Quality standard

Quality is no coincidence

Rather, it is the result of a functioning system. JUMO develops and produces high-quality products for measurement, control, and automation technology. Due to an unusually high production depth for an industrial company we are able to produce quality "Made in Germany" at all levels.

3D X-ray computer tomograph

Modern technology, such as the 3D X-ray computer tomographs, ensures the excellent quality of our products.

Sense of responsibility

At JUMO, quality is the responsibility of each individual employee. Continuous process improvements can be achieved by each individual employee through our company suggestion system, an idea box, and shop floor management.


The quality of our products is particularly important to us. Comprehensive measuring and testing equipment forms the basis for this goal:

  • 3D coordinate measuring machine
  • 3D X-ray computed tomography
  • Scanning electron microscope with EDX
  • Infrared spectrometer
  • Test bench for IP protection class testing
  • Fatigue testing machine
  • GTEM cell for EMC measurements
  • and more


By systematically planning quality in advance, we develop and manufacture products that meet the quality requirements of our customers. Our quality management system is certified according to the latest DIN EN ISO 9001. Our goal is to be a faithful and reliable partner on which you can rely.

All our certificates are available for download at the bottom of the page.

Velvet gloves for herbal treatment

Dried herbs have not only become an indispensable part of the kitchen. The drying process is time-consuming. The herbs must be treated gently to guarantee optimal quality and the highest possible content of the active substance. JUMO and its partner Hofgutkräuter GmbH & Co. KG in Reinheim, Germany have developed an energy-efficient and variable solution.

Our certifications

QS ISO 9001:2015

The implementation of our process-oriented quality management system according to the requirements of ISO 9001:2015 ensures the sustainable success of our company. We aim to achieve the highest possible customer satisfaction level through continuous assessment of customer needs and expectations.


Quality assurance according to Directive 94/9/EG SEV 13 ATEX 4166 e JUMO

The implementation of the requirements for the European Directive 94/9/EG "Explosive atmospheres – application of quality systems" ensures that our devices and protection systems can be deployed in potentially explosive atmospheres when operated in line with their intended use.


Type examination certificate - SEV 13 ATEX 0197

The EU type examination certificate is valid for resistance and thermocouple temperature sensors of the type B 901xxx.x.x and B 902xxx.x.x The temperature sensors meet the requirements for explosion group II of categories 1 G and 1 D, as well as 2 G and 2 D. They are therefore suitable for use in hazardous areas of Zone 1 and 2 for gas (Gas) and Zone 21 and 22 for dust (Dust). The sensor tube may also protrude into Zone O or 20 under certain conditions (only for "Ex ia" versions or versions with a separator).


Type examination certificate - SEV 18 ATEX 0209

The EU type examination certificate is for resistance and thermocouple temperature sensors of the type 90.1xxx.xxx and 90.2xxx.xxx With the type of protection "Increased Safety", Ex "eb", the mode of operation is based on the prevention of ignition of the explosive atmosphere, which can also penetrate into the housing, by the equipment. This means that the equipment must not reach temperatures that are above the temperature class of gases that may occur at the place of use, nor may electrically or mechanically generated sparks occur. This applies both to normal operation and to foreseeable faults.


IECEx Quality Assessment Report CH/SEV/QAR13.0005/00

The IECEx Quality Assessment Report with the number CH/SEV/QAR13.0005/00 is valid for resistance thermometers and thermocouples of types B 901xxx.x.x and B 902xxx.x.x.


IECEx Certificate of Conformity SEV 13.0010

The IECEx Certificate of Conformity with the number IECEx SEV 13.0010 is valid for resistance thermometers and thermocouples of types B 901xxx.x.x and B 902xxx.x.x with protection class "ia" and "ib".


EAC Ex Certificate

Even if the GOST-R mark still appears, EAC is the valid mark based on a certificate. It is comparable to the European CE certification and confirms that products have been evaluated with regard to their technical conditions and the manufacturing or production process.
