Bent Outside Calibration Tube For Concrete Air Meters

Bent Outside Calibration Tube for Concrete Air Meters

The Bent Outside Calibration Tube for Concrete Air Meters is a crucial accessory designed to verify the accuracy of your air meter, ensuring reliable and precise air entrainment testing in fresh concrete. This calibration tube is specifically engineered to meet the stringent requirements of AASHTO T152 and ASTM C 231 test methods, making it an indispensable tool for quality control technicians, engineers, and construction professionals.

Key Features and Functionality

This "J" or "U" shaped tube is filled with water and attached to the petcocks on the lid of a Type B concrete air meter. By introducing a known volume of water (representing a known volume of air) into the meter's chamber, you can verify that the gauge reading matches the expected value, typically 5%. This simple yet effective calibration check confirms the meter's accuracy before performing tests on fresh concrete mixes, preventing costly errors and ensuring compliance with project specifications.

Complete Your Concrete Testing Kit

Accurate concrete testing requires a full suite of reliable tools. We offer a comprehensive range of accessories to complement your air entrainment tests:

• Tamping Rods for Slump Cone Test: Featuring hemispherical tips, these rods are essential for properly consolidating concrete specimens during tests for slump, air content, and strength, as specified by ASTM standards.
• Concrete Strike-Off Bar: A straight and rigid bar necessary for removing excess concrete from the top of the air meter bucket or slump cone, creating a smooth and level surface for accurate volume measurement.
• Replacement Parts: Keep your equipment in peak condition with our high-quality replacement parts.
  • Replacement Gauges: Our durable, high-quality gauges are designed to fit most Type B Concrete Air Meters, ensuring you can always get a clear and accurate reading.
  • Replacement Air Pump: Featuring solid construction for extended service life, this air pump is compatible with Gilson Concrete Air Meters and models from other major manufacturers.
