RF4 RF-50M Professional Digital Video Microscope

RF4 RF-50M: A Professional Digital Video Microscope With Built-In Multimeter

The RF4 RF-50M is a professional digital video microscope that combines a 1080P camera, a 7-inch monitor and a multimeter controller in one bench unit. You see the board on screen, then touch the same joint with the test probes. No eyepiece strain, no second device, no cable shuffle. Pakistani repair shops handle dead phone, charging issue and display problem jobs all day, and many of those jobs end at a burnt pad, a lifted BGA ball or a shorted capacitor. This machine shows you the fault and lets you measure it from one position. Technicians who inspect, solder and test on the same bench get the most from it.

Key Technical Highlights

The camera records and displays 1080P video at 30 frames per second. The 7-inch display shows the board at 7X to 50X digital magnification, and you zoom continuously inside that range instead of stepping through fixed lenses. A 144 LED light unit floods the board with light, so small SMD markings and solder bridges stay readable. The package includes the monocular microscope, monitor, multimeter controller, remote control, adapter, test probes, HDMI cable and Type-C line. The body measures 380 x 260 x 430 mm and weighs 3.38 kg net. It sits on your bench beside your hot air station and soldering station without taking over the table. A power indicator and low battery tips keep you informed during long sessions.

Built-In Multimeter on the Same Bench

The multimeter controller measures resistance, DC voltage from 0 to 36V, AC voltage from 0 to 36V, diode, on-off continuity, capacitance and frequency. Use on-off mode to confirm a broken track before jumper lagana. Use diode mode to chase a short on a charging line. Check a suspect capacitor before you commit to IC change karna. Probe the joint while the magnified board stays on screen, so you place the probe tip exactly where you want it. Keep your standalone multimeters for deeper diagnostics. This unit covers the quick checks you repeat every hour, and that saves real time across a full day of boards.

Repair Workflow Fit

Start with inspection. Check the board for burnt pads, cracked ICs and corrosion before you apply heat. Move to soldering and rework. Watch BGA and SMD joints on screen while you work with your soldering station or hot air station, then verify the result under magnification before you close the job. Finish with testing. Probe the repaired line, capture a photo and keep proof for the customer. The machine suits CPU, IC, BGA and SMD work on mobile phone, iPad and tablet boards. It also helps on hardware fault jobs such as hang on logo and dead phone cases, where reflow quality and joint condition decide the result. Pair it with reballing kits, PCB holders and test boxes to build a complete bench.

On-Screen Tools That Save Time

The display software gives you three mouse pointer shapes: pointer, cross and gesture. The cross cursor offers off, ruler and centre modes. Eight configurable grid lines let you set direction, position, line width and colour, so you align a stencil or check pad spacing against a fixed reference. The marking function leaves reference points on screen while you work. Freeze modes split the display into full screen, left and right, up and down, or quarter screen, and you compare a good board against a faulty one side by side. Press the confirm button in the preview menu to take a photo or start a video. The IR remote controls zoom and capture without touching the unit, which keeps the image steady.

Why Technicians Choose This Machine

Shops with several benches buy it for one reason: it cuts tool switching. One unit replaces a separate camera, a monitor and a basic multimeter in your daily inspection routine. You document before-and-after results, show customers the fault and train junior technicians on a shared screen, all from the same hardware. If your work shifts toward eyepiece-based viewing, browse our Microscopes category for stereo options. Browse our Multimeters, Soldering Stations and Hot Air Stations categories to build the rest of your bench around it. For ISP and eMMC work, add our ISP Pinout Tools so you inspect the pads on this screen before you wire anything.
