Rapid results
The loud audio signal helps locate rebars
quickly and precisely. Scan large areas without the need to constantly
watch the meter.
Industry leading accuracy
The directional search head
locates rebars, establishes their direction and measures cover with great
precision even at very close centres.
Strength and reliability
Designed and built to withstand
daily use in the toughest conditions. Thousands are in use in construction
sites around the world. Weatherproof to IP54.
Versatility
The CM9 accepts a large head for reading of
abnormally deep cover up to 200mm.
CM9 CoverMaster is the first cover meter to give the position, direction, cover and diameter of reinforcing bars in concrete, all at the same time.
The cost of traffic management on motorways and major roads, and the expense of access equipment for testing buildings was a deciding influence in Protovale's decision to make the CM9 CoverMaster a cover meter that would be very fast and accurate to use in noisy, dark conditions, frequently with difficult access.
