  • Temperature: 20°C to 35°C (68°F to 95°F)
  • Humidity: 35% to 80% RH 
• Pressurization / Timing: Reaching time for continuous pressure is approximately 5 seconds, with a maintenance time of 2 minutes. 

Common Applications

• Measuring tire pressure and contact patches 
• Inspecting pressure distribution of cleaning polishes against liquid crystal (LCD) panels 
• Checking contact and gasketing pressure between cylinder heads and cylinder blocks 
• Evaluating delicate assembly interfaces, lamination, and micro-mechanical contact points 

How to Use

1. Cut: Trim the A and C film sheets to match the dimensions of the target measurement area. 
2. Combine: Place the active/textured sides of the two sheets in direct contact to form a sandwich. 
3. Apply Pressure: Insert the sandwich into the interface and apply the operational force. 
4. Inspect: Red color patches will appear where contact pressure occurs; evaluate the color density visually or digitize/quantify it using tools like the
