DYM4-1 Precision Air Box Pressure GaugeWorking Principle:
The empty box pressure gauge produced by Shanghai Longtuo Instrument is composed of an empty box group that moves axially with changes in atmospheric pressure as the sensing element. It drives the pointer through a pull rod and transmission mechanism to indicate the atmospheric pressure value at that time.
Instructions for using a precision empty box pressure gauge:
1. Please place the empty box pressure gauge horizontally when using.
2. Please lightly tap the outer shell or surface glass of the empty box pressure gauge with your fingers to eliminate friction in the transmission mechanism.
3. When observing, the pointer overlaps with the mirror pointer, and the value pointed by the pointer is the air pressure indication value, with the reading accurate to one decimal place.
4. Read the temperature reading on the empty box pressure gauge to one decimal place.
5. Empty box pressure gauge and bellows pressure gauge are professionally produced and supplied by Shanghai Longtuo Instrument. Welcome to purchase.
