Built-in Flow Sensor

Built-in duo flow sensors at the inhalation and exhalation ports of an anesthesia machine provide precise monitoring and control of the gas flow rates.
Help ensure that the patient receives the correct mixture of anesthetic gases and oxygen, and they also monitor the exhaled gases to ensure proper ventilation.

High Precision Vaporizer

Vaporizer can support low flow anesthesia (as low as 0.2 L/min) and high flow anesthesia (up to 15 L/min).
Accurate output of concentrations under varying conditions of pressure, flow and temperature.
Support Selectatec mounting type and cagemount compatible.
Agent type: lsoflurane, Enflurane, Halothane, Sevoflurane.
Maintenance-free.
Fill-in type: pouring.

AGSS*

Made by aluminum alloy.
High strength, light weight, never rusts.
Enhance the safety of the environment in which members of staff in closeproximity with waste anaesthetic gases and vapors (agents) work.

Other Optional Modules*

ETCO₂：
Main stream ETCO₂ module ensures continuous assessment of the patient's ventilation status, enhancing overall safety during anesthesia.
Auxiliary Oxygen meter：
Provides an additional measurement of oxygen levels, ensuring precise and continuous monitoring of the patient's oxygenation status.
Suction unit：
Used to remove secretions, fluids, or debris from the patient's airway to ensure clear breathing passages during surgery.
