Product details
Weiss Industrial Thermometer | A7VU35 | 0-120°F & °C | 7″ Scale
Product Description
The A7VU35 offers a streamlined 7-inch (175 mm) scale designed for installations with restricted head space. With a temperature range of 0-120°F (-17 to 49°C), it is specifically tuned for the UAE’s district cooling and building management sectors, providing precise monitoring for chilled water supply and return lines.
The “35” in the model code indicates it is optimized for a 3-1/2″ stem length, ideal for smaller diameter piping or compact equipment skids found in Dubai and Abu Dhabi’s commercial mechanical rooms. Despite its smaller profile, it utilizes a rugged GE Valox® polyester case, ensuring durability against high-ambient temperatures and humidity.
Key Features
- Compact 7″ Scale: Designed for readability in tight spaces where a standard 9″ scale might be too large.
- Vari-angle Adjustability: The head can be tilted and rotated to any angle, eliminating the need for fixed-angle (straight or 90°) thermometers.
- 3-1/2″ Stem Compatibility: Precision-matched for 3-1/2″ stems and thermowells, ensuring the sensing bulb is correctly positioned in the flow stream.
- Dual Scale Display: Simultaneously provides readings in Fahrenheit and Celsius to meet international engineering standards.
- Non-Toxic Blue Spirit: Features a high-visibility blue liquid filling that is safe, mercury-free, and provides $\pm$1% accuracy.

Frequently Asked Questions
- Q: Is the A7 series less accurate than the A9 series?
- A: No. Both the A7 (7″) and A9 (9″) series share the same accuracy rating of $\pm$1% of the full scale. The difference is only in the size of the housing.
- Q: Can I use this in a 6-inch thermowell?
- A: No. The “35” designation is specifically for 3-1/2″ stems. For a 6-inch well, you would require the A7VU6 model.
- Q: What is the benefit of the GE Valox® case?
- A: It is a high-performance polyester that does not rust, resists high impact, and handles the intense heat of UAE mechanical rooms better than metal or cheaper plastic.
