**Systech Instruments' Model 913/923/933 RACE™ Cell Oxygen Analysers**

Part of the 900 Series of electrochemical oxygen analysers.

The RACE™ cell version of the 900 Series is designed for oxygen measurement where although the primary oxygen measurement is at the parts per million (ppm) level, the measuring system can be exposed to atmospheric levels of percentage (%) oxygen. This is often the case in applications involving user access to the process, such as wavesolder and reflow ovens. The RACE™ Sensor (USA and British patents pending) is a breakthrough in electrochemical technology. Our unique design prevents the sensor from being saturated by high levels of oxygen. With TURBOPURGE™, levels as low as 20 ppm can be reached from ambient air within 2 minutes. This sensor is unaffected by hydrocarbons or volatile atmospheres making it the ideal choice in many applications. This method also prolongs the life of the oxygen sensor, giving a three year minimum lifetime (warranted), with five years more typical. This instrument is available as a Bench top / panel mount unit (913 version), wall mounted unit (923 version), and a rack mounted unit (933 version).
