Overview
The Z-215i Ein is a continuous emission monitoring system for hydrogen chloride (HCl) and hydrogen fluoride (HF) in flue gas. It uses tunable diode laser absorption spectroscopy (TDLAS) with multi-reflection optics that extend the optical path for detecting low concentrations.
In-situ, high-temperature heated extraction with the analyzer installed at the sampling point avoids losses in long sample lines. With no moving parts, automatic calibration, remote operation and maintenance, and remote software upgrades, maintenance needs are low.
Key features
