Dwyer Instruments 2002 Pressure Gage 321042-401 with the included 500-ohm resistorThe Dwyer 2002 Magnehelic Gage is the industry standard for monitoring differential pressure in commercial HVAC systems, cleanrooms, and air handling units. Specifically calibrated for a range of 0 2. 0" w. c., this diaphragm actuated gage provides high precision monitoring of air and compatible non combustible gases with an accuracy of 2% of full scale. The friction free Magnehelic movement utilizes a high torque magnetic linkage rather than
