Tempil BQ041-11 Tempilstik Temperature Indicator

Description:

The TEMPIL BQ041-11 TEMPILSTIK Temperature Indicator is used in industrial heat processing applications to verify that a surface has reached a specific temperature of 1050°F (566°C). Commonly applied during welding, heat treating, annealing, brazing, and furnace maintenance where accurate surface temperature verification is required without electronic measuring instruments. Maintenance technicians, welders, and quality control personnel use this temperature indicating stick to confirm process temperatures, validate heat treatment procedures, and ensure compliance with manufacturing specifications.

Applications:

The TEMPIL BQ041-11 TEMPILSTIK Temperature Indicator is widely used in welding, metal fabrication, shipbuilding, railroad maintenance, oil and gas production, power generation, and industrial manufacturing. The temperature-sensitive stick instantly melts when the rated surface temperature of 1050°F (566°C) is reached, providing a fast, accurate, and irreversible visual indication without calibration or electrical power. It is ideal for verifying preheat, inter-pass temperatures, post-weld heat treatment, stress relieving, and other high-temperature industrial processes.
