Weiss Industrial Glass Thermometer | 45VA3-0-100 | 3″ Stem | 0-100°F/C
Product Description
The 45VA3-0-100 belongs to the Weiss 4500 series, offering high-level industrial accuracy in a compact 4.5-inch scale footprint. The “VA” designation identifies this as a 90-degree Rigid Angle thermometer, specifically designed for vertical pipe installations. This allows the scale to face the technician horizontally, ensuring clear visibility in Dubai and Abu Dhabi plant rooms where space is at a premium.
This model features a temperature range of 0 to 100°F (-17 to 38°C), making it highly optimized for Chilled Water (CHW) and cooling tower return systems. The compact 3-inch (75 mm) stem is ideally suited for smaller pipe diameters or narrow manifolds, providing accurate thermal readings without causing significant flow restriction.
Key Features
- Compact 4.5″ Scale: Perfect for installation on booster pumps, chiller skids, and in tight mechanical enclosures where a full-sized 9-inch model is too large.
- Rigid 90-Degree Angle: Provides a stable, vibration-resistant mounting for vertical pipelines, ensuring the face is oriented correctly for easy reading.
- Chilled Water Resolution: The 0-100°F scale provides detailed graduations, making it easy to monitor cooling system efficiency.
- Mercury-Free Blue Liquid: Features a high-visibility blue spirit liquid that is environmentally safe, non-toxic, and easy to read against the white scale.
- Durable Aluminum Case: Housed in a rugged, die-cast aluminum case that offers superior impact resistance compared to standard plastic models.

Frequently Asked Questions
- Q: When should I use the 4500 series (4.5″) instead of the 9″ series?
- A: Choose the 4.5″ scale when installing on compact equipment or in areas where a 9″ thermometer would be prone to accidental breakage due to its size.
- Q: Does this include the thermowell?
- A: For pressurized applications, this must be installed in a 3″ Weiss Thermowell (typically model E35-35BS or similar) to allow for safe maintenance and sensor protection.
- Q: Is this model suitable for outdoor use?
- A: Yes, the aluminum case and sealed glass front are designed to withstand the humidity and mechanical stress found in both indoor and outdoor UAE plant environments.
