Product description

The Dwyer BTB3605D is a high-accuracy bimetal thermometer designed for industrial and commercial temperature monitoring in boilers, chillers, and refrigeration equipment. It features a large 3-inch dial for easy reading and a 6-inch stainless steel stem for deep immersion into pipes or tanks. The dual-scale display provides readings from 0 to 250°F and -20 to 120°C, with a ±1% full-scale accuracy that ensures reliable data for system optimization. The hermetically sealed case prevents moisture from entering the dial and clouding the lens, while the robust stainless steel construction protects the internal bimetallic element from environmental damage. This thermometer is commonly used in HVAC systems to monitor water temperatures and ensure that heating and cooling cycles are operating within the specified parameters. Its reliable mechanical design requires no batteries or external power, providing a fail-safe monitoring solution for critical infrastructure.
