Review LEWIS ENGINEERING Aviation Cylinder Head Temperature Indicator Gauge 0-300 Not Tested

The Lewis Engineering 28004-1 Cylinder Head Temperature Indicator Gauge is a precision instrument designed to provide accurate and reliable temperature readings for engine cooling systems. This analog gauge is suitable for a wide range of applications, including automotive, marine, and industrial engines.

The gauge features a 3-inch (76.2 mm) dial with a crisp white face and black markings for easy reading. The dial is graduated from 0 to 300 degrees Fahrenheit (0 to 149 degrees Celsius), allowing for comprehensive temperature monitoring. The dial also includes a red temperature warning zone between 180 and 220 degrees Fahrenheit (82 and 104 degrees Celsius), alerting operators to potentially dangerous engine temperatures.

The Lewis Engineering 28004-1 gauge is constructed from high-quality materials, including a brass housing and a heavy-duty glass lens. The brass housing is resistant to corrosion and provides excellent heat conductivity, ensuring the gauge can accurately measure temperature fluctuations. The heavy-duty glass lens is shock-resistant and scratch-resistant, making it ideal for use in demanding environments.

The gauge includes a threaded 1/8 NPT (National Pipe Thread) connection for easy installation on a variety of engine cooling systems. The connection is equipped with a rubber gasket to prevent leaks and ensure a secure fit. The gauge also includes a 6-inch (152.4 mm) length of 3/16 inch (4.8 mm) ID braided stainless steel hose for connecting the gauge to the engine cooling system.

The Lewis Engineering 28004-1 Cylinder Head Temperature Indicator Gauge is a valuable tool for engine monitoring and maintenance. Its precise temperature readings, durable construction, and easy installation make it an essential component for any engine cooling system. Whether you're a professional mechanic or a DIY enthusiast, this gauge is an indispensable addition to your toolkit.
