ODEM-1 Oxygen Deficiency/Enrichment Monitor

The ODEM-1 Oxygen Deficiency/Enrichment Monitor from EMS Healthcare LLC is designed to continuously monitor oxygen levels in medical gas manifold rooms at healthcare facilities and provide alarm indicators at the room entrance when oxygen levels within the room fall below 19.5% or exceed 23.5%. Local alarm indicators include a red flashing beacon and an audible buzzer to warn facility personnel of deficient or enriched oxygen conditions before entering the room. These alarm indicators engage when the oxygen level exceed limits and will automatically silence once the level returns within limits.
