Biosystemsk² is a computer controlled top test bench used to evaluate the performance of self-contained breathing apparatus and other types of respiratory protective equipment. Its menu-driven software makes testing breathing apparatus a snap. SCBA performance may be checked without disassembly and without special tools. This product automatically tests all major functions of the user's SCBA in minutes, records the data, displays tabular and graphical test results on the computer monitor, and can print out the results of the tests on a built-in printer.

With menu-driven software, this test bench uses a breathing machine to simulate a worker's breathing pattern, and is capable of breathing rates up to the NFPA "High Performance" mandated 103 liters per minute. It tests for breathing resistance while simulating the full range of cylinder feed pressure Additional tests include mask leaks, high pressure leaks, alarm accuracy, bypass valve operation, and pressure gauge accuracy.
