APT300 Inexpensive Pressure Transducer
The APT300 transducer is an inexpensive pressure
transducer which can be used to measure arterial blood pressures
in all species, even on mice with a high heart rate.
It can be used for measurement of arterial pressure in vivo as
well as for perfusion pressures in isolated perfused organs such
as heart or kidney. It can also be used to measure isovolumetric
left ventricular (using a balloon) pressures in isolated hearts
from mice up to rabbits or pigs.
The transducer consists of a contact plate with cable and the
exchangeable transducer head, which can easily be replaced. Contact
plates with cables for different amplifier types are available.
