Overview
AR-300PF density tester is an AR series product launched by DAHOMETER brand based on multi-year density measurement technology. It is designed through functional simplification, structural optimization and enhanced practicality. The instrument has the characteristics of good measurement Repeatability, high accuracy and simple operation. It is mainly used for density testing of Encasement materials, sponges, foams, thermal insulation materials and other materials.
Features
1. Suitable for sponge, foam and other types of product measurement
2. Simple to operate and easy to use
3. Fast measurement and stable performance
4. With fixed volume density measurement function
5. Equipped with a large-capacity PC material sink
6. Use of Water or Miscellaneous Liquids as Medium
7. With actual water temperature compensation function
8. Equipped with a special windproof and dust cover
9. Can be adapted to various places such as workshops and laboratories
Principle
The density tester is based on the principle of Archimedes drainage method. By measuring the weight difference of the sample in the air neutralizing immersion in the liquid medium, combined with the medium density and actual water temperature compensation, the density, volume, open Pore volume, closed Pore volume, closed gap rate, water absorption rate and other related parameters of the sample are calculated.
Applications
Encasement materials, cushioning materials, sponge, foam, thermal insulation materials, protective materials, shoe materials, underwear, automobiles, sports and sports equipment, furniture woodworking enterprises, children's cars, polymers, shock-proof materials, New materials research laboratory
Standards
GB/T6343、GB/8810、GB/T2669、GB/T10799、GB/T1033、ASTM D 3574、JIS
Steps
1. Preheat the machine and ensure that the instrument is placed horizontally
2. Select the appropriate measurement medium (such as water) according to the sample characteristics and inject it into the sink
3. Perform single-button automatic correction
4. Set the actual water temperature, medium density and other parameters
5. Place the sample on the measurement platform and weigh it in air
6. Immerse the sample in the medium and weigh it in water
7. The instrument automatically calculates and displays the results of density, volume, opening rate, closed cell rate, water absorption rate, etc
Notice
• Before use, make sure the instrument is placed on a smooth and level surface
Do not exceed the maximum capacity line of the sink when injecting measurement medium
• Water temperature compensation should be set according to the actual medium temperature before measurement
• When the sample is immersed in the medium, ensure complete immersion and no bubble adhesion
• When using non-aqueous media, it is necessary to accurately enter the medium density value in the parameter setting
• Regularly clean the measurement platform and sink to keep the instrument clean and drying
Avoid use in environments with strong electromagnetic interference or severe vibration
• Please turn off the power and cover the windproof and dust cover when the instrument is not in use
