Weiss Industrial Glass Thermometer | A9VU9-30-240 | 9″ Stem | 30 to 240°F/C
Product Description
The A9VU9-30-240 is part of the premium Weiss 9-inch scale industrial series. The “VU” (Vari-angle) designation allows for total installation flexibility, enabling the thermometer head to be rotated 360° and tilted 180°. This ensures that operators in Dubai and Abu Dhabi can position the scale for perfect legibility, regardless of the pipe’s height or orientation.
This model is scaled for 30 to 240°F (0 to 115°C), making it ideal for Heating Water (HW), domestic hot water supply, and return headers. The standout feature is the 9-inch (225 mm) stem, which is specifically engineered to bypass thick layers of thermal insulation (common in high-efficiency UAE buildings) and reach deep into the fluid stream for the most accurate thermal reading.
Key Features
- Universal Vari-angle Mounting: Easily adjusts to any viewing angle in the field, eliminating the need for separate straight or angle-style inventory.
- Extra-Long 9″ Industrial Stem: Designed for large-diameter pipes or systems with heavy insulation, ensuring the sensor reaches the core of the fluid flow.
- Optimized Hot Water Range: The 30-240°F scale is specifically tailored for standard heating and hot water applications in commercial towers.
- Safety First (Mercury-Free): Utilizes a high-visibility, non-toxic blue spirit liquid that is environmentally safe and easy to read against the white scale.
- Durable Valox® Case: Housed in an impact-resistant GE Valox® polyester case, built to withstand the high heat and humidity of Middle Eastern mechanical rooms.

Frequently Asked Questions
- Q: When should I choose a 9″ stem over a 6″ stem?
- A: Use the 9″ stem if your pipe diameter is large (10″ and above) or if the pipe has more than 2 inches of thermal insulation. This ensures the thermometer bulb is fully immersed in the water flow.
- Q: Does this include the thermowell?
- A: For pressurized applications, this must be installed in a 9″ Weiss Thermowell (typically model E9-35BS) to ensure a leak-proof seal and allow for maintenance without system shutdown.
- Q: Is the case resistant to corrosion?
- A: Yes, the Valox® case is highly resistant to chemicals, moisture, and the saline air prevalent in coastal areas like Dubai.
