- Based on the same core technology as the highly successful TRANSFIX, the MINITRANS is a lower cost alternative, monitoring three key gases: Hydrogen, Acetylene and Carbon Monoxide (in ppm) plus moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect a wide range of developing faults including arcing.
