EMA200 - Portable, digital pressure gauge with min./max. value memory


This differential pressure gauge has a min./max. value memory and can be used for measuring positive and negative, low- to mid-range differential pressures. Flow-rate measurements are possible through the addition of a pitot tube. The EMA 200 operates by means of inductive displacement transducers that measure the deflection of the membrane of a pressure measurement capsule without making contact. Suitable for battery operation, this durable and easy-to-use instrument can be used for measuring fireplace drafts, monitoring filters, etc., thereby lending itself well to the assembly and maintenance work performed by service technicians in the heating, air-conditioning and ventilation industries. Calibration certificates from either the factory or the German Calibration Service (DKD) are available upon request.
