Weiss Industrial Glass Thermometer | TL5S2 | 5″ Stem | -20 to 120°F/C
Product Description
The TL5S2 is part of Weiss’s compact 5-inch scale series, designed for applications where space is limited but industrial durability is required. The “TL” designation identifies this as a Rigid Straight thermometer. Unlike the adjustable “Vari-angle” models, this fixed-position design provides maximum stability in high-vibration environments such as pump skids and mechanical plant rooms in Dubai and Abu Dhabi.
This model features a temperature range of -20 to 120°F (-30 to 50°C). This range is specifically optimized for Chilled Water (CHW) and cooling systems, providing high resolution around the critical 40°F mark. The 5-inch (125 mm) stem ensures the sensing bulb penetrates deep into the pipeline, reaching past the insulation to capture the true temperature of the flowing medium.
Key Features
- Rigid Straight Mounting: Offers a heavy-duty, fixed installation that is highly resistant to mechanical shock and piping vibration.
- Chilled Water Optimized: The -20 to 120°F range provides excellent resolution for cooling systems and refrigeration headers.
- 5″ Industrial Stem: Specifically designed for versatile fitment in mid-sized pipes, ensuring accurate immersion in the fluid stream.
- Mercury-Free Blue Liquid: Utilizes a non-toxic blue spirit liquid that is environmentally safe and highly visible against the white scale.
- GE Valox® Case: Housed in a durable, impact-resistant polyester case that withstands the high humidity and mechanical stress of UAE mechanical rooms.

Frequently Asked Questions
- Q: Why use a rigid straight thermometer instead of a Vari-angle?
- A: Rigid thermometers are generally more cost-effective and are preferred for standard horizontal or vertical pipes where the view is already clear, or where vibration is high.
- 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 system leaks and allow for maintenance without shutdown.
- Q: Is it suitable for outdoor installation?
- A: Yes, the Valox® case and sealed glass front are highly resistant to UV rays and the saline coastal air found in areas like Sharjah or Dubai.
