MSA Miniox Responder
For detecting low levels of oxygen in confined spaces or in any location suspected of oxygen deficiency or enrichment. The MiniOx reading of the total percentage of oxygen detected is displayed at the push of a button. An intermittent beep warns when oxygen enrichment is detected. However when the MiniOx Responder detects insufficient oxygen levels, a high rate alarm is activated and locks out any attempt to reset the unit until it is removed to an environment where the oxygen level exceeds the warning level.
