Expert Selection Guide & FAQ

• How do I identify when the MIDAS-S2-I-COS cartridge requires replacement?
• The MIDAS S2 transmitter will display a "Sensor Expired" fault code; plan for a 5-year replacement cycle.
• Does this sensor require a specific flow rate to maintain 0-20 ppm accuracy?
• Yes, the unit relies on the internal pump of the transmitter; ensure sampling lines are unobstructed.
• What is the best practice for calibrating the COS sensor?
• Use a certified 10 ppm COS calibration gas and perform a zero-point check in clean air first.
• Can the MIDAS-S2-I-COS be used in sub-zero environments?
• The operating range starts at 15°C; temperatures below this may lead to sluggish response times.
• Why is Carbonyl Sulfide (COS) detection more difficult than H2S?
• COS is more stable and requires the specialized sensor tech found in the MIDAS-S2-I-COS for precision.
