Material Composition:
- Base paper: High-quality wood-free pulp paper
- Coating layer: Leuco dye-based thermal-sensitive coating (black mark on white background)
- Core: Cardboard or plastic tube, 50.8 mm ID
Structural Features:
- Perforated edge guides on both sides for precise alignment in recorder feed mechanism
- Start-mark printed on leading edge for automatic chart positioning
- Foil-wrapped packaging protects against humidity and light exposure
Functional Features:
- Produces permanent black mark on white paper when heated by the recorder’s thermal print head
- High contrast for clear visual reading of recorded trends
- Smooth feed mechanism compatibility — designed for consistent tension during recording
Applicable Industries:
- Oil & Gas — process trend recording in remote locations
- Chemical Plants — continuous process variable charting
- Power Plants — boiler and turbine parameter recording
- Water Treatment — flow and level trend documentation
Installation Requirements:
- Load paper roll with leading edge facing the correct direction (indicated by arrow on roll)
- Thread paper through the guide rails and under the thermal print head
- Set recording speed and chart division before starting recording
- Ensure recorder cover is closed to protect paper from ambient light and dust
Usage Precautions:
- Store in dry environment (relative humidity < 70%) — moisture degrades thermal coating
- Do not touch the thermal coating surface — skin oils cause smudging
- Use paper before expiration date — expired paper produces faint or no marks
- Replace paper roll only when recorder is in STOP mode to avoid print head damage
