Modus Instruments introduces the Model MA2 hand-held digital manometer designed for HVAC test and balance work, furnace draft measurement, cleanroom, or paint spray booth differential pressure measurement and other specialized low differential pressure measurement applications. Its sensing element is a differential capac itance cell designed to operate at extremely low pressures. Differential pressure ranges from 0.1- to 10-in. water column (25 PA to 2.5 KPA) are standard.
The MA2 operates on one 9-volt battery (140-hour minimum). Accuracy is ۫ percent of range plus 1 digit; position sensitivity is less than 2.5 percent of range. Operating medium is air or non-corrosive, non-explosive gases.
