1.Be suitable for all kinds of tacho RPM sensors, and display the rotation speed of the engine.
2.The gauge has the advantages of high precision, quick location confirmation and short start up time.
3.Use moving-magnet principle to drive the needle, featuring good endurance and anti-vibration.
4.IP67 waterproof and dustproof grade
5.Stepper motors used for full range of stepping gauges, great feature with its less power consumption, longer life, higher precision, etc
6.With curved glass (with anti-fogging function)
7.With ultra-wide working voltage design( long-term operating voltage: 9-32V, Maximum up to: 36V (≤ 1 min).
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.
