The Unigraf VLM-333 is a hand held RGB video level meter that simultaneously measures and displays all three components of a video RGB signal.
Designed with an accuracy of better than 0.3%, the VLM-333 can quickly and easily measure the video levels wherever and whenever necessary.

Measure RGB video levels accurately, in less than 10 seconds!

The expansion of colorful digital communication sets new demands for color monitor performance. Effective quality work presumes frequently performed checks of video signals in your color monitor.

The Unigraf VLM-333 is the right solution for fast and easy measurements of RGB and monochrome signal levels anywhere and any time.

No extra time-consuming adapters or works are needed, simply connect to the monitor signal source and read the result.

The Unigraf VLM-333 is a hand-held instrument designed for measuring the amplitude level of an analog RGB or monochrome video signal, i.e. the difference between the voltage levels representing black and white.

The VLM-333 has both BNC and 15 pin HDD (VGA) connectors for RGB inputs. The video levels are displayed on the LCD display as a digital readout, in millivolts.

The meter is battery powered for portable use or it can be powered by an external power adapter for continuous operation.

The VLM-333 accepts a wide range of input voltages: (DC at 6.5 to 12 volts or AC at 7.5 to 12 volts, 50 or 60 Hz).
