Tempil 28047 Temperature Indicator Stick 600°F 3 fl oz

Product Identity

The Tempil 28047 Temperature Indicator Stick is a purpose-built thermal marker for welding and heat-treating workflows. It serves welders, fabricators and inspectors who must verify that base metal reaches 600 °F before, during or after a weld pass. The stick format and slip-resistant metal holder allow quick, one-handed marking on iron and steel surfaces in the shop or field.

Capacity and Headroom

Each stick holds 3 fl oz of temperature-sensitive compound calibrated to melt at 600 °F with an accuracy of ±1 % °F and ±3 % °C. It reliably confirms pre-heat, interpass and post-weld heat-treat temperatures for carbon and low-alloy steels. The formulation is not intended for lower-temperature processes or for non-ferrous alloys, so it will not indicate the correct point on aluminium, copper or stainless grades that fall outside the validated range.

Upgrade Context

This indicator replaces hand-held crayons, liquid tempilstiks or visual colour-chart methods that lack documented code compliance. The jump is worthwhile when a job specification calls out ANSI/ASME B 31.1, B 31.3, ASME Section I, III, VIII or AWS D 1.1, because the stick meets those standards directly. It is not suited for applications that require multiple temperature points on the same workpiece or for automated temperature logging systems.
