MD-S220 Digital Micro Differential Pressure Gauge
Micro differential pressure sensor, designed with two sets of pressure interface micro differential pressure gauges on the back and side
Product details
The MD-S220 digital differential pressure gauge uses imported differential pressure sensors as pressure sensing components, combined with ultra-low power digital conditioning circuits, making it highly accurate and stable in the long term. The installation method is the same as that of mechanical differential pressure gauges, which facilitates on-site installation and debugging by engineering personnel.
This series of micro differential pressure gauges can be used for high-precision measurement and control of micro differential pressure in clean rooms, operating rooms, clean rooms, ventilation systems, fan testing, etc.
Product application:
◇ Pharmaceutical factory ◇ Clean room ◇ Ward and operating room ◇ Ventilation system
◇ Fan testing ◇ Purification table ◇ Air conditioning filtration system ◇ Other micro differential pressure monitoring
