About this item

  • Accurate, fast, low-cost method for measuring surface temperatures
  • Ideal for applications such as annealing, forging, welding, bending, forming
  • Initially the mark appears dull and chalky then quickly melts to a transparent-appearing liquid
  • Accurate to within +/- 1 percent of rated temperature
  • 33 Percent bigger and stronger; same proven reliability


Thermomelt when temperature measurement is critical. The Markal Thermomelt temperature indicator with superior break-resistance is the industry’s largest, longest-lasting stick, improving efficiency and uptime. New Certified Thermomelt Heat Stiks are specifically analyzed and certified to contain low concentrations of halogens, sulfur and low melting point metals (less than 250 ppm). Ideal for use in nuclear power generation facilities such as shipbuilding, atomic energy or anywhere that nuclear certification is required. 33 Percent bigger and stronger; same proven reliability. Bigger, break-resistant stick cuts down on replacement costs. Improved holder features a durable metal shaft and convenient pocket clip. Gravity advance holder protects stick and prevents it from slipping back inside. Meets ANSI/ASME Code B32.1 and B31.3, AWS D1.1 and ASME Code Sec. I, III and VII, NIST traceable. Typical application includes: ship building, pressure vessels, boiler systems, bridge construction, power piping systems. Made in the USA.

This product works great just as intended. I find it useful when welding thin metal so I don't blow through although I have quite a few co-workers who find them useless in their specialties. I'd recommend buying this if you work with thin metal or need a somewhat accurate indicator of temperature when preheating metal. I give it 5 stars but this is a product that's usefulness is individualized. Always think before you buy but 20 dollars isn't terrible in this line of work either.

This item comes broken everytime. Useless garbage. I ordered a replacement and received this. Great quality control and a complete rip off.

I'm trying determine the temp of some brass that I am annealing. In theroy I get no melt at all below the specified temp. The brass pieces are smallish, so I get very little melt, but any melt tells me it's there. So over all I think it is indicating as needed. Overall it is the best method I have found yet. I will continue to use.

Works as described. I use this as a temp indicator on 30-30 brass. I now can anneal my brass when needed and know it is done at the right temp. It is less expensive that other products so it fits my budget better.Thanks Amazon and thanks Markal.

I'm sure this is a fine product and I'm looking forward to using it, but it was shipped loose in a thin plastic bag with no protective padding. The temperature stick inside the metal holder was broken into 3 parts. For my occasional use as a hobbyist, it'll be fine - no need to replace, but pro industrial welders, needing to check metal temperature frequently would want undamaged sticks.

I used this to test the skin temperature of rifle brass for annealing it. It fit the bill perfectly.

Total garbage. Dried out already when I got it. Won't stick to anything and just burns to black carbon instantly with any heat. Waste of money, get the better stuff.
