  • Page 6: Introduction

    ISM-3 can via a simple menu structure be programmed to give alarm in case of a too high or too low O concentration. Besides that alarm is given in case of insufficient flow of measuring gas, or in case of other faults in the ISM-3.
  • Page 7 • Supplied as stand-alone or for incorporation. ISM-3 is specifically built for measuring on clean dry gases and gas mixtures where a great measuring precision, reliability and long term stability and alarm control of flow and content of oxygen are required.
