BONDCHECK

 

The BONDCHECK is a multi-mode bond testing flaw detector, providing high speed inspection in pitch-catch, resonance and MIA bond testing modes, with excellent defect sensitivity. All functions are  housed in a single lightweight instrument with a common user interface between the three modes, delivering a simple and intuitive operator led set up. A great all round asset for inspection in the laboratory or under cover as well as out in the field.

 

BondCheck BlueSc Fl 12cmEasy to use menus and icon system. 

The BondCheck menu system is simple and fast to navigate. It has the ability to add individually selectable soft key menu items to the sidebar for rapid function access and a “quick-setting menu” for easy set-up, review and adjustment.

With four operator selectable soft keys and a fifth slot for the last menu function used, technicians can quickly modify the system with their preferences. Each saved instrument setting can be associated with a unique, single press set of quick access soft keys. There are also two front panel hard keys that can be readily programmed for rapid single press access to frequently used functions.

 

Large, daylight readable, configurable colour screen.

The BondCheck has a large 14.5cm (5.7 Inches) LCD Colour Screen of 640 x 480 pixels providing the operator with excellent signal resolution and presentation together with the choice of configuring their own colour schemes and display types. It is easy to optimise the screen presentation regardless of the lighting conditions. A secondary pane can be configured to create a split screen display or an inset window, with a choice of X-Y spot, frequency sweep, RF waveform and Spectrum displays.
