A couple of months back I also had the same question. I was also confused about which digital blood pressure machine to buy for its accuracy and reliability in India. I was buying it for my grandmother who is suffering from high blood pressure. Actually, the issue was we were unable to find that her’s blood pressure is high. since the hospital was far we were in need to buy a digital blood pressure device at home so if in case we find something wrong we can just use the device & check blood pressure. One of my friends suggested to me Arkray Healthcare.
