Dwyer Instruments tl5s2 Straight Thermometer 30-240F

Product Description

The DWYER INSTRUMENTS tl5s2 is a Thrift Line straight bimetallic thermometer designed for temperature measurement in HVAC, plumbing, and light industrial piping systems. It covers a range of 30 to 240 degrees F, making it well suited for monitoring supply and return water temperatures, hydronic loop temperatures, and similar fluid-system applications. The unit ships with a thermowell, which allows installation into a pressurized line without draining the system. Licensed HVAC technicians and plumbers are the primary installers of this instrument.

This thermometer is typically used in residential and light commercial hydronic heating systems, chilled water lines, domestic hot water systems, and boiler piping. The straight stem configuration positions the dial face perpendicular to the pipe, which is common in horizontal or vertical pipe runs where direct front-of-pipe readability is needed. The included thermowell simplifies future removal and replacement of the sensing element without interrupting system operation.

Key Features

• Temperature range of 30 to 240 degrees F covers common HVAC and plumbing fluid-system operating conditions
• Straight stem design provides direct in-line installation on horizontal or vertical pipe runs
• Includes thermowell for installation into pressurized systems without shutdown or draining
• Thrift Line construction offers a cost-effective solution for standard temperature monitoring points
• Dial face oriented for easy front-of-pipe readability after installation

Compatibility

Designed as an OEM-style replacement or new-installation thermometer for residential and light commercial hydronic, plumbing, and HVAC piping systems requiring a straight-stem dial thermometer with thermowell.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off flow and relieve system pressure before installing or removing the thermowell from any pressurized piping. Apply appropriate thread sealant to the thermowell fitting in accordance with local plumbing codes before threading into the pipe fitting. Do not overtighten the thermowell or force the thermometer stem, as this can damage the sensing element.
