Peak Pressure Indicator MSI-4

Peak Pressure Indicator MSI-4



The Leutert Peak Pressure Indicator MSI-4 measures the maximum firing pressure of internal combustion engines. It is attached to the engine via an indicator valve. The slim line dimensions of this peak pressure indicator were chosen to allow easy installation in the narrow spaces of smaller size four-stroke engines. Nevertheless the MSI-4 engine indicator, sometimes called Peak Pressure Gauge, may be used on vessels with two stoke and four stroke Diesel or gas engines, generators, and air compressors.

It is hallmarked by simple operation and a high degree of instrumental precision in all speed ranges. Its sturdy design makes it immune to vibrations requiring extremely low maintenance.

The peak pressure indicator is attached to the engine via an indicator valve.
