ALP50 Bell Type Hydrogen Detector
ALP50 Main Application
This model can rapidly, within 5 minutes,complete a qualitative test on hydrogen/gas content status of AL melt before casting,therefore to decide whether the metal melt is casting ready, reducing casting waste and improving productivity. Working along with our company’s degassing & refining devices, this model can help produce high-quality casts for our customers in a fast and high-efficiency way. Despite its sole function of qualitative test, ALP50 is of an economical unit with high cost-performance ratio. It is easy to apply to testing, suitable for on-site application of casting factories. By merely examining the concave-convex surface of the tested aluminum samples, it can be decided whether casting requirements are met.
ALP50 Advantages
1.Small in size and high mobility.
2.Light in weight: approximately 27Kg.
3.Easy to use, changing process of tested samples can be observed directly.
4.Fast and convenient detecting, gas status results within 5 minutes and good repeatability.
5.Cart installation ready, more mobility.
6.Low-cost usage and maintenance.

ALP50 Hydrogen/Gas Detecting Principles
ALP50 adopts decompression solidification test methods. When tested samples solidify in vacuum, hydrogen dissolved in aluminum melt will be continuously released and forms bubbles inside or on surface of the tested samples. By detecting concave-convex level of the surface or gas hole ratio of the cross section, gas volume in aluminum melt can be determined. Test results decide whether samples are casting ready. Also hydrogen volume can be determined by examining the existence of cauliflower patterns on metal surface.
ALP50 Test Methods
1.Direct observation on the tested metal surface for concave-convex status after cooling. Concave indicates low gas volume contained and convex indicates otherwise.
2.Cut tested metal after cooling and observe the cross section for the volume of gas holes. Less holes indicate low gas contained and more holes indicates otherwise.
