Belmed Nitrous oxide Flowmeters are essential for measuring and controlling gases in critical applications for healthcare providers. The conscious sedation delivery systems come in either built-in or portable nitrous oxide units (using cylinders) and offer the highest levels of precision, patient comfort, and equipment safety. Most Nitrous Oxide Systems come with a flowmeter, stand and components to delivery gases safely to the patient. Both mobile and affixed flowmeter products meet the highest safety and quality standards for precise and efficient nitrous oxide delivery in the dental and medical professions. Available in three styles – cabinet-mounted, wall-mounted or free-standing – all flowmeters feature glass tubes for accurate visual flow readings and needle valves to provide easy adjustment of gas flow.
