The lightweight (only 5 ounces with battery) yet durable, portable Qnix 1200 measures the thickness of coatings (0-80 mils or 0-2000 microns) applied to ferrous substrates. Unique shape allows for easy one handed operation - no cables or plug-ins are required. The "V-groove" probe facilitates easier measurements along curved surfaces. Included 9v battery lasts for thousands of measurements, and gage features an automatic on/off for extended battery life. Accuracy is +/- 2% of the reading; gage conforms to ASTM D7091 and SSPC-PA2.
