Detailed Overview

This is a dedicated 12-point analog temperature recorder used to monitor and document thermal processes, typically in heat treatment applications. It receives signals from up to 12 thermocouples and charts the temperature profiles over time onto a paper chart. The solution provides a permanent, physical record of the heating and cooling cycles, which is essential for quality control and compliance documentation in welding and stress relief.

Reliable, ink-based tracking of up to 12 temperature inputs for process control documentation.

• This recorder provides a permanent, verifiable paper record of temperature changes over time, using a circular chart and ink pens to track inputs from multiple thermocouples or sensors.
• It is primarily used for quality assurance and documentation in heat treatment and industrial ovens/furnaces where a physical signature record is required for compliance.
• The core product is the 12-point analog recorder unit, a supply of charts and ink pens, and an operations manual.
• The multi-pen (or dot matrix) system allows for clear differentiation between the 12 temperature channels.

Top Features & Benefits

• 12-point analogue paper chart temperature recorder.
• Records data from up to 12 separate inputs simultaneously for comprehensive coverage.
• Reliable paper-based record keeping that is instantly verifiable and non-erasable.
• High-temperature measurement capability (up to 1200 degree C).
• Robust enclosure designed for site and workshop use.

Primary Uses & Functions

Used for recording pre and post weld heat treatment (PWHT) processes up to 1200 degree C, recording temperature data at 12 distinct points for quality control and code compliance.

Real-World Applications

• Recording of Heat Treatment Cycles for piping, vessels, and other welded fabrications.
• Monitoring and documentation of stress relieving or post-weld heat treatment (PWHT) processes.
• Continuous temperature recording in industrial ovens, furnaces, and kilns.

Industry Solutions

• Oil & Gas (Welding and Heat Treatment compliance)
• Petrochemical (Furnace temperature logging)
• Power Generation (Boiler and pipe fabrication QA)
• Manufacturing (Aerospace, heavy fabrication)
