Overview

The YJB-1500 portable compensating micro pressure gauge is used for transmitting, calibrating, and testing small pressure values of non corrosive gases. It can measure the positive pressure, negative pressure, and differential pressure of small gases. It can be used as a standard to calibrate other pressure gauges and for use in laboratories and measurement units.

The YJB compensation micro pressure gauge supplied by Shanghai Longtuo consists of a fine-tuning part, a leveling part, a reflector part, and a housing part.
Compensation micro pressure gauge/YJB-1500， YJB-1500 portable compensating micro pressure gauge：
1. Fine adjustment section: The fine adjustment section is one of the main parts of the Longtuo compensation micro pressure gauge, consisting of a fine adjustment disk 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 letter 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 subjected to pressure by the dynamic pressure tube. The leveling observation part is the core part of the Longtuo compensating micro pressure gauge, and its manufacturing process directly affects the measurement accuracy of the Longtuo YJB compensating micro pressure gauge.Shanghai Longtuo Instrument Company produces YJB compensation micro pressure gaugeHaving accumulated years of experience, when purchasing YJB compensation micro pressure timing, please look for the Longtuo brand.
3. Reflective mirror part: The reflective mirror part is another main component of the Longtuo compensation micro pressure gauge, which is fixed on the mirror shell by a reflective mirror. The reflective mirror reflects the contact between the water level head and the liquid surface inside the observation cylinder, so that the tip of the leveling head is connected to the shadow tip of its reflection. The micro pressure gauge reading adjustment "base point"
4. Shell part: The long screw is supported by the shell and cross arm, and there are level bubbles and adjustment screws on the shell rod to adjust the verticality of the screw and dynamic pressure tube of the micro pressure gauge.
5. Shanghai Longtuo Instrument Company solemnly promises that customers who purchase Longtuo brand compensating micro pressure gauges can enjoy a one-year free warranty, lifelong maintenance, and technical guidance.
