DF140 Oxygen Analyzers do not require frequent recalibrations and never have to be rebuilt or replaced. They arrive fully calibrated to NIST standards and are ready to use out of the carton. 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 worry of frequent maintenance.
