This Brannan bimetal indoor dial thermometer is an accurate and affordable solution for monitoring temperatures in dry, indoor, or commercial environments. Ideal for HVAC, hot water systems, and light industrial use, it offers Brannan's signature quality. A potential caveat is its suitability primarily for dry environments, not for direct immersion in liquids without a pocket. Key features include a 100mm steel case, chrome bezel, quality bimetal movement, and a 1/2" BSP brass pocket for installation.

This thermometer is ideal for general dry indoor or commercial applications, including monitoring temperatures in HVAC systems, hot water systems, and light industrial environments.
No, this thermometer is designed for dry applications. It should be used with the provided brass pocket for installation into systems where it can measure the temperature of the surrounding medium (like air or pipe wall) without direct liquid contact.
A bimetal thermometer uses two different metals bonded together. As temperature changes, the metals expand or contract at different rates, causing the strip to bend. This bending action is used to move the thermometer's pointer on the dial.
Clean the exterior with a soft, slightly damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the case or lens.
The brass pocket allows for easy installation and removal of the thermometer without needing to drain or shut down the system it is installed in. It also protects the thermometer stem.
No, this model is intended for dry, indoor, or controlled commercial environments and is not weatherproof.
Warranty information is typically provided by the retailer. Please refer to your purchase documentation for details.
Ensure the thermometer stem is fully inserted into the brass pocket and that the pocket is securely installed. Verify the ambient temperature is within the thermometer's range. If the issue persists, consider if the thermometer requires recalibration.
This indicates moisture ingress. The thermometer may not be suitable for the environment or may have been exposed to condensation. Remove the thermometer and allow it to dry completely in a warm, dry place. If fogging persists, replacement might be necessary.
Ensure you are using a compatible fitting (1/2" BSP). Clean the threads on both the pocket and the fitting before attempting installation. Do not overtighten.
