Feature

Benefit

High‑concentration capability

Proven linear output from 0 to 10,000 ppm SO2 for extreme industrial scenarios.

Excellent stability & low drift

<0.2 ppm / year zero drift and < 4% / year sensitivity drift reduce recalibration needs.

Fast response for safety applications

T90 <33 seconds ensures rapid alarm triggering in high‑risk SO2 releases

Robust environmental performance

Reliable in demanding temperature and humidity conditions, maintaining consistent sensitivity.
