The Multigauge 5300 GRP thickness gauge is a simple, robust ultrasonic thickness gauge designed to check the condition of Glass Reinforced Plastic (GRP) or Engineering Plastics. It can also be used on uncoated metal. It uses a single crystal probe for accuracy and an increased measuring range. The easy to use keypad allows operator interface, whilst the bright colour LCD display can be used in all light conditions. The moulded soft rubber surround feels comfortable, looks good and provides extra protection against knocks and scrapes. All probes have Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge at the same time as transmitting recognition data – the result is a perfectly matched probe and gauge for enhanced performance.

All gauges are supplied with as complete kits with a 19mm 1MHz probe (2 – 150mm measuring range).
