Integral stainless steel bypass sample
system significantly increases user
productivity. The bypass valve isolates
the sensor from high oxygen levels
when changing sample lines.
Technical Specifications *
Accuracy:
< 2% of FS range under constant conditions
Analysis Ranges:
0-10, 0-100, 0-1000 PPM, 0-1%, 0-25% (CAL) FS
Auto-ranging or manual lock on a single range
Application:
Oxygen analysis in inert, helium, hydrogen, mixed and
acid (CO
2
) gas streams
Area Classification: General purpose
Calibration:
Max interval—3 months. Use certified span gas with O2
content (balance N2) approximating 80% of full scale
for fast 20-30 minute recovery to online use. Alterna-
tively, air calibrate with clean source of compressed or
ambient (20.9% O2) air on 0-25% range and allow 60
minutes on zero gas to recover to 10 ppm. For opti-
mum accuracy, calibrate one range higher than the
range of interest.
