PZCC's acrylic crack monitoring gauges are designed to measure and track the development of cracks on flat surfaces. Made from high-quality acrylic material, these gauges are robust, waterproof, and resistant to sunlight, wear, and scratches, making them ideal for repeated use. Each gauge measures 10 cm long, 3 cm wide, and 0.9 cm high, weighs 0.3 kg, and is easy to install and read thanks to its intuitive design. The instrument consists of a graduated plate and an indicator plate, allowing for monitoring of horizontal and vertical crack movement. It is particularly useful for observing the opening and closing of cracks, as well as misalignment, on the surface of various buildings. Additionally, it can monitor the relative displacement between two points in both horizontal and vertical directions. This product is widely used in the construction industry to ensure reliable detection and monitoring of changes in crack width or length over time. Please note that due to manual measurement, a measurement deviation of 1 to 3 cm may occur, and the actual color of the item may differ slightly from what is shown due to variations in display and lighting.
