Thermomelt® Surface Temperature Indicating Sticks
Precision surface temperature indicating sticks for fast, low-cost measurements with superior accuracy
THERMOMELT® HEAT-STIK® markers, manufactured by Markal, are a quick, low-cost method to accurately measure surface temperatures of various metals and equipment. The stick-in holder design provides convenience and durability for long-lasting use in the workshop or in the field. Please note that the color of the Thermomelts are not a part of their function, since the temperature signal consists of melting. Indicator color is subject to change without notice.
PROCESS: The precise temperature is reached once the stick has fully melted.
DURABILITY: The Long-Lasting Stick represents a much higher value proposition.
ACCURACY: Consistently accurate temperature readings with no calibration required. ( +/- 3% Celsius & +/- 1% Fahrenheit)
IDEAL FOR:
- Preheating
- Annealing
- Stress Relieving
- Post-Weld Heat Treating
- Interpass Temperature Monitoring
FEATURES:
- Shirt-Clip
- Adjustment Ring
- Protective Holder
Prevents breakage and improves handling
