MP-500PA

MP-500PA is a series MP low-cost, compact Mini-Photohelic® differential pressure switch/gauge. It combines the time proven Minihelic® II differential pressure gauge with two SPDT switching set points. The Mini-Photohelic® switch/gauge is designed to measure and control positive, negative, or differential pressures consisting of non-combustible and non-corrosive gases. gauge reading is independent of switch operation. Switching status is visible by LED indicators located on the front and rear of the gauge. Set points are adjusted with push-buttons on the back of the unit. It is used in fume hoods, dust collection, pneumatic conveying and clean room.

• Range 0-500pa
