Malcom Oxygen Analyzer

Malcom Oxygen Analyzer (2025 new release)

• Measurement Object: Oxygen concentrations in inert gases (non flammable and non corrosive gases that does not contain silica, liquid or vapor).
• Measurement System: Zirconia System
• Sampling Method: Pump, aspirator, or no suction device.

For the sampling gas pressure in each sampling method, refer to the sampling gas conditions.

• Pump and aspirator suction flow rate: Approx 1.0L/min
• Aspirator suction conditions: Air or N2, supply pressure 65 to 100kPaG, total discharge flow 10L/min max. (when gas inlet and outlet are at ambient atmospheric pressure).

Sample Gas Conditions

• Flow rate: 200±25 mL/min (only applies to sensor)
• Temperature: 0-50°C (non-condensing)
• Humidity:  Non-condensing
• Pressure: Pump and aspirator – 0-300 PaG; No suction device -40 kPaG max
• Measurement range: 0-10 ppm O2 to 0-100 vol% O2
• Display: 4 digit LED
• Main display: O2 concentration (auto switching)
• Sub display: Parameter or alarm/error number
• Unit: %, ppm.

Output Range

• Auto: 0-10 ppm, 0-100 ppm, 0-1000ppm, 0-1%, 0-10%, 0-100% (default)
• Other: 0-X0 ppm, 0-X00 ppm, 0-X000 ppm, 0-X%, 0-X0% can be set, X is an integer from 2 to 9
• Partial: Lower and upper value of output range can be set
