Maxtec MAX-250A Oxygen Sensor

I. Basic Specifications

Brand: Maxtec

Model: MAX-250A

Type: Electrochemical oxygen cell

Range: 0–100% oxygen concentration

Compatible Equipment: Mainstream ventilators and anesthesia machines; compatible with models such as Nu-Bond, Hamilton, and PB

II. Product Applications

Monitors oxygen concentration in the gas circuit in real time and outputs a stable electrical signal to the host unit, addressing issues such as oxygen concentration reading drift, oxygen sensor failure alarms, and inaccurate air-oxygen mixture concentration readings.

III. Key Features

Imported directly from the U.S., featuring stable electrode electrolyte and built-in temperature compensation; readings remain stable even in environments with condensation.

The output signal exhibits excellent linearity, ensuring precise detection across the full range. It maintains minimal light decay during prolonged continuous operation, resulting in a longer service life.

Standard threaded connector specifications allow for direct in-situ replacement. The device is quickly recognized by the host machine and requires only simple calibration after replacement.

Features a tight sealing process and resistance to moisture corrosion, making it suitable for uninterrupted, long-term operation in operating rooms and ICU equipment.

IV. Usage Recommendations

Tighten the threads during installation to ensure the gas path is sealed and free of leaks.

Perform oxygen concentration calibration after replacement.

Store at room temperature away from light; high temperatures accelerate electrolyte consumption and shorten service life.

Replace the sensor promptly if oxygen readings fluctuate frequently or if the sensor reports an error.
