Oxygen Analyzers
XZR200
Oxygen Analyzer
A cost effective zirconium-dioxide analyzer to measure percentage level oxygen in combustion
processes, ambient air monitoring and many more applications. The unit is configurable to
measure either 0-25% or 0-100% oxygen and offers manual or automatic calibration to suit the
customer’s needs. Two probe lengths are available (210mm & 400mm) as well as two maximum
sample temperatures (250°C & 400°C) for greater flexibility.
Highlights
• Configurable outputs: 4-20 mA and 0 to 10 V DC or
RS232 comms interface
• Cycling 3.3 V DC logic output allows direct monitoring
of the O
• Can be calibrated in normal air (20.7% O
other known O
• Selectable output filtering allows fast and dynamic or
slow and stable output
• Externally triggered automatic or manual calibration
• Diecast aluminium case IP65 with stainless steel
probe
• Sample temperature up to +400°C
