1. The front cover is 316 stainless steel (corrosion resistance is obviously better than 304).
2. The shell uses PBT+GF20%, the melting point is 220℃, high temperature resistance, chemical and oil resistance.
3. Curved tempered glass (strength is 3~5 times higher than ordinary glass).
4. High-transparency curved PC forms a double-layer anti-fog junction with curved glass structure, anti-fog performance is much higher than single-layer glass coated anti-fogging agent.
5. The dial is made of PC material, high temperature resistance and high elasticity coefficient.
6. Waterproof and dustproof grade IP67.
