HWBM-Series

HWBM Series hot water bimetal dial thermometers provide direct temperature indication for hydronic heating systems and other hot water applications. The series includes 2.5 inch and 4 inch dial sizes with rear connections and configuration-specific mounting options.

The thermometers use zinc-plated brass cases, chrome-plated brass rings, glass windows, white aluminum dials with black and red markings, black-finished aluminum pointers, and brass stems. An external reset supports field recalibration.  Accuracy is ±5°F (2°C) accuracy and an ambient temperature range of -40 to 250°F (-40 to 120°C).

Standard models provide a 30 to 250°F and 0 to 120°C scale. The 2.5 inch and 4 inch dial options support different reading requirements, while thermowell and spring-mount configurations accommodate different installation methods. A magnet-mount option is also available - contact factory.
