InsuLogix®T sensors are tested and approved

Weidmann’s InsuLogix® T sensors have been tested and approved by Siemens Material Testing Laboratory in Nuremberg, a fully certified DAkkS laboratory operated by Siemens Gas and Power GmbH & Co. KG in Germany.

Testing Scope: Compatibility with mineral oil

The fiber optic measuring device (probe) of the InsuLogix® T has been tested for mineral oil compatibility. Each tested device was identical to the ones offered with the InsuLogix® T. They consisted of a 200 μm fiberglass cable coated in Polytetrafluoroethylene (PFTE) and a Gallium Arsenide (GAaS) sensor.

Calibration Certificate (extract)

The measuring devices are calibrated on a regular basis using the standards of the “Physicalische Teschnische Bundesanstalt (PTB) in Germany, as well as other national standards.
