SA Instruments, Inc. designs, manufactures and sells physiological monitoring and gating systems for use with small animals. SAII works closely with research scientists in major universities and bioresearch facilities worldwide to solve exacting problems associated with small animal research.

The Model 1025 monitoring and gating system was developed specifically for use with anesthetized mice and rats in the high field MR environment. The system operates with MR systems operating at field strengths in excess of 20 Tesla for heart rates up to 900 beats per minute. With recent advances in molecular genetics and the description of the mouse genome, the mouse model has become extremely important for understanding and characterizing human genes.
