Absolute Manometer: Digital Pressure Measurement

Digital Absolute Pressure Manometer

The Digital Absolute Pressure Manometer is a must have for accurate vacuum measurement in laboratory settings, especially for asphalt testing. Used in the USA, this manometer is safe, precise and environmentally friendly for vacuum measurement, a must have for professionals in the asphalt testing industries.

Product Description:0 to 10 VDC analog output signal is linear with pressure.

Advanced Measurement Technology:

  • Measurement: Measures absolute pressure from 0 to 1,000 mm Hg with 0.1 mm resolution for laboratory applications like asphalt Rice Test. Can measure up to 10 torr for specific applications.

  • Accuracy: ±0.5%. Accuracy is defined as a percent of reading.

  • Digital Display: Backlit digital display for instant reading, reduces errors during testing. Can be interfaced with computers for data logging.

For measuring air content in concrete reliably, consider the Watts Press-Ur-Concrete Air Meter ASTM C231.

Safe and Environmentally Friendly:

  • Mercury-Free Design: Mercury free construction, safer for laboratory use and reduces environmental impact. Complies with safety regulations in USA and internationally.

  • Absolute Pressure Transducer: Advanced pressure transducer for accurate and digital reading. Nickel alloy construction for steam and deionized water resistance.

Versatile Power Options:

  • Power Supply: 9V battery or AC adapter (both included). Automatic shut off when not in use. Powered by ±15 VDC input voltage.

Dimensions and Specifications:

  • Product Dimensions: 3.1 x 6.5 x 1.18 inches (78.7 x 165.1 x 30 mm) WxDxH

  • Electrical Requirements: 115V / 60Hz and 230V / 50Hz power systems. Note part number and model number for easy identification.

Applications and Compliance:Meets the requirements of:

  • AASHTO T209: Standard Method of Test for Theoretical Maximum Specific Gravity and Density of Hot Mix Asphalt (HMA).

  • ASTM D2041: Standard Test Method for Theoretical Maximum Specific Gravity and Density of Bituminous Paving Mixtures.

For a comprehensive understanding of these methods, refer to the guide.

For those interested in broader asphalt testing methods, consider exploring asphalt viscosity tests, which are crucial for assessing the quality and performance of paving materials.

Includes:

  • Digital Absolute Pressure Manometer, 115V/60Hz

  • Hose Barb Connection with Needle Valve: For easy connection to vacuum tubing.

  • AC Adapter and 9V Battery: For different laboratory environments.

Add to your pressure manometer:

  • 4,000g and 6,000g Pycnometers: For asphalt specific gravity measurements, meets ASTM D2041/AASHTO T209.

  • Adapter Set for 6,000g Vacuum Pycnometer: For use with SG-15 Pycnometer and Rice Shaker.

  • Filter Flasks : Heavy-walled, ASTM and AASHTO compliant, used as Pycnometers for weighing in air.

  • Le Chatelier Flask: For specific gravity determinations of hydraulic cement and fine materials.

  • Jar and Top for Specific Gravity & Absorption of Fine Aggregate: For calculating the volume occupied by fine aggregates.

  • Volumetric Flask: For specific gravity testing of soils and aggregates.

  • Flask Adapter Set: For running tests using Flasks and Mason Jar Pycnometer (SG-2).

  • Digital Residual Pressure Manometer: Measures applied vacuum during testing, NIST certified models available.

  • AutoRice Digital Manometer and Controller System: For precise control of vacuum pressure.

  • Alternate Clamping System and EZ-Clamp Upgrade Kit: For older Gilson Rice Shakers to EZ-Clamp system.

  • Clear Vinyl Tubing: 1/4 or 3/8 inches for pycnometers.

  • Hose Clamp : Adjustable for flow through vinyl tubing.

  • Step-Up/Step-Down Transformer: 500W for Rice Shaker on 230V/60Hz.This digital pressure manometer is a safe and easy way to measure vacuum pressure, perfect for asphalt Rice Testing in the USA. Mercury free, accurate and user friendly, it’s a great choice for labs that value safety and precision. With many accessories, the Digital Absolute Pressure Manometer is a versatile tool for many testing applications.

For comprehensive soil testing, including measuring shear strength in various soil types, consider the AMS 59020 Field Vane Shear Tester Kit.

Key Features and Benefits

Digital manometers can measure absolute, differential or gauge pressure with high accuracy often up to 0.05%. They have graphical displays and data logging, so you can store and review pressure readings over time. The benefits of digital manometers are reliability, compact design and can operate in any chemical environment due to their robust construction, often made from nickel alloy or similar materials. This makes them ideal for labs, calibration facilities and many industries that require precise measurements.

Principles

Pressure principles involve the use of sensors that convert pressure into an electrical signal. In capacitance manometers such as the MKS 626D Unheated Absolute Baratron Capacitance Manometer, the basic sensor operates on the principle of capacitance change in response to pressure variations. This change is then converted into an analog output, usually a 0-10 VDC signal, proportional to the pressure. The accuracy of these measurements can be affected by gas type and contaminants. Understanding these principles is important to choose the right manometer for your application and to ensure long term output stability.

Digital Communication

Digital manometers often have digital communication options so you can connect the instrument to a computer or other device for data logging, analysis and storage. These options may be IR serial ports, USB connections or other digital interfaces to transfer pressure readings to a PC for review and analysis. The ability to expand data logging as seen in the Meriam ZM2000 Absolute Manometer with Data Log Pro feature makes digital manometers more useful in both lab and field applications.

Calibration and maintenance are key to ensuring the accuracy of digital manometers. These instruments should be calibrated regularly against known standards to verify their accuracy. Maintenance may involve checking the sensors for damage or contamination, ensuring all connections are secure and the operating environment is within the specified parameters for the manometer. Proper care and maintenance can prevent system failures, ensure repeatability of measurements and extend the life of the instrument. Also understanding the full scale range, overpressure limit and other specifications of the manometer is important for its proper use and maintenance, so it operates within its design parameters and gives the best possible accuracy in pressure measurement. For those interested in humidity measurements, selecting the best thermometers can be equally important for ensuring accuracy in various environments.
