Resideo TG250-UT Thermometer
The Resideo TG250-UT is a professional-grade bimetal dial thermometer engineered for high-accuracy temperature monitoring in hydronic heating systems and mechanical rooms. Featuring a robust 2.5-inch face, this industrial temperature gauge provides clear visibility for technicians verifying system supply water or troubleshooting boiler performance. It is built with a rugged stainless steel well and a 1/2-inch NPT threaded connection, ensuring long-term durability and corrosion resistance in demanding HVACR environments.
Designed for streamlined serviceability, the Resideo TG250-UT thermometer includes a removable well that allows for sensor replacement or calibration checks without the need to drain the entire loop. This makes it an essential component for boiler piping temperature monitoring, radiant floor systems, and domestic hot water applications. By integrating this HVAC dial thermometer into your installs, you ensure consistent thermal tracking and easier preventive maintenance for commercial and residential hydronic assets.
Key Benefits:- High-Visibility Display: Large 2.5" dial allows for quick, accurate readings from a distance.
- Rugged Construction: Durable stainless steel well protects the sensing element from high-pressure and corrosive fluid environments.
- Efficient Serviceability: Threaded well design permits thermometer removal without system depressurization or fluid loss.
- Versatile Compatibility: Standard 1/2" NPT connection fits most common hydronic and HVAC systems.
- Precision Performance: Reliable bimetal coil technology provides stable temperature tracking for critical HVACR logistics.
Where is the best location to install the Resideo TG250-UT?
For the most accurate hydronic temperature monitoring, install the thermometer in the supply or return piping near the boiler or manifold, ensuring the stem is fully immersed in the flow to avoid false readings from stagnant areas.
Does this unit require a separate thermowell?
No, the Resideo TG250-UT comes complete with a 1/2-inch threaded well, facilitating a secure and leak-proof installation immediately out of the box.
Can I use this for domestic hot water systems?
Yes, its stainless steel well and 2.5-inch dial make it ideal for monitoring temperatures in public facilities, nursing homes, and industrial hot water loops.
