Optical Oxygen Sensor, Portable

Ocean Optics Inc offers new NeoFox Sport handheld, battery-operated Optical Oxygen Sensor for measuring dissolved and gaseous oxygen pressure in a variety of media. The sensor uses a proprietary sol-gel coating that is embedded with an oxygen indicator and can be applied to patches or probes. Patches are useful for measuring headspace gases and other parameters inside packages and containers; probe options range from slender, 300 µm-diameter fibre assemblies for fine spatial resolution applications to robust, ¼-inch OD stainless steel configurations for process environments. Coating formulations are available for general lab use, high-sensitivity applications and hydrocarbon-rich sample environments. Comprised of a probe- or patch-based oxygen sensor, plus a phase fluorometer, the NeoFox Sport fluorescence-based optical oxygen system includes an onboard microprocessor with low-power OLED display, a user interface and a battery pack. The user interface permits such functions as setting single- or multi-point calibration and displaying oxygen readings in percent oxygen, partial pressure, moles per litre and other parameters. Data is captured and stored to a 2-GB SD card for retrieval on the NeoFox Sport itself or via an SD card reader connected to a PC. Response times range from <1.0 seconds in gas to ~30 seconds in liquids, with dissolved oxygen range (O2% at 1 Atmosphere) of 0-100% for most applications. Optional add-on accessories for NeoFox Sport include a battery-life extender for up to 25 hours of continuous operation and a field-friendly carrying pack with shoulder strap. OEM options are also available.
