Research Grade Blood Pressure Transducers

Research Grade Blood Pressure Transducers

Ideal for monitoring blood pressure during surgery. Sensitive enough for research applications.

This blood pressure transducer uses a semi-disposable dome of medical grade Silastic® with an integral silicone rubber diaphragm. Blood only contacts the diaphragm. Domes are supplied sterile and can be re-sterilized and reused without affecting calibration. Replacement domes are available separately.

Note: Shown with 73-1440 Lab Stand and 73-0566 Block Clamp

The Research Grade Blood Pressure Transducer uses a semi-disposable dome of medical grade Silastic® with an integral silicone rubber diaphragm. Blood only contacts the diaphragm. Domes are supplied sterile and can be re-sterilized and reused without affecting calibration. Replacement domes are available separately.

This transducer converts picofarad changes of capacitance into high-level DC voltages using a new electronic circuit (U.S. Patent #4,142,144). This circuit is extremely sensitive and stable, producing a signal suitable for direct connection to recorders, oscillographs and computers.

The transducer amplifier has a 3–digit back lit LCD display that reads directly in mmHg up to 999. Amplifiers can be stacked for multiple use. It is possible on special order to have as many as 4 amplifiers operated by one transformer.

This research grade blood pressure transducer is for use with:
• PowerLab Data Acquisition System
• HA-HSE Data Acquisition Hardware (73–3330, 73–0161)
• Harvard Apparatus TR2 Chart Recorder
• Modular Universal Oscillograph

Please note that replacement domes listed are for Harvard Apparatus' newer model transducer ONLY. The newer model is distinguished by a black threaded ring at the base of the dome. The older models have a white ring at the base of the dome. We are no longer able to offer replacement domes for these older units.
