Oxygen analyser OZR 8000

industrialconcentrationtrace

OZR 8000 Trace Oxygen Analyser meets the requirements of industrial gas production and thermal treatment industries. Measuring principle –The oxygen in the sample gas diffuses from the sample side of the ZrO2 cell through to the outside (ambient), thereby a potential gradient exists which is measured via the inner/outer electrodes. –The change in the potential gradient is proportional to the change in concentration of oxygen present in the sample gas –The reference value is always ambient air. Measurement method - Zirconium dioxide detector Ranges - Factory preset 0 – 1/10ppm Freely configurable up to 250 000 ppm Analog Output signals - 2 x 4..20mA configurable Digital output - Ethernet-10/100BASE-T (standard) 4 x D/O configurable (standard) Modbus RS232/485 Profibus DP/PA and Profinet (optional) Linearity - With such measuring principle, Zirconium Dioxide cells are base linear. Repeatability - < 1 % of the measurement range or 100 ppb O2 (whichever is greater) Zero Drift - < 1 % of the measurement range per week or 250 ppb O2 (whichever is greater) Sensitivity Drift - <1 % of measurement range per week or 250 ppb (whichever is greater) for pure samples. Output Fluctuation (2 σ) - < ± 0.5 % of the measured value or 50 ppb O2 (whichever is greater) Detection Limit (4 σ) - < ± 1 % of the measured value or 100 ppb O2 (whichever is greater) Warm-up time - < 15 minutes Response time - T90 < 60 sec at a sample gas flow of 8 l/h and electronic T90 time (static/dynamic) = 3 /0 sec Sample gas T° - +5 to 45°C Pressure - ≤ 70 hPa, outlet pressure: atmospheric Flow rate - 4 – 20 L/h Connections - 3mm Swagelok ® (inlets) 1/8 NPT internal thread (outlets)
