Concrete Air Meter Calibration, Digital Gauge with Certificate

Concrete Air Meter Calibration: Digital Gauge with Calibration Certificate

AR-B air meter is a heavy duty, highly accurate and long lasting upgrade for most popular Type B Concrete Air Meters. Calibrators are essential tools for verifying the accuracy of pressure-type concrete air meters, providing immediate results and helping technicians avoid accuracy disputes. Features not found on lower quality gauges are wide-profile phosphor bronze Bourdon tube and rugged mechanism for accuracy. Fine adjustment screws on the dial face are micro-adjustable for easy calibration “tweaks” saving time and making calibration and maintenance easier. ±1/2% of full scale.

Digital Gauge displays psi applied up to 60PSIG and % air content of sample, ±0.25% of full scale. American made gauge has IP67 weatherproof enclosure with rubber boot and backlit LCD display. Powered by 2 AA batteries, battery level displayed on screen. 2.5in (64mm) diameter gauge face is polycarbonate and ABS plastic with IP67 waterproof enclosure. 1/4in NPT connection fits most concrete air meters.

Accessories to Concrete Air Entrainment Test: Concrete Air Meter

Slump Cone Test Tamping Rods have hemispherical tips and are included in complete kits for concrete air meters. These rods are critical for air content measurement in concrete so they are important for operation and function of air meters used for concrete testing

Tamping rod is used when consolidating concrete specimens for tests that include slump, air content and strength, so the tamping rod is used for specific tests related to air measurement in fresh concrete.

Concrete Strike-Off Bar is used to remove excess fresh concrete material.

Concrete air meters are essential tools in the construction industry, used to measure the air content in concrete mixes. Accurate calibration of these meters is crucial to ensure the quality and durability of concrete structures. In this article, we will discuss the importance of concrete air meter calibration, its benefits, and the calibration process.

Features and Benefits

Concrete air meters are designed to provide accurate measurements of air content in concrete mixes. The features of these meters include a water-filled base, a pressure gauge, and a calibration vessel. The benefits of using concrete air meters include:

• Improved accuracy in air content measurements, ensuring that the concrete mix meets the required specifications.

• Enhanced durability and quality of concrete structures, reducing the risk of structural failures.

• Reduced risk of damage to concrete due to incorrect air content, which can lead to issues such as cracking and reduced strength.

• Increased efficiency in concrete testing and quality control, allowing for quicker and more reliable assessments of concrete quality.

Calibration and Verification

Calibration and verification of concrete air meters are critical to ensure their accuracy and reliability. The calibration process involves checking the meter’s gauge accuracy, verifying the initial pressure line, and calibrating the meter using a calibration vessel. Regular calibration helps maintain the precision of the air meters, ensuring consistent and reliable measurements.

Calibration Process

The calibration process for concrete air meters involves the following steps:

1. Check the gauge accuracy by verifying the initial pressure line and ensuring that the gauge hand indicates 0.0±0.1%.

2. Verify the calibration vessel’s capacity and ensure that it matches the manufacturer’s specifications.

3. Fill the calibration vessel with water and attach it to the meter.

4. Pressurize the air chamber by pumping until the gauge needle stabilizes at the initial pressure line.

5. Record the calibration data and ensure that it meets the manufacturer’s specifications.

Calibration Certificate

A calibration certificate is issued after the calibration process is completed. The certificate includes the following information:

• Meter serial number and model number

• Calibration date and due date for re-calibration

• Calibration data, including gauge accuracy and initial pressure line verification

• Manufacturer’s specifications and tolerances

• Signature of the calibrator and date

This certificate serves as a formal record of the meter’s accuracy and ensures that it meets the required standards for reliable concrete testing.
