Invasive and non-invasive modes for different patient interfaces.
Equipped with a humidity sensor and real time RH% display.
Proprietary individual expiratory heated wire control via IN/EXP ratio¹ for optimal condensation control.
Provides a high humidity output, stable performance and real-time relative humidity accuracy.
Dual servo control for chamber and patient side temperatures.
Comprehensive Operational Alarms (10+ types) – Ensuring proper and safe machine operation.
When High Patient-side Temperature alarm is activated, the device will immediately stop supplying power to heater plate and heater wire.
Safety logs can be saved and exported for traceability.
Clear LCD screen with clear settings shown on the screen.
When the system reaches stable operation, it switches to a simplified screensaver showing only the patient-side temperature for clear visibility.
Fully compatible with ISO-standard chambers and circuits—both available in reusable and disposable options.
Includes sensor cables (Temperature-humidity cable and Heater Wire Adaptor)
