Weiss Industrial Glass Thermometer | A9VU12-30-180 | 12″ Stem | 30 to 180°F/C
Product Description
The A9VU12-30-180 is part of the premium Weiss 9-inch scale industrial series. The “VU” (Vari-angle) designation refers to its fully adjustable mounting system, allowing the thermometer head to be rotated 360° and tilted 180°. This flexibility is essential for technicians in Dubai and Abu Dhabi to ensure perfect scale visibility even when pipes are located in high-reaching or difficult-to-access overhead positions.
This model is scaled for 30 to 180°F (0 to 82°C), making it highly optimized for Domestic Hot Water (DHW) and general heating water systems. The standout feature is the 12-inch (300 mm) stem, specifically designed for extra-large diameter pipes or systems with extremely thick thermal insulation, ensuring the sensor reaches the true core temperature of the fluid flow for maximum accuracy.
Key Features
- Universal Vari-angle Flexibility: The head can be adjusted in seconds to any viewing angle in the field, eliminating the need for separate straight or angle-style inventory.
- Extra-Long 12″ Industrial Stem: Specifically engineered for deep immersion in large-diameter pipelines and bypasses thick insulation with ease.
- Precise Hot Water Range: The 30-180°F scale provides high-resolution monitoring for hot water systems where setpoint accuracy is critical.
- Mercury-Free Blue Liquid: Utilizes a non-toxic blue spirit liquid that is environmentally safe and provides high visibility against the white scale.
- Rugged 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: Why use a 12″ stem instead of a 6″ stem?
- A: A 12″ stem is necessary for very large pipes or when pipes have thick thermal insulation (3-4 inches). It ensures the thermometer bulb is submerged deep into the active flow rather than just measuring the temperature near the pipe wall.
- Q: Is this thermometer suitable for chilled water?
- A: While it will work, the range (starting at 30°F) is better suited for hot water. For chilled water, a 0-120°F or -40-110°F model is typically preferred to allow for sub-freezing monitoring.
- Q: Does this include the thermowell?
- A: For pressurized applications, it must be installed in a 12″ Weiss Thermowell (typically model E12-35BS) to prevent system leaks and allow for maintenance without shutdown.
