Efficient tracking The gap monitor uses two panels and a transparent top plate to deliver an innovative measurement design. The slim wire cursor moves in proportion to the scale, capturing precise data on gap openings and closings. Results are recorded on the included protocol sheet when two nails are removed. High precision and measurement range Achieve high precision with a 0.5 mm (0.02 in) resolution. Horizontal range: 20 mm (0.79 in); vertical range: 10 mm (0.38 in. The XY scale is 1 mm (0.04 in) per division, and the scale wire enables accurate and optimized measurements for inspection requirements. Portable and easy to use Redesigned mounting posts allow precise placement without glue or complicated steps. Improved stability and a user friendly design make attaching two plates effortless and convenient. Advanced materials and readability Constructed from high quality ABS and acrylic to ensure durability and stable data reading.
