Overview
AR-250PM density tester is a new series of products launched by DAHOMETER brand based on multi-year density measurement technology through functional simplification, structural optimization and practicality enhancement. The instrument has the characteristics of good measurement Repeatability, high accuracy and simple operation. It is mainly aimed at magnetic materials, precision Pottery and porcelain, powder metallurgy, pneumatic tools, automotive parts, mechanical parts, MIM injection, friction materials and New material research laboratories.
Features
1. Any porous shape can be measured instantly
2. Anyone can easily operate it
3. Fast measurement, good stable performance
4. Use water as a medium, and other liquid media can also be used
5. Large capacity PC material sink
6. With actual water temperature compensation function
7. Equipped with a special windproof and dust cover
8. Suitable for on-site and laboratory rapid testing and other places
Principle
The density tester works based on the principle of Archimedes drainage method. By measuring the weight of the sample in air and immersed in a liquid medium (such as water), combined with the density of the liquid medium, the density of the sample and related physical parameters are calculated. The instrument has a water temperature compensation function to ensure the accuracy of measurement at different environment temperatures.
Applications
Magnetic Materials, Precision Pottery and porcelain, Powder Metallurgy, Pneumatic Tools, Automotive Parts, Mechanical Parts, MIM Injection, Friction Materials, New materials research laboratory
Standards
ASTM B311、ASTM B328、GB/T5163、JIS Z2505、JIS Z2506、MPIF Standard42、MPIF Standard45
Steps
1. Turn it on to warm up and make sure the instrument is placed horizontally.
2. According to the characteristics of the sample, select or set the water temperature, measurement medium density, etc. in the parameter setting.
3. Place the sample on the measurement platform and weigh it in air.
4. Immerse the sample in a measurement tank with a liquid medium (such as water) and weigh it in water.
5. The instrument automatically calculates and displays the results, such as apparent density, volume density, Porosity, etc.
6. After the measurement is complete, remove the sample and clean the measurement platform and sink.
Notice
• Please ensure that the instrument is placed smoothly and horizontally before use.
• Correctly set water temperature and medium density parameters according to measurement requirements.
• When immersing the sample, ensure that the sample is completely immersed and free of bubbles.
• After measurement of different samples or replacement of media, please clean the sink and measurement platform in time.
• Power supply voltage (AC100V~ 240V 50HZ/60HZ).
• The windproof dust cover of the instrument configuration should be used during measurement to reduce environment interference.
• Periodic single key calibration to ensure Measurement accuracy.
