Weiss Industrial Glass Thermometer | A9VU35-110FC | 3.5″ Stem | -40 to 110°F/C
Product Description
The A9VU35-110FC is part of the premium Weiss 9-inch scale industrial series. The “VU” (Vari-angle) designation represents a significant innovation in installation flexibility, allowing the thermometer head to be rotated 360° and tilted 180°. This allows maintenance teams in Dubai and Abu Dhabi to align the scale for perfect visibility, even when pipes are installed in tight or awkward overhead configurations.
This model is scaled for -40 to 110°F (-40 to 43°C). This wide, low-end range makes it uniquely suited for Chilled Water (CHW) supply lines, glycol cooling loops, and systems that may be exposed to sub-freezing temperatures. The 3.5-inch (90 mm) stem is the standard length for most commercial piping, providing a rapid thermal response by sitting directly in the fluid stream.
Key Features
- Fully Adjustable Vari-angle Head: Eliminates the need for fixed “straight” or “90-degree” models, allowing for perfect visibility in any installation scenario.
- Low-Temperature Resolution: The -40 to 110°F range is optimized for cooling systems, providing clear data for monitoring critical temperature differentials.
- Standard 3.5″ Industrial Stem: Designed for versatile fitment into standard pipe tees and mechanical systems.
- Eco-Friendly Sensitivity: Uses a high-visibility, non-toxic blue spirit liquid (mercury-free) that is environmentally safe and highly accurate.
- Rugged Valox® Housing: The case is made from impact-resistant GE Valox® polyester, designed to withstand the high humidity and mechanical vibration of UAE plant rooms.

Frequently Asked Questions
- Q: Why use the -40 to 110°F range instead of 0-120°F?
- A: This model is preferred for systems that use glycol or other anti-freeze agents where temperatures can drop below 32°F (0°C). It provides critical monitoring for low-temperature safety.
- Q: Does this require a thermowell?
- A: For pressurized piping, this thermometer must be installed in a 3.5″ Weiss Thermowell (typically model E35-35BS) to allow for instrument removal without draining the system.
- Q: Is the blue liquid easy to read in dark mechanical rooms?
- A: Yes, the high-contrast white scale and vivid blue liquid are designed specifically for high legibility in industrial environments.
