Why this principle
SPXCDXS*SS cartridges are pre-calibrated and plug-and-play: the transmitter auto-recognizes the cartridge, hot-swap replacement needs no special tools. When a sensor reaches end of life you replace only the cartridge — not the whole instrument — cutting spares cost and downtime. One transmitter accepts catalytic, electrochemical (SureCell) and IR cartridges.

Installation
Replacement: power down (or confirm the area is safe), unscrew the old cartridge, plug in the new one — gas type and range are recognized automatically. Then run zero and span calibration from the magnetic-wand menu. Recommended cal gas: clean air (20.9%Vol) for O2; 25 ppm H2S; 100 ppm CO; 500 ppm H2; 5 ppm NO2; 50%LEL for flammables; 1%Vol for CO2. EC cartridges work at -20 ~ +55 °C, IR at -20 ~ +50 °C.
Calibration notes & sensor life
Warm up 30 minutes before calibration. Zero gas (air/N2) 0.5–1.0 L/min, flammable span 1–1.5 L/min, O2/H2S/CO/H2 0.5–1.0 L/min. H2S zero must use compressed air with 20.9%Vol O2 (never nitrogen) — flush 3 min, then span gas 2 min. Oxygen needs no zero. Typical life: catalytic ≈36 months (poison-sensitive), O2/toxic 24+ months, NDIR longest (immune to poisons). Accuracy degrades in oxygen-deficient atmospheres (O2 <6%v/v).
