Fisher & Paykel 900MR869 Temperature Probe

The Fisher & Paykel 900MR869 Temperature Probe is a precision respiratory accessory designed to monitor and regulate temperature and flow within heated humidification systems used in respiratory therapy. The probe connects to compatible humidifiers and breathing circuits to provide real-time feedback, enabling the system to maintain optimal humidity and temperature levels during ventilation therapy.

This probe is specifically designed for use with the Fisher & Paykel MR850 humidifier and RT-Series breathing circuits, and is also compatible with the HC550 humidifier system. By accurately measuring airway temperature and gas flow, the probe helps the humidifier automatically adjust power output to maintain consistent humidification and prevent condensation within the breathing circuit.

The device features medical-grade components and a secure connector for reliable performance in demanding clinical environments. Its design supports easy installation and integration with respiratory systems used in critical care, anaesthesia, and ventilation therapy.

Clinical Applications

The 900MR869 temperature probe is used in respiratory therapy and humidification systems to ensure stable and controlled delivery of warmed and humidified gases to patients receiving ventilatory support.

Typical clinical applications include:

Mechanical ventilation in intensive care units (ICU)

Respiratory humidification systems in hospitals

Anaesthesia breathing circuits during surgery

Non-invasive ventilation therapy

Heated humidification systems used with ventilators and oxygen therapy devices

By providing accurate temperature and flow monitoring, the probe helps clinicians maintain optimal airway humidity levels, improving patient comfort and reducing complications such as airway drying or condensation buildup in breathing circuits.
