The kit includes an Oxygen Sensor, a Torque-limiting Screwdriver, and an H1 Phillips bit—all essential for maintaining the reliability and accuracy of your analyzer. ONLY available for analyzers purchased after September 6, 2022.

Complete Annual Service:

Want peace of mind? Ensure that your VO2 Master Analyzer performs like new by sending in your analyzer (via a generated shipping label) to have a qualified VO2 Master technician perform the Annual Service through a comprehensive set of protocols: Inspection, diagnosis, humidity reconditioning, replacement of the Oxygen Sensor and Desiccant Cartridge, quality tested, and finally re-issued with a new calibration certificate.

This is the ONLY service level available for analyzers purchased prior to September 6, 2022.

NOTE: For international customers, we recommend that you check with your local customs office to find information on any potential duties that may be acquired. Any duties acquired are not included with purchase and will have to be paid separately.

Each Annual Service Kit comes with 1 oxygen sensor and 1 torque-limiting screwdriver.

Required tools: Torque-limiting screwdriver

Torque specifications for the Oxygen sensor end-plate screws: 0.2Nm
