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
1. The instrument comes with an alarm signal, no sensor is required to provide an additional alarm signal.
