The Dino-Lite AD7013MTL handheld digital microscope has a 5MP sensor in an aluminum alloy body, longer working distance, and an interchangeable nozzle feature. With up to 90x magnification depending on working distance and 2592 x 1944 of resolution; users will not miss any details. Included with this model are both the standard open faced nozzle as well as a sealed transparent cap nozzle designed to protect the lens and built in LED lights from dust, debris and moisture common to certain work environments. The removable nozzles also provide the user the option of increasing working distance when using the digital microscope without any nozzle installed. Having a Dino-Lite with longer working distance is great for applications that require a certain space between object and microscope to either work under or require a certain distance to view.
