The Suparule 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 telescopic measuring poles. The Suparule Cable Height Meter utilises ultrasonic signals to
determine the height of overhead cables up to 23m
(75feet).
Used by line operators within the utilities industries,
e.g., electricity and telecommunications, the CHM190
measures the height of a single wire, the CHM300 and
CHM300E measure up to 3 wires, while the CHM600
and CHM600E models measure up to 6 wires.

• Range (25mm cable min):  3 –23m (10-50ft)
• Range (12mm cable min):  3 –15m (10-50ft)
• No. of wires measured:6
• Accuracy:  0.5% ± 2 digits
• Resolution (range <10m): 5 mm
• Resolution (range >10m): 10 mm
• Minimum gap between wires: 150 mm
• Operating Temperature Range: -10°C to 40°C
• Battery Life (Long Life Alkaline type): 50,000 measurements
• Measurement units: Imperial (feet/inches) or metric (meters)

Applications include height measurement of:

• Telephone lines
• Distribution lines
• Transmission lines
• Cable television
• Street lighting
• SAG (lowest point to ground)
• Clearances on construction sites
