Analysis method

Infrared spectroscopy



Analysis range

C: 0.0001%~8% (expansible) S: 0.0001%~3% (expansible)


C: RSD ≤0.5% S: RSD ≤1.5%

Analysis time

20 s~50 s, representative value: 30 s

High frequency furnace

18 MHz, 2.5 kW

Sample mass

Iron:0.2000g Steel:0.4000g

Ambient condition

Room temperature 5°C~35°C; relative humidity ≤85%, no corrosive gas and violent vibration.

Power supply

AC220V, 50Hz, 5000W.

Oxygen gas

O2: purity ≥99.5%, pressure 0.30 Mpa, Oxygen-carrying pressure of furnace end 0.08Mpa.

Power Gas

Nitrogen or compressed air (purified); pressure imported 0.30 Mpa.

Analysis gas flow



600 mm (length)× 700 mm (width) × 860 mm (height)


  1. Discharge ash automatically using back flushing technique, it is not necessary to clean furnace end manually after thousands of analysis.
  2. Detect gas circuit by sector which is convenient to check the position leaking.
  3. Bi-carbon cell structure; wider measuring range, better linearity; select appropriate cell automatically when analyzing.
  4. Original wide-range single sample calibrating with calibrating factors: Widen calibrating curve using range and reduce calibrating frequency.
  5. Original comparison level automatic selection; wider analysis range, samples with high content or low content can be analyzed by same method.
  6. Start the analysis by “Start analysis” button without mouse or keyboard, operation is more convenient.
  7. Power:0~100% (adjustable), which is applicable to different sample.
  8. Remove adsorptions, no "saturation" of gas circuit after powering on; Both interval measuring (bath analysis) and continuous measuring (product analysis) are stable.
  9. Brevity software interface and easy operation; Statistical data (average value, range, deviation and RSD) will be out if sample is selected; Display thickness curve at real time, inquire at any time. Connect to balance without manual input.
  10. Connect with electric balance; input sample mass automatically without keyboard and mouse.
