  • Page 8: Introduction

    2.2 The company MRU GmbH Your analyzer is produced by the MRU GmbH in Neckarsulm Germany (founded in 1984), a medium sized com- pany that specializes in developing, producing and marketing high quality emission monitoring analyzers. MRU GmbH produces a wide range of instruments, from standard analyzers up to tailor made industrial analyzers.

  • Page 9: Important Information About The Users/Operation Manual

    Electrochemical sensors are by their operating principle not only sensitive to the gas they are intended for, but for other gases as well. This cross sensitivity is compensated by MRU for the typical application of flue gas analysis. However, unusual high concentration levels of single gas components might lead to a reduced measurement accuracy of other gas components and to a temporary change of the sensitivity of sensors, which may require several hours recovery time.
