SGX Sensortech(IS) Ltd Registered in England No.08067077 DS-0228, Issue 1, 14-Jul-2015 POISONING SGX sensors are designed to operate in a wide range of harsh environments and conditions. However it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments and operation. When using sensors on printed circuit boards (PCBs), degreasing agents should be used prior to the sensor being fitted.
