Hans Rudolph 3850 Pneumotachometer Heater Control 3850A – Precision Heating for Respiratory Flow Measurement

Hans Rudolph 3850 Pneumotachometer Heater Control 3850A – Precision Heating for Respiratory Flow Measurement

• The Hans Rudolph 3850A Pneumotachometer Heater Control Unit is a reliable and specialized device designed to work with Hans Rudolph linear pneumotachs, delivering consistent heating to maintain precise flow measurement accuracy. Whether you’re in a clinical or research setting, maintaining temperature stability in pneumotach systems is essential to ensure accurate and repeatable airflow readings.

• This unit functions as the central control module for heating Hans Rudolph pneumotachs—ideal for reducing condensation in the flow head and maintaining optimal calibration across varying ambient conditions. It pairs seamlessly with the Hans Rudolph Pneumotach Amplifier PA1, enabling a clean analog output proportional to either pressure or flow.

The 3850A Heater Control Unit is sold as-is (unit only—no cables or accessories), in used condition with normal signs of wear. It is well-suited for labs or institutions looking for a cost-effective replacement or spare unit for their existing Hans Rudolph airflow measurement setup.

Key Features:

• Compatible with Hans Rudolph linear pneumotachs

• Works with the PA1 Amplifier for analog output of flow and pressure

• Supports configurations for dual flow or pressure channels

• Maintains thermal stability for accurate respiratory measurements

• Used condition with normal signs of wear – unit only

Whether you’re involved in respiratory research, lung function testing, or ventilator development, this unit provides the consistency and compatibility needed for demanding measurement applications.
