    Founded in 1978, Blue Ribbon Corporation had its origins as a direct distributor of gauges and thermometers to satisfy a growing need among industry OEMs. These OEMs required higher volumes of lower cost instrumentation that could offer necessary value for investment, yet which would never compromise on quality. Since that time, Blue Ribbon has evolved into its own brand of products, with its main manufacturing facility also producing Pressure Transmitters & Level Sensors. Blue Ribbon has also routinely partnered with OEMs and industrial instrumentation manufacturers to custom design gauges, thermometers and accessories to exact industry specifications.
