I have had a Sein Digital BP monitor for more than 10 years. It has been excellent. Model SE6000. There is a number on the machine SN:775048 and CE 0123. Cuff size for arm 23-33.
Suddenly it has malfunctioned as if there is a leak somewhere. The cuff is inflating without stopping (!) but not measuring - numbers just wildly and randomly jumping about.
Is it possible to obtain another cuff? I think the machine is still ok. Is there any service or repair arm to your company? My local medical supplier no longer carries Sein products.I am in Box Hill, Melbourne, Aust.
