◆ Model: YL40 YL50 YL60 YL75 YL100 YL150
◆ Needle-retaining pressure gauges is composed of a general pressure gauge as the main body and a memory needle device inside.
◆ Before the instrument is used, use the button in the center of the watch window to adjust the memory needle to the zero position, when the pressure rises in use, the red memory needle will follow the movement of the pressure indicator needle and move, indicating the instantaneous pressure peak that has occurred.
◆ Instrument use conditions: the same as the original type of pressure gauge.
◆ If it is necessary to make a shockproof type pressure gauge, it can be filled with glycerin or silicone oil.
Needle-retaining pressure gauges are specially designed instruments equipped with a mechanical needle-hold (pointer stop) mechanism that locks the pointer at the maximum pressure reached during operation. This functional design makes them ideal for applications where peak pressure monitoring, shock resistance, and post-event analysis are critical.
The needle-retaining design significantly improves reliability in systems exposed to pulsation, impact, or sudden pressure spikes. It ensures accurate peak capture and reduces the chance of pointer flutter or reading errors.
