Comfort-3 Scale

Therapy chair with excellent price-value rate

The Comfort-3 product line features a new underframe structure that has been developed to meet the highest expectations of design combined with ease of the cleaning. The Comfort-3 Scale chair offers continuous measurement of the patient’s weight, thus providing extra control of the dialysis process and also decreasing the administration load on the nursing staff. The weight is displayed at the chair but optionally the data can be forwarded to central data management systems. Due to the structure of the chair the scale function is less costly while providing the same accuracy.
