Model 851
HF Analyzer
Introductions
The HF gas analyzer can simultaneously measure the concentrations of HF and water vapor in atmospheric environments or industrial processes with high precision and sensitivity. The analyzer provides measurement speeds at the second level while achieving ppb-level accuracy, saving both cost and time. Installation is simple, with full setup completed in just minutes. Test results show that the analyzer is unaffected by interference from other gas species or pressure variations.
