Suitable for:Two kinds of rigid foam plastics, soft foam plastics, and foaming material research laboratory
Principle: Based on the ratio of the volume of the finished product to the volume of the raw material particles. Foaming ratio=V after foaming/V before foaming

Function:
1. Without complicated calculation, read the foaming ratio and density of foam plastics directly.
2. Having temperature compensation setting and solution compensation setting functions is more in line with on-site operation requirements.
3. One click calibration, full process peeling and weight reduction, more user-friendly operation.
4. Equipped with RS-232C interface, it can be connected to printers and computers to print test values in real-time.
5. Adopting ultra-fine suspended basket lines and large water tank design to reduce errors caused by buoyancy.
