Weiss Industrial Glass Thermometer | TL5A2 | 5″ Stem | 30 to 130°F/C
Product Description
The TL5A2 is part of Weiss’s specialized 5-inch scale industrial series, designed for durability in environments where space is a consideration but precision is non-negotiable. The “A” designation identifies this as a Rigid 90-Degree Angle thermometer. This configuration is specifically engineered for installation on vertical pipelines, allowing the scale to face the technician horizontally for easy reading in Dubai and Abu Dhabi plant rooms.
This model features a temperature range of 30 to 130°F (0 to 55°C), which is perfectly optimized for Chilled Water (CHW) and cooling tower applications. The narrow range allows for larger, more legible graduations around the critical 40°F-50°F marks. The 5-inch (125 mm) stem provides ample immersion depth to bypass standard pipe insulation and reach the heart of the fluid stream for accurate thermal sensing.
Key Features
- Rigid 90-Degree Angle: Offers a vibration-resistant, fixed mounting specifically designed for vertical pipe runs, ensuring the display is oriented correctly for operators.
- Chilled Water Optimized: The 30-130°F range provides the high resolution needed for precise cooling system monitoring.
- 5″ Industrial Stem: Specifically designed for versatile fitment into standard pipe tees, ensuring deep immersion in the fluid flow.
- Mercury-Free Blue Liquid: Features a high-visibility, non-toxic blue spirit liquid that is environmentally safe and easy to read against the white scale.
- Rugged Valox® Case: Housed in an impact-resistant GE Valox® polyester case that withstands the high humidity and mechanical vibration of Middle Eastern mechanical spaces.

Frequently Asked Questions
- Q: Why use the 30-130°F range instead of 0-120°F?
- A: The 30-130°F range is specifically tailored for water-based cooling. Because the range is slightly tighter, the marks are easier to read for fine-tuning chilled water efficiency.
- Q: Does this include the thermowell?
- A: For pressurized piping, it must be installed in a 5″ Weiss Thermowell (typically model E5-35BS) to prevent leaks and allow for maintenance without shutdown.
- Q: Can this be mounted on a horizontal pipe?
- A: For a horizontal pipe, the TL5S2 (Straight) model is usually preferred so the face stands upright. The TL5A2 is designed to stand out from a vertical pipe.
