EKM Inflation Device is a one-piece, plastic, 20cc disposable inflation device with a lock lever design that controls the piston, a manometer, and a connecting tube with a male rotating adapter. The manometer measures pressures ranging from vacuum to 30atm; the gauge is marked in 1atm increments. The gauge also has an inner scale of comparable PSI measurements. The accuracy of the manometer has been determined to be within 1atm over the range.
