The XTP601 oxygen sensor is ideal for accurately monitoring the O2 levels in a reactor, and enabling the N2-purge to be shut down when the O2 level is safe. Based on thermo-paramagnetic sensor technology, the XTP601 determines the O2 level in a wide range of background gases. The sensor has a very good response time, has no consumable part, and offers “excellent” accuracy (0.02% O2 over a range of 0 to 1%), says the company. Enhancements include an integrated touch-screen display that makes configuration and calibration easier. — Michell Instruments Ltd., Southampton, U.K.
