M 7—Ultra-portable designed clad alignment splicer

The INNO Instrument M 7 is an active, clad alignment splicer with an ultra-portable design, and is one of the most efficient fusion splicers on the market.

Despite its compact design and light weight, the M 7 has virtually all the powerful features for which INNO Instrument has become known for. Documentation images are captured at 400 × magnification. This allows for extremely detailed inspection on the high-resolution 4.3-inch color LCD screen.

The easy-to-use interface is intuitively designed; zooming in and out, for example, is as simple as a double tap. 2 bright LEDs ensure comfortable working even in low light conditions.
