M307CD Differential Intercooler O.A.T Gauge

The M307CD Differential Intercooler O.A.T. Gauge is an aircraft engine monitoring instrument designed to indicate the temperature differential across an intercooler system. By displaying temperature changes before and after the intercooler, it allows pilots and maintenance personnel to assess intercooler effectiveness and overall induction system performance.

This type of gauge is commonly installed in turbocharged aircraft where monitoring charge air temperature is important for managing engine efficiency and thermal margins. The differential presentation provides a clear visual indication of intercooler performance under varying power and environmental conditions.

Manufactured by UMA Instruments, the M307CD is designed for installation in certified aircraft when approved by applicable aircraft data. When properly installed and connected to the appropriate temperature probes, it delivers reliable temperature indication to support informed engine operation and monitoring.
