When the visual indicator (rifle scope or LED) is centered, the probe is directly over the rebar.
The is a classic eddy current pulse induction instrument designed for the non-destructive location of reinforcing bars (rebar) and the measurement of concrete cover depth. While succeeded by advanced digital units like the Profometer PM-8000 or PM-600 , the Profometer 4 remains a staple for on-site quality control due to its reliability. 1. Core Measurement Principles
Accuracy in cover measurement depends on the input bar diameter. If the diameter is unknown, the device can provide an estimation once positioned directly over the bar. proceq profometer 4 manual
Hold the probe in the air, away from any metal objects, and press the Zero button. This calibrates the device to the current environmental conditions.
Before beginning any investigation, ensure you are not wearing metal jewelry or watches, as these can interfere with the magnetic field. When the visual indicator (rifle scope or LED)
The center line of the probe indicates the precise location of the rebar. 2. Essential Operating Steps
Used to map a grid of reinforcement over a larger rectangular area, producing a "heat map" of cover depths. Hold the probe in the air, away from
The Profometer 4 operates on the . A coil in the probe is energized by a current pulse, creating a magnetic field. When this field encounters a metallic object like a rebar, it induces eddy currents, which in turn generate a secondary magnetic field. Precision: It typically offers an accuracy of
