Shock-proof aneroid R1 blood pressure device is a complete shock-proof device that faces no damages if it even falls from a height of about 120cm. The unique features of this device include an innovative metal air channel that is patent pending & results in a steady needle deflection (both directions). It also has a high-precision valve for air release that can be twisted without resistance & is anti to wear & tear. This device has a tube connection on the crown of its pressure gauge that makes sure of unimpeded blood pressure measurements. Another advantage of this innovative shock proof R1 Sphygmomanometer is the option of pumping-up this device in lesser time as it has a completely recent ball design & integrated spoon.
