IRMA Gas Monitoring System

Brand: madur

IRMA is an optical sensor for single gas detection, a successor to madIR-D - the best selling OEM solution in madur's portfolio. 

Improved construction is followed by new options and features such as implementation of MODBUS protocol and two strong "open-drain" type outputs that allows to steer external loads like pumps, valves, relays, etc. 

IRMA is ready to detect more gases than its predecessor, expanding the list of SF₆, SO₂, CF₄, C₄F₈. It can be equipped with LED display (visible from long distances).
Features
  • Available for gases: CO, CO₂, CH₄, N₂O, SO₂, SF₆, CHF₃, CF₄, C₄F₈
  • Current Analog output (0/4-20 mA) and voltage Analog output (0-5/10 V)
  • MODBUS protocol ready
  • Optional diaphragm pump
  • Optional solenoid valve for automatic ventilation and zeroing
  • Optional LED display
  • Optional aluminum chassis for sensor and its equipment
  • Two strong "open-drain" type outputs that allows to steer external loads like pumps, valves, relays, etc.
  • PC program to adjust the analyzer's settings and to view the results
