Technical Characteristics:
Imported micro differential pressure sensor with high accuracy and good stability
Multiple pressure units switching
High / low pressure alarm, sound / light alarm can be set
Multiple function: switch on / off, clear, peak record, sound and light alarm
Powered by 2 AA batteries, which lasts more than 12 months
The MD-S220 series differential pressure gauge adopts the original imported differential pressure sensor as the pressure-sensing element, combined with the ultra-low power digital conditioning circuit, which has the characteristics of high accuracy and long-term stability. The installation method is the same as the mechanical differential pressure gauge, which is convenient for engineers to install and debug on site.
This series of differential pressure gauges can be used for measurement and control of high-precision differential pressure in clean rooms, operation rooms, clean rooms, ventilation systems, and fan testing.
