SUPARULE CHM300DT 線纜測高儀
· Fast measurement
· Inherently safe
· High accuracy
· Easy to use
· Proven reliability
· Compatiable with DT80
DESCRIPTION：
The SupaRule CHM 300DT Cable Height Meter is a handheld meter for measurement of cable sag, cable height distance, and overhead clearance of conductors. It is a modern alternative to escopic measuring poles. The CHM 300DT Meter utilises ultrasonic signals to determine the height of overhead cables up to 15m （50feet） Used by line operators within the utilities industries, e.g., electricity and ecommunications, the CHM300DT measures the height and separation of up to 3 wires.
The CHM300DT has the additional feature of measuring horizontal distances up to 150 feet （45m）, with the aid of the optional Dynamic Target（DT80）.
APPLICATIONS：
Applications include height measurement of:
- ephone lines
- Distribution lines
- Transmission lines
- Cable evision
- Street lighting
- SAG （lowest point to ground）
- Pole Span
- Distance measurement across busy roadways
- Clearances on construction sites
