Product Description
Used to determine grade of bitumen. The penetration tests determine consistency of bitumen for the purpose of grading. Depth in units 1/10 of millimeter to which a standard needle having a standard weight will penetrate vertically in a duration of five seconds at a temperature of 25C determines penetration for gradation.Specification: It consists of a vertical pillar mounted on a base provided with leveling screws. The head, together with dial plunger rod a cone (or needle) slides on a pillar and can be clamped at any desired height. A rack and pinion and pointer assemble provides fine adjustment of needle or cone tip to sample. It incorporates a clutch mechanism. Which makes reading of penetration and subsequent resetting a simple and accurate operation? The dial is graduated in 400 1/10 and the millimeter subdivisions and the needle pointer against figures makes easy reading.Supplied with a bitumen penetration needle, ring weight one each 50 gms. and 100 gms. two sample containers Precision and Versatility for LaboratoriesEngineered for laboratory use, this Standard Penetrometer is tailored to meet the needs of professionals assessing bituminous materials. Its sturdy build and combination of high-precision dial gauge with fine least count ensure reliable consistency measurements under varied conditions.
User-Friendly FeaturesThe penetrometer is designed for ease of use with a push-button release mechanism and adjustable height options. Its portable carrying case and spare plunger enhance flexibility, allowing convenient operation and transport between laboratory settings.
FAQ's of Standard Penetrometer:
Q: How is the Standard Penetrometer used to determine bituminous material consistency?
A: To determine the consistency of bituminous materials, place the sample on the penetrometer's base, position the 10 mm plunger, and use the push-button release to allow the weighted plunger to penetrate the sample. The dial gauge then displays the penetration depth in millimeters, providing an objective consistency measure.
Q: What are the advantages of the adjustable height and push-button release mechanism?
A: The adjustable height ensures precise positioning of the plunger for different sample sizes, while the push-button release enables controlled, reproducible testing. This design enhances accuracy and repeatability in consistency measurements.
Q: When should the spare plunger be used, and how is it replaced?
A: The spare plunger is included for convenience in case of wear or accidental damage to the original. To replace, simply detach the used plunger and secure the spare in its place, ensuring uninterrupted laboratory testing.
Q: Where is this penetrometer commonly employed?
A: This penetrometer is primarily used in laboratories dedicated to material testing-especially for bituminous substances-by distributors, exporters, manufacturers, suppliers, and traders involved in construction and quality control industries.
Q: What benefits does the included carrying case offer?
A: The sturdy carrying case protects the penetrometer and its accessories during storage and transportation, reducing the risk of damage and making it easy to move the instrument between work sites or laboratory stations.
Q: How does the dial gauge ensure testing precision?
A: The dial gauge features a measuring range of 0-25 mm and a least count of 0.01 mm, enabling users to obtain finely resolved, precise penetration measurements crucial for detailed consistency analysis.
