HT-110
On-line TOC analyzer
HT-110 is an on-line total organic carbon (TOC) analyzer designed for pharmaceutical-grade water systems. It employs a continuous UV oxidation and conductivity detection method, requiring no reagents or carrier gases, and offers high repeatability (±2% F.S.) in low-concentration ranges (0–100 ppb). Built-in deaeration suppresses bubble-induced errors, while external contact input allows remote ON/OFF control. Extended UV lamp lifespan enables annual maintenance.
Why Choose HT-110
- Continuous UV oxidation conductivity method without reagents or purge gas
