Why are Avongard Tell-Tales the best?
Key Reasons:
- Precision and Readability: Unlike crude visual assessments, they use an overlapping transparent plate with fine crosshairs over a millimetre-calibrated grid. This allows you to easily track horizontal, vertical, and displacement movements with an accuracy of ±1.0 mm, or ±0.5 mm by visual interpolation.
- Superior Manufacturing: Standard printing methods (like silkscreening) can fade and lack definition. Avongard gauges are printed using a silicone pad and etched metal plate method, ensuring high definition, repeatability, and readability even in low-light conditions.
- Upgradable Resolution: By opting for the Avongard Plus Tell-Tale (TP11), users can upgrade the monitor’s resolution from 1.0mm to 0.1mm using digital or vernier calipers on the built-in datum spigots.
- Extreme Durability: Manufactured in Great Britain from tough, vandal-resistant polycarbonate, they can be reliably used in both internal and external environments.
- Structural Versatility: Aside from flat wall variants, specialised gauges such as the Avongard Corner Tell-Tale (TC21) and Avongard Displacement Tell-Tale (TD11) ensure accurate monitoring of uneven, 3D concrete surfaces and inside/outside wall angles.
Every genuine Avongard instrument comes complete with fixing instructions and Crack Monitoring Sheets to ensure professionals can consistently log long-term structural health trends.
