System overview
When 9 antennas are attached to the cart type, the 3.2m wide lane can be measured twice.
Comparison with the conventional ME9200
The integrated rear radio wave absorber reduces variations in electric field strength due to reflection.
Since the antenna unit can be directly attached to the antenna fixing bar, the measurement preparation man-hours are reduced.

Standard specifications
Antenna
The standard is 9 pieces, and 3.2m wide lanes can be measured twice.≪Antenna spacing 20 cm≫.
- External dimensions:195(W)×105(D)×300(H)mm(excluding protrusions)
Cart
Equipped with a speed sensor, the measured distance is calculated automatically.
With 9 antennas installed, 3.2m wide lanes can be measured twice.
- External dimensions:700(W)×1000(D)×350(H)mm(when folded)
- External dimensions:700(W)×1000(D)×900(H)mm(when assembled)
Control Unit
It has a start SW and a SW that adjusts the zero point at the roadside machine position.
Requires DC12V or AC100V power supply. An AC/DC converter is included as standard.
- External dimensions:430(W)×450(D)×101(H)mm(excluding protrusions)
PC Software
It controls the control unit and immediately displays the measured electric field strength value in a graph or map diagram.
Electric field strength measurement example
The ME9200 software running on a PC controls the control unit to perform measurements, and automatically collects, analyzes, and displays data.
