Lox-O2 UV Flux Smart Oxygen Sensor – 25% O₂ Detection

Description

The LOX-O2 UV Flux 25% Oxygen Sensor (formerly known as OX-0052) is designed to be used anywhere 0-25% oxygen levels are required. This makes it a valuable safety sensor anywhere inert gases are stored or used.

The sensor benefits from lower power requirements than electrochemical and galvanic sensors, while providing a longer lifetime due to the non-depleting sensing principle.

The LOX-O2 is ppO2 and temperature compensated, enabling linear operation over a wide range without the need for additional system components. It does not contain lead or any other hazardous materials and has negligible cross sensitivity to other gases.

Features

• Internally temperature compensated, no cross sensitivity
• Direct communication to UART, no signal conditioning circuitry required
• Contains no hazardous materials; RoHS & REACH compliant
• High Accuracy; Maintenance Free

Models

• LOX-O2 Sensor – for integration into high-volume OEM products or for hobbyists.
• CM-42950 – O2 25% Smart Sensor w/ MX Board (Same functionality as the development kit without USB cable or software). 
• CM-42951 – Oxygen Smart Sensor w/ Development Kit
• Sensor Development Kit (CM-200) – Easy to use, simply plug the sensor into the PCB and plug it into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide or use our library of source code on Github to build your own application or for OEM batch testing/configuration. Order the sensor on this page, then order the Devkit here.

We recommend that all first time users purchase both this sensor and the CM-200 Development Kit for fastest and easiest results.

Case Studies

• Students use Sensor for Oxygen Mask Research

• Solid State Oxygen Sensor Benefits

• Gas Sensor Development Kit (CM-200)- designed to provide customers with an easy drop-in solution. Includes our free Gaslab data logging software. Sensor sold separately.
• Tube Cap Adapter – easily converts a wide range of gas sensors from diffusion applications to sampling. However, If you need a sampling sensor we recommend the LOX-02-F Flow Through Oxygen Sensor with tube caps instead. 
• Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.
• Nafion Tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.
• Micro Gas Sampling Pumps provide a constant flow of air across the sensor with a tube cap – perfect for bench-top testing of sensors for closed-loop sampling applications.
