The present disclosure provides a measurement system comprising a measurement application device comprising a measurement data acquisition interface configured to acquire measurement data, a data storage, and a cryptographic data encoder communicatively coupled to the measurement data acquisition interface and the data storage, wherein the cryptographic data encoder is configured to cryptographically encode the acquired measurement data and to store the cryptographically encoded measurement data in the data storage, the measurement system further comprising a user interface comprising a measurement data interface configured to retrieve the cryptographically encoded measurement data from the data storage, a cryptographic data decoder coupled to the measurement data interface and configured to cryptographically decode the retrieved cryptographically encoded measurement data, and a user interaction unit configured to provide the user with means for interacting with the cryptographically decoded measurement data. The disclosure further relates to a method, and a respective measurement application device.

In at least one embodiment, a mobile measurement system includes a handheld device, a measurement device, and an optical sensing device. The measurement device and the optical sensing device are communicatively coupled to the handheld device. The handheld device receives measurement data that comprises at least one measured electrical parameter corresponding to a physical property of an external system. The measurement device generates measurement data that corresponds to a period of time. The measurement device communicates the generated measurement data to the handheld device. The optical sensing device generates optical data corresponding to an interface of the measurement device and the external system where the measurement data is being generated. The generated optical data corresponds to a particular time within the measurement period of time. The mobile measurement system associates and stores the generated optical data for the particular time with measurement data corresponding to the period of time.

The invention relates to a pressure gauge comprising a dial comprising a marking and a pressure indicator configured to rotate with respect to the dial, the pressure indicator changing orientation and/or position relative to the markings as it rotates. The marking comprises a two-dimensional code that encodes at least one given information item. The pressure gauge comprises a graphic reference acting as a reference position so that the pressure indicator can be positioned in space. The invention also relates to a valve unit for distributing fluid, particularly gas, comprising such a pressure gauge and an assembly for distributing fluid, particularly gas, comprising a gas container, such as a gas cylinder, to which such a fluid distribution valve unit equipped with such a pressure gauge is fixed. Another aspect of the invention also relates to a method for measuring the pressure displayed by a pressure gauge.
