Memory type pressure gauge

Pressure applied to the measurement of copper alloy corrosion of gas or liquid medium, the product has an independent measurement components, when the measured element acts, the black display pointer pressure will lead to red at the memory pointer to pressure indication, when no When the pressure into force, pressure display black pointer to zero, and the red indicator will stay in the memory location just pressure display, so that staff know exactly working pressure display value, it acts as a memory. When you need to re-record the highest When the measured pressure, turn the knob glass center table, so that the top indicator pin (red pointer) transferred back pointer (Black Hand) position to pressure display. Works memory type pressure gauge pointer with increasing measured media pressure elevated but also led to increased memory hands, when measured media pressure to reduce the pressure with the pointer drops, hands memories still remain in place maximum pressure, faithfully records the measured values ??scene occurred.
