Weiss Industrial Glass Thermometer | TL5A2 | 5″ Stem | -40 to 110°F/C
Product Description
The TL5A2 is part of the compact Weiss 5-inch scale industrial series. The “A” in the model name identifies this as a 90-degree Rigid Angle thermometer. This design is specifically engineered for installation on vertical pipes, allowing the scale to face the operator horizontally for easy reading in Dubai and Abu Dhabi plant rooms.
This model is scaled for a wide range of -40 to 110°F (-40 to 43°C), making it uniquely suited for Chilled Water (CHW), glycol cooling loops, and systems that experience sub-zero temperatures. The 5-inch (125 mm) stem provides ample immersion depth to bypass standard insulation and capture the true temperature of the fluid flow, ensuring a fast and accurate thermal response.
Key Features
- Rigid 90-Degree Angle: Provides a stable, fixed mounting specifically designed for vertical pipe runs, ensuring the dial faces the technician directly.
- Low-Temperature Resolution: The -40°F starting point is perfect for monitoring refrigeration systems and cooling plants in the Middle East.
- 5″ Industrial Stem: Designed for versatile fitment into standard pipe tees, ensuring the sensor reaches the core of the fluid stream.
- Mercury-Free Blue Liquid: Utilizes a high-visibility, non-toxic blue spirit liquid that is environmentally safe and easy to read.
- Durable Valox® Case: Housed in an impact-resistant GE Valox® polyester case that withstands high humidity and mechanical vibration.

Frequently Asked Questions
- Q: When should I use the TL5A2 instead of the TL5S2?
- A: Use the TL5A2 (Angle) for vertical pipes so the thermometer face stands out horizontally toward you. Use the TL5S2 (Straight) for horizontal pipes so the thermometer stands upright.
- Q: Does this require a thermowell?
- A: For pressurized piping, it must be installed in a 5″ Weiss Thermowell (typically model E5-35BS) to ensure a leak-proof seal and allow for maintenance without system shutdown.
- Q: Is the blue liquid easy to see in low-light plant rooms?
- A: Yes, the high-contrast white scale and vivid blue liquid are designed specifically for high legibility in industrial environments.
