Model 221R Oxygen Deficiency Monitor

DESIGNED FOR SAFETY

The AMI MODEL 221R has become the gold standard for oxygen deficiency & confined space monitoring throughout the US market. It is used by the thousands in US Government Laboratories, Space Agencies, Universities, and a broad range of industries, ensuring the safety of personnel. The MODEL 221R is designed for use in NON-FLAMMABLE applications and provides an incredibly accurate and stable reading over a broad temperature range (0-130°F). The Analyzer is virtually maintenance-free with its unique oxygen sensor delivering a 10-year life expectancy.
