1: Product Overview
The SEN-P2 digital differential pressure gauge adopts an original imported micro differential pressure sensor as the micro sensing element, combined with a low-power digital conditioning circuit, making it have the characteristics of high accuracy and good long-term stability. 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.
2: Product Features
