Double Needle Pressure Gauge
- Oct 29, 2018 -

The so - called two - needle pressure gauges refer to two - needle and two - tube pressure gauges, is a more typical special pressure gauges. The instrument is provided with two object interfaces, which can access two objects simultaneously, and the pressure of each object is indicated by the color separation pointer at the same time. It is especially suitable for two measuring objects that require simultaneous reading alignment. The internal structure of the double-needle pressure gauge is also very characteristic. It combines the two measuring mechanisms organically and independently. The two independent measuring mechanisms drag their own Pointers to indicate their pressure on the same dial. The comparison error is reduced to the maximum extent from the indicator device and the precision of the comparison reading is improved obviously.
