QNix® 8500 Paint Thickness - Mil Gauge

QNix® 8500 Paint Thickness - Mil Gauge

This QNix® 8500 is our modular coating Thickness gauge for measuring coatings up to 200 mils (5000 microns) thick in many different environments. It can accommodate both standard and radio control / wireless probes that do not necessitate an extension cable. It is designed for easy operation, ready to use as no calibration is required for most applications. As a modular system, it comes in two Gauge body versions – basic and premium, with statistics function included in the later. With the QNix® 8500 Mil Gauge, the operator has the possibility of interchanging probes with a larger measurement range, for measuring thin coating thickness, as well as use the wireless probes for measurements at places that are difficult to access with bulky gauges. The QNix® 8500 DFT Gauge also has the capability of adjusting to various substrate properties via the use of single-point and two-point calibration. This capability allows the operator to take measurements on curved surfaces and small parts. Use the QNix® 8500 Thickness Gauge to take measurements on rough surfaces by defining a compensating roughness and assigning a virtual point on the rough surface. Its combined measurement mode employs two measurement methods in one procedure. This combined measurement takes - for example, individual thicknesses of paint and zinc layers in a duplex coating system. This is a typical coating system in the corrosion protection industry, as double coatings are deemed superior in terms of protection. Download User Manual QNix 8500
