Tempil 24411 Liquid Temperature Indicator 400 Degrees F

Product Description

The TEMPIL 24411 is a liquid temperature indicator designed to verify that a specific surface temperature has been reached during heat-related processes. Applied directly to a surface, the liquid dries into a dull, opaque film. When the surface reaches 400 degrees F, the film liquefies. As the surface cools, the mark re-solidifies into a visibly distinct residue, confirming the target temperature was achieved. Accuracy is plus or minus 1 percent F and plus or minus 3 percent C. The 2 fl oz bottle includes a brush-in-cap for direct application. Technicians and process engineers in industrial, HVAC, and fabrication trades use this product where thermal verification is required without instrumentation.

The TEMPIL 24411 is suited for a wide range of thermal verification tasks including annealing polished metal surfaces, heat-treating, wave soldering of PC boards, calibrating industrial ovens, calibrating brake calipers, dielectric heat sealing, and post-forming plastic laminate. It works on glass, metal, plastic, and rubber surfaces, making it applicable across multiple trade disciplines. The single-temperature rating of 400 degrees F makes it a precise go or no-go indicator for processes where hitting a specific thermal threshold is critical.

Key Features

• Rated indicator temperature of 400 degrees F with plus or minus 1 percent F accuracy
• Liquid form dries to opaque film, liquefies at target temperature, re-solidifies for visual confirmation
• Compatible with glass, metal, plastic, and rubber surfaces
• Includes brush-in-cap for controlled, direct surface application
• 2 fl oz bottle size suitable for field and shop use
• Applicable to thermal mapping, oven calibration, soldering, annealing, and heat-treating processes

Compatibility

Compatible with glass, metal, plastic, and rubber surfaces. Suitable for use in annealing, heat-treating, wave soldering, dielectric heat sealing, post-forming plastic laminate, brake caliper calibration, and industrial oven calibration applications.

Installation Notes

Apply the liquid to the target surface using the included brush-in-cap before heat is introduced. Allow the applied film to dry fully before beginning the heating process. Ensure the work area is properly ventilated when using near open flame or high-heat equipment. Follow applicable workplace safety guidelines for handling liquid chemical indicators.
