Weiss Industrial Glass Thermometer | 45VA3-0-150 | 3″ Stem | 0-150°F/C
Product Description
The 45VA3-0-150 is part of the Weiss 4500 series, which offers the same industrial durability as larger models but in a more compact 4.5-inch scale size. The “VA” designation identifies this as a 90-degree Rigid Angle thermometer. This design is specifically engineered for installation on vertical pipelines, allowing the scale to face the technician horizontally for easy monitoring in Dubai and Abu Dhabi plant rooms.
This model features a temperature range of 0 to 150°F (-17 to 65°C), making it exceptionally well-suited for Domestic Hot Water (DHW) and general heating applications. The compact 3-inch (75 mm) stem is designed for smaller-to-medium pipe diameters or equipment manifolds, ensuring accurate temperature sensing without obstructing the fluid flow.
Key Features
- Compact 4.5″ Scale: Ideal for installation on equipment skids, pump sets, and in tight mechanical spaces where a full-sized 9-inch thermometer won’t fit.
- Rigid 90-Degree Angle: Provides a stable, fixed mounting specifically designed for vertical pipe runs, ensuring the face is oriented correctly for the operator.
- Optimized Hot Water Range: The 0-150°F scale provides high resolution for standard domestic water supply monitoring.
- Mercury-Free Blue Liquid: Utilizes a high-visibility, non-toxic blue spirit liquid that is environmentally safe and easy to read.
- Durable Aluminum Case: Housed in a rugged, die-cast aluminum case that offers superior impact resistance and durability in industrial environments.

Frequently Asked Questions
- Q: Why use a 4.5″ scale instead of a 9″ scale?
- A: The 4.5″ scale (4500 series) is used when space is limited, such as on small booster pump sets or OEM equipment where a larger thermometer would be obtrusive.
- Q: Does this include the thermowell?
- A: For pressurized systems, this thermometer must be installed in a 3″ Weiss Thermowell (typically model E35-35BS or similar) to allow for safe maintenance without system shutdown.
- Q: Is the aluminum case better than plastic?
- A: Aluminum cases provide better mechanical protection against impact and are often required by certain project specifications in the UAE for fire safety and durability.
