Medical Gas Monitor 

The AG-920RA Multi-Gas Module provides you with quick and accurate measurement of anesthesia gases including CO2, N2O, O2, up to two anesthetic agents (automatically selected from Halothane, Isoflurane, Enflurane, Sevoflurane, Desflurane) and respiration rate. Quick access windows display 5 waveforms (O2, CO2, N2O and 2 agents) with easy-to-view numerical data color-coded to match each waveform; comprehensive graphic trends of all parameters; a tabular data list that gives you minute-by-minute values of all anesthetic agents, gases and vital signs; and a user-selectable alarm for all parameters. The AG-920RA has been discontinued.

Incorrect Statement?

The statement above "This product is not sold in the U.S by the manufacturer" is either not true or we were sold a restricted device. We have purchased from NK and still use the AG-920RA module for our Surgery site.

If it should not have been sold in the US then I would appreciate the info.
