The 2D Video Precision Measuring
System use CCD to display the material image on
the screen or monitor, which may make up for the
deficient measuring technique for overhead projectors.
The EFA2008 controller, featuring automatic data
input and reporting of data output, improves the
operating and measuring procedures for overhead
projectors. In particular, the special design of
active hairline greatly increases the measuring
Operating easily, every one can use it without difficulties.
You don’t have to spend your spare time and money
to learn how to use the measuring instruments. The
modern instrument, Video Precision Measuring System,
is very expensive. To promote measuring technique,
the prices of series of EFA products are set to
be reasonable and acceptable so that ordinary businesses
can afford to have those kinds of apparatus to enhance
the measuring quality.

- Outline measuring
- Ease of operating interface
- No need to purchase PCs
1. When measuring
with traditional projector, you have to place
the material upright and aim at the screen. But
with EFA, you need not to place the material upright,
so you can save lots of time and avoid the error
resulting from upright accuracy
2. With the features of real time drafting and
measuring, the output graph can be combined with
AUTOCAD, and the measuring data can be exported
to EXCEL worksheets.
3. Can measure the diameter and coordinates of
the center of a circle, the long and short axis
distance of an ellipse, the length and angle of
a line section, radius of an arc, coaxial angle;
the thread of a screw (distance, depth, inner/outer
radius, intersection angle).
4. Can measure angle, the distance between a point
and a line, an intersection point of two extended
lines, an intersection arc of two lines (special
smart angle R), the distance between two circles,
the distance between a circle and a line (distance
of centers, shortest distance, longest distance),
distance between two points, and distance between
two parallel lines.
5. Built-in SPC analysis reports (qualified rate
statistics, measuring data chart)
6. Directly draw and edit on the controller, so
you can immediately obtain varied sizes and graphs.
