    FAQs

    Q: What is the PROTECH QC3193?

    The QC3193 is a digital microscope with a 4.3-inch colour display that is intended for use in electronics, biology, jewellery, and hobby applications for the examination, analysis, and magnification of small objects. It can record videos, take pictures, and zoom digitally. For tasks that involve soldering, heat-shrinking, or component removal alongside inspection, you may also consider using the PROTECH TH1069 2000W Adjustable Heat Gun for a complete toolkit.

    Q: What magnification levels does it support?

    Depending on the lens and object distance, the QC3193’s magnification can be adjusted from roughly 20x to 200x. To get crisp clarity, use the focus wheel.

    Q: Does it have a built-in display?

    Indeed. With its 4.3-inch LCD, it may be viewed directly without a computer connection. Live pictures, taken pictures, and recorded videos are all displayed on the screen.

    Q: Can I inspect transparent or reflective objects?

    Indeed. To improve visibility and prevent glare, change the microscope’s angle and lighting intensity. If backlighting is available, use it for translucent items.

    Q: Can multiple users share the display at once?

    Indeed. A small group can see the 4.3-inch screen, but for bigger gatherings, use HDMI/AV to link the microscope to a monitor or projector.

    Q: Does it support measurement or calibration?

    Indeed. When linked to a PC, certain QC3193 versions come with software-based measuring tools that enable measurements of detected objects’ diameter, angle, and distance.

    Q: Can I record time-lapse or continuous observation videos?

    Depending on the microSD storage, several versions allow for continuous video recording. When connected to a computer, time-lapse may need additional software.

    Q: What is the effective working distance of the microscope?

    Depending on the magnification and lens configuration, the working distance usually varies from 30 to 100 mm. To keep clarity and focus, carefully adjust the distance.
