Overview
AR-150PF 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 used for density testing of Encasement materials, sponges, foam, thermal insulation materials, shoe materials, polymers and New material research laboratories.
Features
1. Suitable for sponge, foam and other types of product measurement.
2. Simple to operate and easy to use.
3. Fast measurement and Good Stability.
4. With fixed volume density measurement function.
5. Equipped with a large-capacity PC material sink.
6. Miscellaneous liquids or water may be used as the measurement medium.
7. With actual water temperature compensation function.
8. Equipped with a special windproof dust cover.
9. It 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 liquid medium (such as water), 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. Turn it on to warm up and make sure the instrument is placed horizontally.
2. According to the sample and measurement requirements, set the actual water temperature, measurement medium density and other parameters.
3. Place the sample on the measurement platform and measure its weight in the air.
4. The sample is completely immersed in the water tank containing the medium, and its weight in the water is measured.
5. The instrument automatically calculates and displays the results of density, volume, open Pore volume, closed Pore volume, closed gap rate, water absorption rate, etc.
Notice
• Please ensure that the instrument is placed smoothly and in a horizontal state before use.
• Correctly select and set the measurement medium (e.g. water or Miscellaneous liquid) and its density according to the measurement needs.
• When submerging the sample, ensure that the sample is fully immersed and the surface is free of bubbles to obtain accurate measurement results.
• Regularly calibrate the instrument to ensure Measurement accuracy.
• Keep the sink and measurement platform clean to avoid impurities affecting the measurement.
Do not use this instrument in environments with strong electromagnetic interference, violent vibration or corrosive gases.
• When the instrument is not in use, please disconnect the power supply and take good dust protection.
