Innovative design for precise tracking The slot monitor features a transparent top and dual panes to enable accurate tracking of slot openings and closures. Data is stored on the provided data sheet using the fine-wire slider and the removal of two nails. Precision and range you can rely on Achieve a measurement resolution of 0.5 mm (0.02 in). Horizontal travel is 20 mm (0.79 in) and vertical travel is 10 mm (0.38 in. It includes a 1 mm XY scale and a measurement wire to support high precision readings. Portable and easy to mount Designed for portability and ease of use with redesigned mounting posts. You can achieve precise placement without glue or complex steps. The improved stability and user friendly design make mounting two plates quick and convenient. Durable materials and clear data readout Constructed from high quality ABS and acrylic, providing durability and stability. The material selection also allows easy data readout for reliable measurements. Use scenarios - Fixture alignment and calibration in manufacturing or assembly lines, where precise tracking of slot openings is required. - Prototyping and design validation in labs, enabling documented tolerances and repeatable measurements. - On site installations or field service where quick, glue-free mounting and stable readings are needed for secure plate alignment.
