2. Cylinder Head Temperature gauge - Wikipedia

   en.wikipedia.org/.../Cylinder_Head_Temperature_gauge

   Analog Cylinder Head Temperature gauge. A Cylinder Head Temperature gauge (CHT) measures the cylinder head temperature of an engine. Commonly used on air-cooled engines, the head temperature gauge displays the work that the engine is performing more quickly than an oil or water temperature gauge. As the engine works at high

3. Leak-down tester - Wikipedia

   en.wikipedia.org/wiki/Leak-down_tester

   The input pressure is set for 80 psi (550 kPa), and 60 psi (410 kPa) minimum cylinder pressure is the accepted standard. While the leak-down tester pressurizes the cylinder, the mechanic can listen to various parts to determine where any leak may originate.

4. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   This type of test is suitable for containers such as boat fuel tanks, which are not pressure vessels but must work under the hydrostatic pressure of the contents. A hydrostatic test head is usually specified as a height above the tank top. The tank is pressurised by filling water to the specified height through a temporary standpipe if necessary.

5. Exhaust gas temperature gauge - Wikipedia

   en.wikipedia.org/wiki/Exhaust_gas_temperature_gauge

   An exhaust gas temperature gauge (EGT gauge or EGT sensor) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR).

6. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   The h is also known as the pressure head. When expressed as a pressure head, pressure is specified in units of length and the measurement fluid must be specified. When accuracy is critical, the temperature of the measurement fluid must likewise be specified, because liquid density is a function of temperature.

7. Air flow bench - Wikipedia

   en.wikipedia.org/wiki/Air_flow_bench

   H, pressure drop across test piece in pascals measured by the test pressure manometer d , density of air in kilograms per cubic meter ( 1.20 kilograms per cubic meter at standard conditions ) This represents the highest speed of the air in the flow path of a normally shaped port, at or near the section of minimum area ( through the valve seat ...
