Note 1: The SO₂ enriched environments are excluded.
Note 2: In normal IAQ applications(at NTP). Accuracy is defined after minimum 3 weeks of continuous operation. The tolerance of the span calibration gas (2% unless otherwise requested)and test gas adds to the total uncertainty.
Note 3: The specifications are valid for the output load connected to ground G0. Other outputs and measurement ranges are available per request.

Note : Design and specifications are subject to change without notice.

Note : If the product has RS-485 function, to avoid damaging product, please make sure the product and the device which connect with RS-485 are on common ground.
