Compensating Micro-manometer Product Introduction: The BWY type compensating micro-manometer (YJB-1500/2500 compensating micro-manometer) is structurally composed of a fine adjustment section, a level section, a reflector section, and an outer casing.
The BWY-150/250 compensating micro-manometer is used to measure the slight pressure, negative pressure, and pressure difference of non-corrosive gases. It can also be used to calibrate other pressure gauges and is suitable for use in laboratories and metrology units.

I. Core Product Applications
Multi-scenario Pressure Measurement: For non-corrosive gases, it can accurately measure slight pressure values, negative pressure levels, and pressure differences between different gases. It is suitable for monitoring gas pressure changes in laboratories and managing non-corrosive gas pressure in industrial production.
Pressure Gauge Calibration Function: As a professional calibration device, it can perform precision calibration on other types of pressure gauges, helping metrology units, testing institutions, and corporate laboratories ensure the accuracy of pressure measurement equipment, meeting the standard requirements of the metrology and testing industry.
