oxygen analyzer

GPR1500, GPR18 explosion-proofoxygen analyzerExplosion proof oxygen analyzer for petrochemical industrial processes containing hydrogen and other flammable gases. The trace oxygen and percentageoxygen analyzerInstalled inside a sturdy Exd enclosure, this oxygen analyzer is suitable for hazardous areas when equipped with a flame arrester. Electrochemical sensors that have been verified through practice have reliable oxygen sensitivity and can measure oxygen levels as low as 0-1 ppm to 0-25%.
