TX-1100DRAP Oxygen Deficiency Monitor for Glove Box


SKU: 99021 Categories: ,


This is a specialized monitor for use in semiconductors, clean rooms, and laboratories using glove boxes or small chambers. Typically, the glove boxes are inert environments using nitrogen. The monitor can be used for low-level oxygen readings of 5% or less. Instead of trying to maintain a breathable oxygen level, the goal is to monitor a low level in a maintained environment.
