Delta F Corporation
The DF140 oxygen analyzer incorporates the company's non-depleting sensor. The units do not require frequent recalibrations and do not need rebuilt or replaced. Additionally, they have optional NEMA 4X and NEMA 7 remote sensor enclosures for installation in Class 1, Div. 1 & 2 areas. These can be installed at the sensor tap without frequent maintenance.
