Weiss Industrial Glass Thermometer | TL5S2 | 5″ Stem | -40 to 110°F/C
Product Description
The TL5S2 is part of the robust Weiss 5-inch scale industrial series. Unlike the “Vari-angle” models, the “TL” designation identifies this as a Rigid Straight thermometer, offering a fixed, sturdy mounting ideal for vertical or horizontal pipelines where the viewing angle is already established.
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 refrigeration systems that experience sub-zero temperatures. The 5-inch (125 mm) stem provides deep immersion to bypass pipe insulation and capture the true temperature of the fluid flow, ensuring a fast and accurate thermal response.
Key Features
- Rigid Straight Design: Offers a stable, vibration-resistant mounting for long-term industrial use in mechanical plant rooms.
- Low-Temperature Precision: The -40°F starting point is perfect for monitoring glycol systems and cooling plants in Dubai and Abu Dhabi.
- 5″ Industrial Stem: Designed for versatile fitment into standard pipe tees, ensuring the sensor reaches the core of the fluid stream.
- Eco-Friendly Sensitivity: Utilizes a high-visibility, non-toxic blue spirit liquid (mercury-free) that is environmentally safe and easy to read.
- Compact 5″ Scale: Provides a space-saving footprint while maintaining high contrast and clarity for quick temperature checks.

Frequently Asked Questions
- Q: Why use the -40 to 110°F range instead of 0-120°F?
- A: This model is essential for systems that may drop below freezing (32°F / 0°C). It provides critical monitoring for low-temperature safety in specialized cooling processes.
- Q: Does this require a thermowell?
- A: For pressurized piping, this thermometer 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 case resistant to corrosion?
- A: Yes, the Valox® case is highly resistant to chemicals, moisture, and the saline air prevalent in UAE coastal industrial zones.
