Weiss Industrial Glass Thermometer | A9VD12-0-160 | 12″ Stem | 0 to 160°F/C
Product Description
The A9VD12-0-160 is part of the premium Weiss 9-inch scale industrial series. The “D” designation identifies this as a Rigid Straight thermometer. Unlike the adjustable “Vari-angle” models, this fixed-position design provides maximum stability and vibration resistance, making it ideal for permanent installation on horizontal pipelines in Dubai and Abu Dhabi plant rooms where the viewing angle is already established.
This model is scaled for 0 to 160°F (-17 to 71°C), a highly versatile range that covers both Chilled Water (CHW) and domestic warm water systems. The standout feature is the 12-inch (300 mm) stem, specifically engineered for extra-large pipelines or systems with thick thermal insulation (3-4 inches), ensuring the sensing bulb reaches the core of the fluid flow for the most accurate thermal reading.
Key Features
- Sturdy Rigid Straight Design: Offers a stable, fixed mounting that excels in high-vibration environments like pump skids and central cooling plants.
- Extra-Long 12″ Industrial Stem: Designed to bypass heavy insulation and reach deep into large pipes, ensuring the sensor captures the true core temperature.
- Versatile 0-160°F Range: A “bridge” range that is suitable for both cooling and low-temp heating applications.
- 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 humidity and mechanical stress of Middle Eastern mechanical spaces.

Frequently Asked Questions
- Q: Why choose a 12″ stem instead of a 6″ or 9″ stem?
- A: The 12″ stem is necessary for very large pipes (typically 16″ diameter and above) or when the pipe is wrapped in 4 inches of insulation. It ensures the thermometer bulb is fully submerged in the active water flow.
- Q: Can this be used for steam?
- A: This range only goes up to 160°F, which is below the boiling point of water. For steam applications, you would require a range such as 30-300°F or 50-550°F.
- 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.
