Designed for commercial dive operators and hyperbaric facilities, the Multigas SAT Color connects to and displays data on up to six (6) sensors, such as oxygen (O2), carbon dioxide (CO2), hydrogen sulfide (H2S), humidity, temperature, and pressure, among others. The color display allows for continuous monitoring of gases and other factors in a variety of environments, including hyperbaric chambers and diving bells up to 35 bar (508 psi | 1150 fsw). Its nonvolatile memory retains settings for up to 10 years without power. The Multigas SAT Color comes in a single water-resistant carrying case and is custom-built to user specifications.
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:

WARNING: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator may be required. A faulty Flow Restrictor can lead to a false analyzer reading. Flow Restrictors should be regularly tested with a Flow Meter. Inaccurate gas analysis can lead to serious personal injury or death.
