big ben® aneroid BP set, square, desk

The Riester big ben is an aneroid (mercury-free) blood pressure gauge with a large, square, easy-to-read dial. This is the desk model, with an adult velcro cuff.

A microfilter protects the air-release valve and the measuring system, the valve allows fine adjustment, and the chrome-plated screw connection lets cuffs be changed quickly. Accuracy is ±3 mmHg. The big ben is approved by the British and Irish Hypertension Society.
