Oxygen sensor spots allow oxygen measurements in closed sample containers with contactless read-out through a transparent window (glass, acryl glass) with special adapters and optical fibers for all types of fiber-optic meters from PyroScience. This enables incubations in closed systems, preventing potential contamination and simplifying oxygen monitoring without sampling, also in combination with pH and temperature sensor spots.
Self-adhesive technology. The spots are equipped with a self-adhesive glue on the backside of the spot for easy integration into transparent plastic or glass containers. This eliminates the use of glue and potential contamination of the spot. For information on adhesive properties, please refer to the technical note in the download tab. For measurement conditions where detachment of the spot can occur, it is advised to use the standard spots with SPGLUE.
Trace range. Trace range versions are available for high precision measurements close to 0% oxygen. They offer about 5x higher resolution compared to standard range oxygen sensors. The specified measuring range is 0-10% oxygen, with calibration at 0% oxygen and ambient air (21% oxygen), ensuring a straightforward calibration without the need of special calibration standards.
Optical isolation. For applications at high ambient light (e.g. direct sunlight, illuminated samples) and in fluorescing / light-sensitive samples, an additional optical isolation (-OI) protection layer is added to the sensor surface to reduce enhanced sensor aging and to avoid interference with the oxygen measurements
Easy calibration. A simple ambient air calibration can be performed with a few clicks (<1 minute for equilibrated setup). For precise oxygen measurements close to 0% we also offer easy-to-use calibration capsules (OXCAL). Simply dissolve the content of one calibration capsule in 50 ml distilled water, wait 10-15 minutes, perform the 0% calibration and start measurements with a calibrated sensor. For detailed calibration recommendations refer to the manual in the downloads tab.
