Ashcroft 50EI 42E 090 50-300F 5 BiMetal Thermometer

The Ashcroft EI Series 50EI 42E090 50–300°F 5-inch bi-metal thermometer is a rugged process-temperature instrument built for industrial use, featuring a 5" Maxivision dial for easy reading from a distance and reduced parallax. It employs an external-adjust bi-metal sensing element (the 50EI designation) and a 9" stem, providing reliable temperature measurement with a Fahrenheit scale across a 50 to 300°F range. The 42E configuration identifies a 1/2" NPT union connection with EveryAngle, allowing the dial to be rotated to the desired orientation for optimal installation on pipes, vessels, or equipment. Designed for general industrial applications, this thermometer supports robust monitoring in heating or cooling lines, tanks, and other process environments where durable, straightforward temperature indication is required.
