Outline：
Capable of measuring very low pressures, this gauge is most suitable to detect differential pressures caused by pressure losses in the air filter of air conditioners.
Features：
・Price reduced by mass-production for operation economy
・A highly sensitive inner mechanism with minimized friction
・Effectively withstanding pressure
・Zero position adjustable from outside
・The wall-hung version may reverse the high pressure – low pressure – connection order by changing the right and left volute joints to each other.
