Can pyrometers be used to test psi in the exhaust pipe or turbocharger?

Pyrometers are designed to measure temperature, particularly in applications like monitoring exhaust temperatures in diesel engines. While they are essential tools for assessing the thermal efficiency and performance of components like exhaust pipes and turbochargers, they do not measure pressure, such as psi (pounds per square inch).

The measurement of psi in exhaust systems and turbochargers typically requires pressure gauges or sensors specifically calibrated for pressure measurements. These tools provide critical information about the system's performance, such as boost pressure in turbocharged engines or exhaust back pressure, which are crucial for diagnosing issues like restrictions or performance losses.

Thus, stating that pyrometers can be used to test psi would be inaccurate, confirming that the correct response is that it is false.
