Toyo Keiki VF-11M Series Wide Angle Meter

Toyo Keiki

Product Made In Japan
Manufacturer: Toyo Keiki
Model: VF-11M Series

Features

1. A long scale meter for indicating wide angles.
2. A stepped scale plate removes any level difference between the scale and the tip of the needle, resulting in accurate readings.
3. Meter that has a bright scale due to the wide-cover lighting surface.
4. It is not affected by steel panels.
5. Can be manufactured with EL board (Electro-Luminescence Board) lighting.
6. The terminal cover is now equipped as standard.
7. It is now compatible with multi-setting set pointer models.
