The Proportional Caliper Device<\/b> is a vital instrument for evaluating the shape characteristics of coarse aggregates. Specifically, laboratory technicians use this tool to determine the percentage of flat particles, elongated particles, or flat and elongated particles in a sample. Since aggregate shape directly impacts the workability and strength of concrete and asphalt mixes, the Proportional Caliper Device<\/b> provides the data necessary for high-quality construction projects.<\/p>\n
Furthermore, the design of this apparatus allows for rapid and accurate manual testing. Because the device utilizes a fixed ratio system, it simplifies the comparison of a particle’s length to its width or thickness. Consequently, the Proportional Caliper Device<\/b> ensures that your laboratory results remain consistent and repeatable. Therefore, quality control professionals rely on this equipment to maintain strict compliance with international engineering specifications.<\/p>\nRugged Engineering and Functional Design<\/b><\/h3>\n
In addition to its accuracy, the Proportional Caliper Device<\/b> features a heavy-duty construction designed for the demanding laboratory environment. We manufacture the base plate from high-quality, reinforced materials to prevent warping or movement during use. Moreover, the pivoting arm and adjustable pins consist of durable plated steel to resist wear from abrasive aggregate samples. Because accuracy is paramount, the Proportional Caliper Device<\/b> maintains its alignment even after thousands of measurements.<\/p>\n
The operation of the unit is remarkably straightforward. First, the user sets the desired ratio, such as 1:2, 1:3, or 1:5, by adjusting the position of the pivot pin. Next, the operator places the largest dimension of the aggregate between the fixed and swinging posts. Finally, the technician checks the smaller dimension against the smaller opening of the Proportional Caliper Device<\/b>. As a result, this mechanical method offers a clear, physical pass\/fail assessment for every particle tested.<\/p>\nWhy Choose the Cantrol Proportional Caliper Device?<\/b><\/h3>\n
Using a high-precision Proportional Caliper Device<\/b> minimizes the subjectivity often associated with manual shape assessments. Many pavement failures occur due to an excess of thin or brittle aggregate particles. However, by\u00a0using the Cantrol\u00a0Proportional Caliper Device<\/strong>, you can effectively screen materials to meet the requirements of ASTM D4791<\/span>. In conclusion, this tool is a cost-effective, highly reliable solution for any facility focused on superior aggregate testing and pavement design.<\/p>\n Multiple Ratio Settings:<\/b> Easily adjusts to measure ratios of 1:2, 1:3, 1:4, and 1:5 for versatile testing.<\/p>\n<\/li>\n Standard Compliance:<\/b> Fully meets the requirements for ASTM D4791 and other departmental transport standards.<\/p>\n<\/li>\n Durable Construction:<\/b> Features a heavy-duty base and plated steel components for maximum longevity.<\/p>\n<\/li>\n Precision Pivot System:<\/b> Smooth-action swinging arm ensures accurate measurements without mechanical play.<\/p>\n<\/li>\n Rapid Assessment:<\/b> Designed for high-speed manual sorting of coarse aggregate samples.<\/p>\n<\/li>\n Stable Base Plate:<\/b> Wide footprint prevents slipping or tipping during repetitive laboratory use.<\/p>\n<\/li>\n Low Maintenance:<\/b> Requires no calibration software or power source, making it ideal for field or lab use.<\/p>\n<\/li>\n<\/ul>\n <\/p>","protected":false},"excerpt":{"rendered":" Use to determine the percentage of flat particles, elongated particles, or both flat & elongated particles in coarse aggregates<\/p>","protected":false},"featured_media":12906,"comment_status":"open","ping_status":"closed","template":"","meta":{"inline_featured_image":false},"product_brand":[],"product_cat":[400,427],"product_tag":[937,938,922,939,936,940,935,941],"class_list":["post-12647","product","type-product","status-publish","has-post-thumbnail","product_cat-aggregate","product_cat-aggregate-angularity-elongation","product_tag-aggregate-shape-test","product_tag-astm-d4791-caliper","product_tag-cantrol-lab-equipment","product_tag-coarse-aggregate-analysis","product_tag-flat-and-elongated-particles","product_tag-pavement-material-testing","product_tag-proportional-caliper-device","product_tag-shape-consistency-tool","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"\n\u00a0Product Features<\/b><\/h3>\n
