Tempilstik Temperature Indicators

Tempilstik temperature indicators provide a simple and reliable way to verify metal temperatures during welding, fabrication and heat treatment. Available in a wide range of temperature ratings, each Tempilstik melts at its specified temperature, providing a clear visual indication that the required temperature has been reached. Easy to use, portable and requiring no batteries or electronics, Tempilstiks are ideal for checking preheat and interpass temperatures and helping maintain consistent welding quality.

Key benefits of Tempilstik temperature indicators

• Accurate temperature indication – each Tempilstik is manufactured for a specific temperature, allowing you to check whether the metal has reached the required temperature.
• Simple visual indication – the temperature is reached when the Tempilstik mark melts, giving a clear indication without needing to interpret a digital reading.
• Ideal for preheating before welding – helps welders confirm that material has reached the specified preheat temperature before welding begins.
• Helps prevent overheating – useful for monitoring maximum temperatures and reducing the risk of damaging heat-sensitive materials.
• No batteries or electronics – they're simple mechanical temperature indicators, so there's no calibration, battery or electronic equipment required.
• Fast and convenient – apply a small mark to the workpiece and observe it during heating.
• Wide temperature range – Tempilstik products are available in a large selection of temperature ratings, making them suitable for different welding and heat-treatment requirements.
• Works in demanding environments – particularly useful in workshops and fabrication environments where conventional temperature measurement can be inconvenient.
• Portable and easy to use – a Tempilstik can be kept in a toolbox and used wherever temperature verification is required.
• Cost-effective – provides a straightforward alternative or supplement to electronic temperature measurement equipment.
• Calibration - free with 100% reliability
• Accurate to within +/- 1% of Fahrenheit and +/- 3% Celsius rated
