Photo shows medium pneumotach with optional R3850 heater control.
Pneumotach Amplifier has 2 analog outputs, one for flow and one for pressure. Dual Amplifier provides only analog flow output for each pneumotach. Consider Pneumotach Calibration which presets range control and provides chart of volts out vs. flow and pressure (volts vs. flow only on dual amp). For dual amp must buy 2 calibrations.
Heater Control must be purchased separately.
