Institutional material:
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
Connection:
1 Black: Ground(-)
2 Red: 9-30VDC
3 Yellow: Backlight
1. The instrument comes with an alarm signal, no sensor is required to provide an additional alarm signal.
2. Using high-precision stepping motor, pointer acceleration and deceleration curve movement can be extended motor life.
3. Using high-brightness LED as backlight, high brightness and long life.
4. Accept customer's requirements to customize.
