ENDA-5000 Series
Stack Gas Analysis System
The ENDA-5000 Series are compact stack gas analysis systems offering continuous, simultaneous, high‑precision measurement of NOₓ, SO₂, CO, CO₂, O₂, CH₄, and N₂O using drift‑free cross‑modulated NDIR and magneto‑pneumatic detectors. Featuring an intuitive touch‑panel interface and easy‑maintenance design, they ensure reliable emissions monitoring for boilers, incinerators, and power plants.
