Leak Detectors

OpTech-O2 Model P

This oxygen analyzer separates the sensor from the analyzer to allow many unique applications.  The sensor can be placed inside transparent or translucent packages so that headspace oxygen can be measured in packages non-invasively.  

The sensor can be mounted permanently through a package using our ImPULSE sensor accessory, so that oxygen levels can be measured on the same package, day-after-day, without any consumption of the headspace gas – perfect for shelf-life studies!  The sensor is made up of a proprietary dye, so it can be incorporated into packaging for non-invasive, on-line headspace gas analysis.  The applications are endless!
