SELN-121BM (JAPAN version) Wireless 2-axis type digital spirit level

This wireless digital level is a compact and lightweight level that has been used for many years in the semiconductor manufacturing equipment industry.
It can be used for measurement even in locations with weight and space limitations, such as on a robot arm.
The wireless system allows the user to check the level on a monitor at a distance from the measurement surface.
This product can measure 2 axes (X and Y axes) at the same time, leading to a reduction in man-hours.
A wired type is also available (Model: SELN-001B).
You can choose either wired or wireless type depending on your application.

Features

01 This is a powerful tool for level measurement in areas where a level cannot normally be placed. It can also be used on a robot arm!

02 Allows level adjustment while checking the monitor at a position away from the measurement surface.

03 Enables level observation of areas with narrow vertical spacing.

Enables level observation of areas with narrow vertical spacing.
