Instrument Description: It can quickly and accurately measure the oxygen content in steel, rare earth materials, alloys, copper, zirconium, titanium, ceramics, powder materials and other inorganic materials. The instrument has the advantages of high sensitivity, good performance, wide measuring range and accurate and reliable analysis results.

1. Reliable sample extraction unit
Pulse furnace power control heating (0-8KVA), the maximum temperature can reach 3000 °C.
A variety of programming methods: constant power temperature rise, slope temperature rise.
A variety of choices of crucible design: for different sample release, in addition to the standard crucible,
2. Oxygen analysis using non-dispersive infrared detection system
3. Modular detection unit
Infrared detection unit: standard configuration Oxygen and nitrogen analyzer is equipped with two independent infrared absorption cells, which can flexibly configure the length of the absorption pool and the number of channels according to user requirements.
Detector: using German imported pyroelectric solid-state infrared CO2 detector
Motor: Swiss imported synchronous motor, continuous operation without failure
Light source: It adopts infrared light source imported from the United States, which is not easy to oxidize and has stable optical performance.
Constant temperature: The entire chamber is thermostatically controlled to ensure constant temperature of the analytical gas and ensure measurement accuracy;
Protective gas: The infrared light source and detector use nitrogen protection and purification to isolate the influence of the surrounding environment and improve stability and measurement accuracy.
Instrument parameters:
1. Analysis range
Oxygen: low oxygen: 0.0001% to 0.5% hyperoxia: 0.5% to 20%
Note: Changing the sample size can change the measurement range.
2. Analysis accuracy: 1ppm or 1%
Note: It is not more than the standard deviation or uncertainty of the sample.
3. Sensitivity: 0.01ppm
