Pressure Measurement in Physiology and Biology

 

 

Biological Pressure Meter PRM-4x

 

Research grade pressure meter (monitor) for physiology and biology. It is optimized for biological measurements carried out with PC-based data acquisition (DAQ) systems. PRM-4x Pressure Meter has extremely high input sensitivity, excellent linearity and very fast recording speed.

 

The input pressure range is wide enough to cover nearly every biological research application. Any pressure appearing in the body of an experimental animal can be measured with it, such as blood pressure, intra-cranial pressure (ICP), breathing in the mouth, pressure in the lung, or any other pressure signal.

Combitrans Pressure Sensor

 

PRM-4x Pressure Meter has been designed to use the standard, popular, surprisingly reliable, however cheap Combitrans pressure detector (sensor) units. The Combitrans detectors are standardized products. They are cheap, because they are used in the human practice as disposable parts, but in spite of this, they have got excellent linearity, very high recording speed and surprisingly good long-term stability. Supertech Instruments provides non sterile Combitrans sensors assembled with the appropriate plug for PRM-4x.
