Overview
DAHOMETER AR-150VM density tester is a new series of products based on the brand's multi-year density measurement technology through functional simplification, structural optimization and enhanced practicality. The product has the characteristics of good measurement Repeatability, high accuracy and simple operation. It is mainly aimed at the research and laboratory application of new materials such as vulcanized rubber, sealing rubber, porous sponge, porous metal and Pottery and porcelain.
Features
1. Direct reading of measurement results without calculation.
2. Accurate and reliable measurement, easy and fast operation.
3. Samples of any shape can be measured.
4. Saturation medium density can be freely set.
5. Use water as the measurement medium, other liquid media can also be used.
6. With actual water temperature compensation function.
7. Equipped with a special windproof dust cover.
Principle
The density tester uses the Archimedes principle buoyancy method for measurement. By measuring the mass of the sample in the air and the buoyancy in the liquid medium, the density and volume change rate of the sample are calculated.
Applications
Vulcanized Rubber, Forced Oil Seal, Sealing Rubber, Expanded Rubber, Oil Ring Rubber, O Ring Rubber, D Ring Rubber, V Ring Rubber, Forced Rubber, Oil Seal Rubber, Porous Sponge, Porous Metal Materials, Porous Pottery and porcelain, Metal sealing, New Materials Research Laboratory
Standards
Density measurement conforms to: ASTM D792, ASTM D297, GB/T533 standard; Rubber expansion rate measurement conforms to: GB/T18173 standard; Water absorption measurement conforms to: GB/T 8810-2005 standard
Steps
1. Preheat the machine and set the water temperature and measurement medium density.
2. Place the sample on the measurement table and weigh it in air.
3. Immerse the sample in a liquid medium in a water tank and weigh it.
4. The instrument automatically calculates and displays the results of density, mass change rate, volume change rate, water absorption rate, etc.
Notice
• Power supply voltage in the range of AC100V~ 240V and use matching plug.
• Before measurement, compensation should be set according to the actual water temperature to ensure Measurement accuracy.
• The density of the saturated medium can be freely set as required.
• The measurement medium is not limited to water. Miscellaneous liquids can also be used, but their density values need to be set accordingly.
• Use a windproof dust cover configured to reduce environmental interference with measurements.
• Do not exceed the maximum weighing limit of 150g.
• Keep the sink and measurement platform clean to avoid affecting the measurement results.
• The measurement time varies from sample to sample and is usually about 10 to 60 seconds.
