The Nuvair Multigas Color is mounted in a water- and impact-resistant case with a powder-coated aluminum instrument panel. TFT 320×240 dpi color display with backlit LED generates 600 nits (cd/m²) light intensity and allows for viewing of dynamic gas concentration graphs. For hyperbaric chamber operations, both the Multigas SAT instrumentation box and sensors can be placed inside of the chamber to allow for onboard monitoring, or the sensor connections can be routed outside of the chamber to allow for external monitoring. The unit can display the following values:
- - Actual reading of sensors
- - Partial Pressure (PP) of gas sensors
- - Surface Equivalent Value (SEV) of the sensors related to surface pressure of 14.7 psi (1 bar)
- - Sensor electrical values
- - Graph of sensor values over time
