Weidmann’s InsuLogix® H incorporates patented micro-chip based technology using nickel/palladium alloy to measure hydrogen concentration in the transformer oil. An advanced proprietary coating that protects the sensor allows it to directly contact the oil without the need for membranes or filters and enables it to measure hydrogen in both oil and gas phases.  The InsuLogix® H is also available with an optional moisture sensor (H/M) which can also be easily added later in the field.
