YJB-1500 Compensation micro pressure gaugeDetailed product description：

YJB-1500 compensating micro pressure gauge is used for measuring non corrosive gases, positive pressure, negative pressure, and differential pressure within a pressure range of less than 2500Pa. It can also be used to calibrate other pressure gauges.
Structure Overview
The compensating micro pressure gauge consists of a fine-tuning part, a leveling observation part, a reflector part, and a housing part
1. Fine adjustment part - It consists of a fine adjustment disc engraved with 200 equal parts, fixed on a long screw. When the long screw moves, the water receiver moves up or down. A gauge block is installed on the static pressure nozzle of the water receiver, which moves between the gauge plate and the character plate to indicate the displacement height of the water receiver.
2. Leveling observation section - A water level head is installed inside the observation cylinder to observe the changes in the liquid level inside the cylinder after being pressurized by the dynamic pressure tube.
3. The reflector part is fixed on the mirror shell by a reflector, which reflects the contact between the water level head inside the observation tube and the liquid surface, so that the tip of the water level head is in contact with the shadow tip of its reflection, indicating the adjustment of the micro pressure gauge reading "base point"
4. Shell part - supported by the shell and crossbeam, the long screw is equipped with a leveling bubble and adjusting screw on the shell to adjust the verticality of the screw and dynamic pressure tube of the micro pressure gauge.
