum dead space.

• For use with Differential Pressure Transducers
• Available heated or non-heated
