Amplifiers

The EMMS strain gauge amplifier is compatible with the TPF 100, TPP 200, and TBP 300 series of pressure transducers.  Housed within an AIU series amplifier rack, our amplifiers provide a wide range of gain settings suitable for use with any of the EMMS range of plethysmographs.  A unique indicator on the front panel highlights out of range conditions.
