For boiler systems, hot water heaters, or any industrial application where you need to monitor both pressure AND temperature at a single point, this Winters Instruments TTD405 Tridicator is the professional tool. It combines two gauges in one with a clear 3-inch dial, showing pressure (0-200 psi/kPa) on the outer scale and temperature (70-320°F) on the inner scale. The wetted parts (what touches the medium) are brass, and it features a sturdy steel case with a glass lens. Its ranges are compliant with ASME boiler codes, making it a reliable choice for hot water and steam systems. It has a bottom connection with a 2-inch brass stem for installation into a threaded socket. With an accuracy of +/- 3-2-3% and a 1-year warranty, it's a durable, industrial-grade instrument designed for long-term service. Essential for maintenance engineers, facility managers, or serious DIYers working on heating systems to ensure safe and efficient operation.
