Tempil 24411 Temperature Indicator 400°F Liquid 2 fl oz

Temperature Indicator for 400°F Applications

Tempil 24411 is a liquid temperature indicator calibrated for 400 degrees Fahrenheit with a stated accuracy of plus or minus one percent Fahrenheit. It comes in a two fluid ounce bottle with a brush-in-cap applicator for direct marking on glass, metal, plastic or rubber surfaces. The product is intended for annealing and heat-treating processes where visual confirmation of a specific temperature is required.

Users needing a single-point 400°F marker

This indicator suits technicians and fabricators who need a quick visual check that a workpiece has reached 400°F during annealing or heat-treating. It is not suited for buyers who require multiple temperature ratings, continuous digital readouts, or indicators calibrated for other specific temperatures. The formulation is limited to the single 400°F trigger point and the listed compatible materials.

Simple brush-on application with safety notes

The brush-in-cap design allows direct application without extra tools; the liquid dries and changes appearance when the target temperature is reached. Users must handle the product according to California Proposition 65 warnings because it contains a chemical known to cause cancer and reproductive harm. Proper ventilation and protective equipment are recommended during use.
