Built upon Yokogawa's second generation of TDLS analyzers, the TDLS8220 continues to house all the industry's leading features in one robust device. The improved platform is designed for accurate, low maintenance, and reliable extractive oxygen measurements of process gas streams.
Features
- Analyzer, flow cell, heat trace control, insulation, purge control, and wiring termination pre-integrated
- Drop-in replacement for existing analyzer technologies
- Integrated tube-in-shell flow cell allows for tight sample heating control
- Pressure and temperature compensation included
- Advanced diagnostics with 50 days of data and spectra storage
Reliability
Reference Cell
Internal reference cell in the laser module ensures peak locking during trace measurement.
Auto gain
Auto-gain enables wide signal ranges against dynamic variation of transmission.
Validation
Validation can be initiated manually, remotely, or automatically on a daily, weekly or monthly basis defined by the user.
TruePeak
With TruePeak we can measure the area of the absorbance peak. This eliminates effects from changing background gases, allowing for simple pressure and temperature compensation.
Intuitive Touchscreen HMI
- Touch screen 7.5 inch color LCD on HMI
- Simple operation
- Provides full analzyer control and access to monitoring, historical files, and confiugrations
- Remote installation with the ability to connect up to 4 different TDLS analyzers
