Technical features:

1) High reliability and good safety: infrared method uses characteristic spectrum to detect the concentration of sulfur dioxide. There is no chemical reaction in the analysis process after sample combustion, which improves the reliability of the instrument and reduces the failure rate. There is no need to prepare chemical reagents, which makes the work safer, and there is no need to add catalysts such as tungsten trioxide, to ensure the smooth gas path.

2) High precision and good stability: the characteristic spectrum of infrared method only has absorption effect on sulfur dioxide molecule, the test process is not affected by other gases, there is no chemical reaction, and the stability is good. At the same time, an automatic gas purging device and an air curtain are designed to ensure that they are not affected by external sulfur dioxide. In addition, the combustion temperature of the infrared method can be set to 1350 ℃, so that the sulfate sulfur which is difficult to decompose can also be decomposed. Because of the higher temperature, the test results are more stable.

3) The sample analysis weight of the infrared method is about 300 mg, while that of the coulometric method is only 50 mg. The error caused by sample non-uniformity and weighing deviation is smaller.

4) Fast test speed: the test time of one sample shall not exceed 2 minutes.

5) Simple operation: no need to prepare chemical reagent and add tungsten trioxide

6) Stable and reliable operation of the instrument: all key components adopt new design concepts and are strictly controlled to ensure stable operation of the instrument for a long time. No need for frequent calibration or calibration: the instrument can be stable for a long time after calibration, which solves the problem that similar instruments need to be recalibrated after each startup.

7) No drift in the infrared analysis room: the infrared analysis room is of modular design with a precision constant temperature system. The infrared analysis room works in a temperature environment with a uniform temperature field and a temperature fluctuation of ± 0.1 ℃. The infrared analysis room is not affected by environmental temperature changes; The infrared analysis room is equipped with shielding device, which is not subject to external signal interference. The infrared analysis room works stably without drift.

8) Precise control of gas flow: the imported automatic electronic mass flow controller is used to digitally display the gas flow, with automatic adjustment function, which can accurately and stably control the gas flow.

9) Full combustion of sample: double-layer corundum combustion tube is adopted, which has the function of secondary combustion and is conducive to full combustion of sample.

10) No internal vibration effect: the imported air pump is fixed by hanging elastic method, the instrument is not affected by the vibration of the air pump, and the noise is low.

11) Adopt a new type of automatic purging air inlet device; The airtightness test of the instrument is simple without opening the furnace cover.

12) Reserved standard interface: it is convenient to connect the LAN.
