Overview
The Z-105i Ein measures nitrogen oxides using chemiluminescence detection, with a modular design and microprocessor control. It reports NO, NO₂ and total NOx independently, from low ppb levels up to ppm.
Selectable measuring ranges, an ozonator with a permeable drying tank, timed dark-current compensation and adaptive signal filtering support stable readings and fast response. Large internal memory stores historical data automatically, and bidirectional RS232 allows remote control.
It is designed for atmospheric (ambient) monitoring and can also be used in continuous emission monitoring systems that use the dilution method.
