IRMA Gas Monitoring System
Brand: madurIRMA 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
