Marshall Instruments Gauges: Precision Meets Performance
When it comes to monitoring what's happening under the hood — or inside an industrial system — few names carry the breadth and depth of Marshall Instruments. Spanning performance automotive gauges all the way to heavy-duty pressure measurement tools, Marshall Instruments has built a reputation for accuracy, durability, and smart design. Their gauges represent one of the most versatile lineups available, blending modern electronics with purposeful engineering.
The Comp II LED Series: High-Tech Performance Monitoring
At the heart of Marshall Instruments' automotive performance offering is the Comp II LED Series — a line of 2-1/16" gauges engineered for drivers who demand more from their instrument cluster. These stepper motor-driven gauges feature one-touch peak recall and user-programmable high/low full-dial warning functions, available for a wide range of applications including boost, vacuum, oil pressure, oil temperature, water temperature, and voltmeter. That combination of smart alerts and peak memory makes them especially useful for performance tuners tracking engine behavior under load.
SCX Technology and Style Variants
Marshall Instruments also produces the Comp II SCX line, available in Black, Silver, and White dial finishes — giving builders flexibility to match their interior aesthetic without compromising function. The 2-1/16" gauges in this family feature SCX Pro technology with one-touch peak recall and user-programmable high and low warnings. For those restoring or building classic American muscle cars, the 60s Muscle Series is a standout choice: Marshall Instruments brings period-correct styling together with modern technology , complete with chrome bezels, 270° full-sweep stepper motor movements, and two-color through-dial lighting.
Liquid-Filled and Direct-Mount Mechanical Gauges
Not every application calls for electronics. Marshall Instruments' liquid-filled and non-filled direct-mount mechanical gauges offer straightforward, reliable pressure readings in a variety of dial sizes and configurations. Options include mechanical liquid-filled pressure gauges in both black and white dial finishes across multiple PSI ranges. These gauges are well-suited for shop environments, engine bays, or anywhere a robust, easy-to-read mechanical gauge is preferred over a digital solution.
Factory Match and MINI Series
For OEM-minded enthusiasts who want gauges that look factory-installed, Marshall offers the Factory Match and MINI series. Marshall Instruments has developed a unique line of performance gauges specifically for an OEM look. These compact options are ideal for tight dash configurations where space is at a premium but accuracy cannot be compromised.
Built to Last
All Marshall Instruments gauges include a one-year warranty, reflecting the brand's commitment to quality construction and customer confidence. Whether you're dialing in boost pressure on a turbocharged build, keeping tabs on transmission temperature on a long-haul tow rig, or simply upgrading a tired OEM cluster, Marshall Instruments gauges deliver the readability and reliability that serious drivers rely on.
