Overview
Memory sponge hardness gauge DB20-LX-MF is a DUBAN brand instrument specially used for the measurement of memory sponge Hardness. Memory sponge, also known as slow rebound sponge, space zero pressure, aerospace cotton, TEMPUR material, low rebound material, viscoelastic sponge, is widely used in high-speed aerospace, aviation and other fields.
Features
1. Using computer technology, digital filtering technology and other advanced technologies, accurate measurement of material thickness
2. Automatic indication when the battery voltage is lower than the specified value
3. Numbers are displayed, ignoring the difference
4. Utilize optional RS232C software and cables to communicate with PC computers for data collection, processing, analysis and printing functions
5. Support automatic shutdown and manual shutdown
Principle
The hardness gauge is based on the principle of press-in Hardness test, which is performed on memory sponge samples by applying a standard spring force (228gf), the Hardness value is measured, and the results are displayed digitally.
Applications
Aerospace, aviation
Standards
GB/T 531-1999、GB/T 411-80、DIN53505、ISO868、ISO7619、ASTMD2240、JIS K7215
Steps
1. Install 2 AA batteries
2. Boot ready for measurement
3. Press the hardness gauge vertically into the surface of the memory sponge sample
4. Read the Hardness value on the LCD display
5. You can choose to connect to the PC through the RS232C interface for data transmission
6. Manual shutdown or wait for automatic shutdown after use
Notice
• Operating Ambient Temperature should be kept within the range of 0~ 40 ° C (32~ 104 ° F)
• Environmental humidity should be less than 80% RH
• Measurement range should be between 10~ 90HMF
• When the battery voltage is lower than the specified value, it should be replaced in time
• Ensure that the hardness gauge is pressed vertically into the sample surface for accurate readings
