Profile: Binks Industries, Inc. manufactures pinhole detectors. We produce several different pinhole detector models and offer optional ancillary equipment. Our pinhole detector function is to find holes as small as .001" in diameter in any opaque material, while the strip may be moving at speeds up to 5000 FPM, for classification and grading. The detector finds holes in material in widths from four to eighty four inches. The detector is a sturdy, low maintenance machine.
