DC bridge amplifier designed for invasive blood pressure measurement
Amplifier for invasive blood pressure measurement
The unit has been designed to measure specifically arterial, venous or cardiac ventricular pressure. Accordingly, it has internal calibration options, and can be connected to any blood pressure sensor in the market (default SEN-02). It is a guaranteed low -noise design with high filtration level.
