SI-200E : O2 _ LF
SI-200E O₂ (Long Life) Explosion-proof Oxygen Detector
SI-200E O₂ (Long Life) is the SI-200E fixed detector fitted with a lead-free galvanic oxygen sensor rated for more than 5 years, so oxygen points need far fewer sensor changes than with conventional cells. Note: the lead-free sensor needs a bias voltage and takes slightly longer to stabilise at first power-up, then reads consistently in changing conditions.
