Hans Rudolph Linear Pneumotachs
Specifically designed, patented and manufactured for Physiological
and Respiratory testing, the Hans Rudolph linear pneumotachs
utilise a unique housing configuration and screen assembly design
to convert the flow of gas in either direction into a proportional linear
signal of differential pressure from the two pressure taps for input into
a differential gas pressure transducer. Models are available with the
appropriate parameters, such as Volume Dead Space, Linear Flow
Range and Large/Small Flange Port tube size connection.
All models are available as Heated and Non-Heated Pneumotachs
and are supplied with an individual calibration record.

Hans Rudolph Pneumotach
Amplifier series 1110
Provides the instrumentation necessary to produce an analogue
output proportional to flow when connected to any Hans Rudolph
linear pneumotach. It will also provide an analogue output of an
independent auxiliary pressure signal for measurement of pressure
anywhere in the circuit.
Features
• Flow Ranges from 0-3, 0-5, 0-10, 0-35, 0-100, 0-160,
0-400 and 0-800 litres per minute
• Zero and gain adjustment pots for both outputs
• LED Flow direction indicator

1110A Pneumotach amplifier +/- 70cmH2O range
1110B Pneumotach amplifier +/- 140cmH2O range
Hans Rudolph Research
Pneumotach RSS100
The RSS100 and RSS100/HR research systems measure gas
flow using the differential pressure method. As gas flows through
the pneumotach, the microprocessor based system converts the
measured differential pressure to volumetric flow rate. Flow and
pressure measurements are used to calculate several ventilatory
parameters such as respiratory rate, lung compliance, tidal volume,
minute volume, positive end expiratory pressure, etc.
Features
• Custom Windows software for displaying, storing and
reviewing data
• Embedded microprocessor calculates flow rates and
provides correction for gas density, viscosity, temperature,
barometric pressure and airway pressure
• Flow Ranges from 0-3, 0-5, 0-10, 0-35, 0-100, 0-160, 0-400
and 0-800 litres per minute
The RSS100/HR is for use with linear pneumotachs. Please
order the appropriate Hans Rudolph heated or non-heated linear
pneumotach and heater control unit.
The RSS100 is for use with adult and neonatal fixed-orifice
pneumotachs.
One of each size is supplied with the module.
Additional quantities sold separately.
