Product Description

5 Tube Pneumatic AHD

Anaesthetic rotameters are used for measuring the rate of flow of gases used for anaesthesia. The gases measured are oxygen, nitrous oxide and air.

Special coated tubes are also available where the tubes are treated both inside & outside with antistatic coating for easy dissipation of static charge. The back panel is made of fluorescent material for easy visibility in low light condition. The tubes conform to the relevant international standard for safety.

The Flowmeters are equipped with flow control knobs. These knobs are color-coded and also touch coded in conformity with international standard for easy identification. The oxygen knob has a distinctive profile as required. Other knobs are serrated, round and smaller than oxygen knob in diameter.

Anaesthetic rotameters with anti-hypoxia system can be of 3-tube, 5-tube or 6-tube design. In 3-tube design, there is no low-flow tube provided. In 5-tube design, only oxygen and nitrous oxide have low-flow tubes; air is not provided with low-flow tube.

The anti-hypoxia system ensures that a minimum of 25% Oxygen always flows in the mixed gas output so as to ensure patient safety.
