Digital differential pressure meter LDPM-A10 is a handheld microprocessor based unit. It shows the differential pressure between indoor and outdoor, clean room and unclean room. It adopts imported differential pressure transmitter along with the advanced design of circuitry and structure. Recorded data can conveniently be stored, viewed and printed using an external printer.
