Temperature measuring instrument Omnia57

for the aerospace industrywith screenautomatic

Overview
Omnia CHT-EGT measures exhaust gas temperature (EGT) for each cylinder (up to 4) and cylinder head temperature (CHT) for up to 4 heads. It integrates up to eight independent gauges that can be enabled individually to match your engine configuration. The instrument is fully configurable to suit the majority of piston engines used in light aircraft. All Omnia family instruments feature a high-visibility 2.4" color display, a powerful 32-bit microcontroller and modern solid-state components to ensure long-term reliability and accuracy. Up to 16 Omnia instruments can be connected in a cluster for data exchange between units.
