The FTCM-PSt7 is a stainless steel tee with integrated microsensor. It has connectors for 1/16” steel tubing. Its inner volume of 2.1 µL is extraordinarily small, so it is ideally suited for all applications where only small volumes are available. With the tapered sensor type and its fast response time of t90 < 3 sec. in gas and < 10 sec. in liquids, real-time oxygen monitoring can be performed. The integrated PSt7 type sensor has a measurement range of 0 – 100 % oxygen, and a detection limit of 0.03 % oxygen.
