With unique ultra-low drift infrared cell, Sundy SDS212 only needs to be calibrated once every workday, and then it can work continuously, China National Coal Quality Testing Center certified. The performance is more stable, and the test efficiency is higher.

Gas is supplied by sample introducing rod which is hollowly designed. And the software could decide whether to supply gas or not according to the position of the sample introducing rod. As a result, the oxygen consumption decreases by 20% The sample introducing rod has a self-protection function. Once the sample is introduced, the rod extracts itself from the hot zone thus prolonging its working life.
