Weiss Industrial Glass Thermometer | A9VU9/120FC | 9″ Stem | 0-120°F/C
Product Description
The A9VU9/120FC is a heavy-duty industrial thermometer engineered for precision and durability. It features a large 9-inch (225 mm) scale housed in a rugged, GE Valox® polyester case. The “VU” (Vari-angle) designation means the head can be rotated 360 degrees and tilted 180 degrees, allowing technicians in Dubai and Abu Dhabi to position the dial for perfect visibility regardless of pipe orientation.
This model is specifically scaled for 0-120°F (-17 to 49°C), making it the ideal instrument for Chilled Water (CHW) applications. The extra-long 9-inch stem is designed to penetrate deep into large-diameter pipes or through thick layers of insulation, ensuring the sensor reaches the heart of the fluid flow for the most accurate thermal reading.
Key Features
- Vari-angle Flexibility: The fully adjustable mounting allows for easy reading from any angle, eliminating the need for specialized “straight” or “90-degree” models.
- 9″ Extra-Long Stem: Specifically designed for large pipes and heavily insulated systems commonly found in UAE district cooling plants.
- Chilled Water Optimized: The 0-120°F range provides high resolution for monitoring cooling systems, where precise temperature differentials are critical for efficiency.
- Blue Liquid Sensitivity: Uses a high-visibility, non-toxic blue spirit liquid that is easier to read than traditional mercury and environmentally safe.
- Rugged Construction: The Valox® case is impact-resistant and highly durable in the high-humidity environments of Middle Eastern mechanical rooms.

Frequently Asked Questions
- Q: Why do I need a 9″ stem instead of a 3.5″ or 6″ stem?
- A: In large UAE infrastructure projects, pipes are often 12 inches or larger in diameter and wrapped in 2-3 inches of insulation. The 9″ stem ensures the thermometer reaches the fluid without being buried in the insulation.
- Q: Does this include the thermowell?
- A: This is the thermometer only. For a 9″ stem thermometer, you must pair it with a matching 9″ Weiss Thermowell (typically model E9-35BS) for a safe and leak-proof installation.
- Q: Can this be used for hot water?
- A: The maximum temperature for this model is 120°F. For hot water systems, the 30-240°F or 30-300°F models should be used.
