The ultra-trace oxygen sensor cap UTROXCAP-SUB integrates an ultra-trace range oxygen sensor spot (without optical isolation), especially developed for underwater and deep-sea applications. The UTROXCAP can be screwed directly onto the PyroScience SUB-connector of a compatible underwater read-out device. The UTROXCAP-SUB is protected and hence highly robust against mechanical impact and ideal for long-term monitoring applications. The sensing principle is based on an optical detection method and shows virtually no drift and fast response. The UTROXCAP-SUB is especially suited for trace oxygen detection in oxygen minimum zones or during de-oxygenation events underwater.

Ultra-Trace Range. The Ultra-Trace Oxygen Sensor Cap is available for high precision deep sea measurements close to 0% oxygen. They offer about 10x higher resolution compared to standard range oxygen sensors. The specified measuring range is 0 - 44 µg/L (ppb).
Easy calibration. The sensor comes pre-calibrated and can be easily calibrated at 0% oxygen with our calibration capsule OXCAL. Simply dissolve the content of one calibration capsule in 100 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.
SUB-connector (-SUB). Underwater sensor connector (instead of standard ST-connector) needed for applications with underwater devices.
