TEMTS0350 - Tempil 350°F Temperature Indicator Crayon

Precision Temperature Indication for Industrial Processes

The Tempilstik 350°F (177°C) is the original temperature-indicating stick, designed to provide a simple, rugged, and reliable method for measuring surface temperatures in a wide range of industrial applications. For decades, professionals in manufacturing, metal fabrication, and maintenance have relied on Tempilstik to ensure critical temperature thresholds are met during heating processes. Unlike electronic sensors that require calibration, batteries, or complex setups, the Tempilstik utilizes the laws of physics—specifically the melting point of formulated compounds—to deliver accuracy you can trust.

When the stick is applied to a workpiece, it leaves a dry, opaque mark. Once the surface reaches the rated temperature of 350°F, the mark instantly melts into a distinct liquid smear. This phase change is sharp and unmistakable, allowing operators to verify temperature at a glance. With an accuracy of +/- 1% of the rated temperature, the Tempilstik 350°F is traceable to NIST standards, making it suitable for quality-critical operations where documentation and precision are paramount.

Reliability in Harsh Environments

Industrial environments are often too harsh for fragile digital thermometers. The Tempilstik is built to perform in the presence of static electricity, welding arcs, and rough handling. It effectively marks on various surface textures, including smooth metal, rough castings, and even rusty or oily materials. Whether used for annealing, stress relieving, or monitoring operating temperatures of bearings and motors, this tool provides a cost-effective solution for thermal management.

Key Benefits for MRO and Fabrication

• Zero Calibration: Eliminates downtime associated with calibrating electronic devices.
• Instant Results: Visual melt occurs immediately upon reaching 350°F.
• Versatile Application: Works on steel, iron, aluminum, and other substrates.
• Certified Accuracy: Meets the stringent requirements of industrial quality control systems.

Choose the Tempilstik 350°F for a foolproof, economical alternative to expensive pyrometers and thermocouples in your daily operations.
