The WLG-421 is a rugged, marine-grade metal-armored glass thermometer designed specifically for reliable temperature measurement in marine systems, industrial pipelines, boilers, and process equipment. It ingeniously combines a precision internal-scale glass thermometer with a heavy-duty metal protective casing, providing clear and intuitive readings while effectively shielding the sensing element from pressure, vibration, and corrosive media. Featuring a straight configuration and a robust V-shaped aluminum housing, this product maintains stable performance across a wide temperature range and has received extensive certification for both marine and industrial applications.
