This Tritex Multigauge 5600 outfit is supplied complete but without probes or probe cables. This would be ideal as a spare, or for surveyors who already have suitable probes and cables. All Tritex gauges are manufactured to, and comply with, the new standard of manufacturing Ultrasonic Thickness Gauges – BS EN 15317:2013. This standard covers the characterisation and verification of ultrasonic thickness measuring equipment to ensure they meet certain criteria of performance and build quality.
