Avongard is a UK company established in 1976. The joint founder of the company and now the Technical Director is a Chartered Structural and Civil Engineer and Chartered Surveyor who recognised the need for a simple but reliable calibrated gauge for the monitoring of cracks. Prior to that time, only crude qualitative methods or high-precision high-resolution instruments were available.
The Tell-Tales (generic name for crack gauges) supplied by Avongard are the original and genuine product. It is vital the products used for monitoring cracks are quality precision products. Great reliance is placed on the results of the monitoring, as the user may be liable if inappropriate remedial work is recommended based on the results of imitation products of inconsistent quality.
Users of Avongard products benefit from the following:
- All Tell-Tale products, including the Crack Width Gauge, are manufactured to conform to BS EN ISO 9002:2008 third party accreditation.
- The Tell-Tales and Crack Width Gauge are all manufactured from tough vandal-resistant polycarbonate renowned for its durability.
- Every product is supplied complete with a crack monitoring sheet and fixing instructions.
The caliper crack monitoring kit is supplied in a full kit complete with accessories. Included is a manual with advice on obtaining the best results using the caliper system. Only very high-quality calipers are supplied. Monitoring to a resolution in the order of 0.1 mm demands the highest quality instruments with good repeatability. Therefore, the calipers comply with EN61326:1997+A1:1998+A2:2001.
