Ultimate Performance

Cross-modulation non-dispersive ultraviolet absorption technology provides excellent sensitivity, stability and robustness
Continuous online measurement with fast response
Wide measurement range with up to 7 ranges selectable, minimum 0-0.1 ppm and maximum 0-10 ppm
Enhanced stability and reliability of measurement by utilizing UV LED as a light source
Enhanced Lower Detection Limit
A unique heated ozone decomposer is used as a reference gas purifier, minimizing interference and remaining unaffected by sudden changes in moisture concentration

User-Friendly Interface & Functionality

Durable 7-inch wide color touch screen LCD with intuitive interface and trend graph
Selectable metrics (ppb, μg/m³, ppm, mg/m³), response time (moving average value), and calculation method
User-configurable dilution ratio (e.g., high concentration ozone generation system)
Stream switching for measurement of two sampling points (option)

Reduced Operational Expense & Maximum Uptime

Remote diagnostics allow fast and effective maintenance
Internal parts timer with alarm facilitates timely parts replacement, optimizing parts stock
Modular design enables easy and fast replacement in the field
High-quality, long lifetime parts for maximum uptime

Connected & Intelligent

Remote operation from various devices: PC, tablet or smartphone
Modbus^TM TCP and RTU communication
USB flash drive for data storage

* Standard specification is wired LAN connection. For wireless connection, separate device is required.

Environment-Friendly Design

Utilization of UV LED instead of mercury lamp for environmental preservation and easier, timesaving disposal
Remote operation reduces emission from transportation, contributing to the reduction of carbon footprint
Long life parts reduce environmental load
