Compact Flowmeters has a polycarbonate housing that extends over the lightweight aluminum body providing superior durability. Its state of-the-art housing incorporates a white backdrop that allows accurate adjustments and reading of the flow setting. The contemporary design results in a smaller flowmeter that fits more easily into space-cramped wall rails. The flow control knobs are on the front of the flowmeter in clear sight of the clinician and marked by gas type for added safety. Available in both air and oxygen models.
