The safest choice

If you use a non-Ex calibrator in hazardous areas, you spend time and effort on hot work permits and using gas detectors – an intrinsically safe calibrator is an easier and safer choice.

The MC6-Ex is ATEX, IECEx, and North American-certified for use in every zone or division, so you can take it to Zone 0, 1, and 2 (Division 1 or 2).

The MC6-Ex is the safest choice for all your hazardous areas.

Ready for the field

The MC6-Ex is a multifunction process calibrator and field communicator in one device, meaning you have less to carry in the field.

Being an intrinsically safe device with excellent Ex rating, the MC6-Ex makes your life easier as you don’t need to worry about additional safety features.

The robust IP65-rated dust and waterproof casing and integrated impact protectors make the MC6-Ex ideal for use in wet and dusty environments subject to wide temperature variations.

The smart battery pack is field replaceable and can be charged inside or outside the calibrator. The MC6-Ex offers a large (5.7”) multilingual touchscreen user interface that can be easily used with bare fingers, gloved hands, or any stylus.

With the Beamex solution, thanks to automation, we have cut the number of steps needed to perform a calibration, saving 15 minutes per device. While this might not sound like much on its own, it adds up to a saving of over 4,000 hours per year.

A better way to calibrate

No other Ex-rated calibrator can outperform the MC6-Ex in terms of functionality and accuracy.

The MC6-Ex ensures accurate measurements and low calibration uncertainty in potentially explosive environments. Each MC6-Ex is calibrated in the Beamex Accredited Calibration Laboratory, making your field calibrations traceable.

It documents all your calibrations automatically, without any manual typing or use of pen and paper, and automatically performs error calculation and pass/fail analysis.

It also features an internal loop supply for transmitters, so no additional supplies are needed.

Digital data flow

The MC6-Ex is a documenting calibrator that digitally captures data at source and ensures a secure data flow between the calibrator and Beamex LOGiCAL or CMX calibration management software.

As a communicator, it even enables digital communication with smart field instruments. The seamless data flow between products delivers efficiency and high-quality data.

Use calibration management software to manage what, how, and when to calibrate, and execute the calibration with the MC6-Ex according to your pre-configured calibration procedure – even fully automatically. Maintain the full calibration history in LOGiCAL or CMX.

This solution provides accurate measurements and traceable, reliable, and reusable data that can be used for analysis, reporting and calibration certificates.

Sustainable by design

Sustainability is a core component of the Beamex design philosophy. We want you to continue using your calibrators for many years, so they are designed to have a long service life and to be as easy as possible to repair, maintain, and upgrade.

Our world-leading experts can help you to get the most out of your calibrator throughout its entire lifecycle with calibration and repair services, training, and calibration consultancy.  

To meet your changing needs, our products are constantly evolving. Firmware updates provide new features or performance improvements, and you can also upgrade your existing products with new modules or software functionalities. Accessories are quickly and easily available in the Beamex webshop.

Calibration in a hazardous area

Read the educational article and learn about calibration in hazardous areas and what you need to be aware of before entering into a hazardous area with calibration equipment.

Learn also about flammable and combustible liquids, definition of a hazardous area, the types of industries where hazardous areas are found, the different levels of hazardous zones, regulations, equipment classification and more.

User interface modes

A calibrator should have advanced functionality yet remain easy to use, which is why the MC6-Ex offers several user interface modes that are optimized for different use cases. For example, if you only want to measure something quickly and easily, use the Meter mode. If you want to perform automatic calibrations, use the Documenting Calibrator mode.

Documenting Calibrator

The Documenting Calibrator mode is designed for the documented and automated calibration of process instruments.

In today’s process plants, calibrations often have to be documented – without a documenting calibrator, this must be done manually, which takes a lot of precious time and is prone to errors.

With the Documenting Calibrator mode, the calibration process is guided, and the calibrator can automatically set the calibration points and document the results.

The Documenting Calibrator mode also works together with calibration management software.

The Calibrator mode is designed for calibrating various process instruments. It enables you to measure or simulate two signals at a time.

Often you need to check and calibrate process instruments, which typically have an input and an output. This means you either need two devices, or a single device capable of doing two things simultaneously.

The Calibrator mode is optimized for this type of use.

Data Logger

The Data Logger is designed for logging up to nine measurements simultaneously.

Often in industry, there is a need to measure signals for a certain period and to save the results for later analysis. This may be related to troubleshooting, surveillance, or calibration.

The data log results can be displayed in numerical or graphical view, and results can be transferred to a PC for further analysis.

The Data Logger mode is optimized for this type of use.

The Communicator mode is designed to communicate with fieldbus instruments.

In today’s process plants, smart instrumentation is being used to an increasing degree, so engineers need to use communicators or configuration software. Most of this instrumentation is HART, FOUNDATION Fieldbus, or Profibus PA.

The Communicator mode is optimized for communicator use to calibrate, configure, and trim your smart instruments.

The Meter mode is designed for quick and easy signal measurement.

Some multifunction calibrators are slow and difficult to use, so a simple multi-meter is used for quick measurements.

The Meter mode is optimized for simple and easy metering, meaning one calibrator can be used for all measurements.
