• Zirconium-oxide sensor provides long service life, ppm-precision, and rapid response time for increased productivity
• Perfect for high-precision oxygen detection inside a glove box or other enclosure
• Warning： Must use the sensor at flow inert gas. Never use it under vacuum condition , which may damage the sensor

Notes & Warning
• The sensor is consumable product. (Lifespan: 6~18 months based on working environment )
• Always double check the wires installation.
• The analyzer only can measure trace oxygen during gas flowing. It cannot measure oxygen without flowing gas.
• Never allow the oxygen sensor exposed to vacuum environment
• The gas pressure measured by W3000 Trace Oxygen Analyzer can NOT be too large or too small. Working pressure range is limited from 550 to 950 Torr, pressure beyond this range is not allowed. Please use proper pressure regulator to control the pressure.
• Attention: Due to the high pressure gas output from the gas cylinder, it is necessary to install the gas pressure regulator with it to reduce the output pressure, avoid overpressurize the chamber and ensure a safe operation. Click here to learn the installation of a gas regulator.
• The use of acidic gas such as CO2 and HCl is prohibited
• If gas contain plenty of oily cent or impurity particles, please filter the gas before using
• Avoid heavy vibration to the device
• The screw cap on the sensor head needs to be removed first prior to use. And if the sensor will not be used for a long period of time, please put the screw cap back on to prevent the sensor from being damaged by prolonged exposure to oxygen.
• In order to ensure the accuracy of the measurement, the calibration frequency should be every 3 months.
