OPIS 35 ATEX Certified Laser Safety Accessory

Tornado’s OPIS 35 is a high-performance, compact, lightweight, and durable laser safety accessory for the HyperFlux PRO Plus  and Process Guardian Raman analysers. Using the OPIS 35 with one of the Raman spectrometers allows the analysis to be performed safely in an explosive atmosphere. The unique design enables simple attachment to the PRO Plus allowing high accuracy measurements even at low laser power settings and ensures full compliance for an ATEX Zone 0 explosive environment.

  • Highly stable 35 mW laser maximizes quantitative measurement precision Optical and electrical signaling in accordance to IEC 60079-0, 60079-28, and 60079-11
  • Hardware interlock (24 VDC) facilitates laser shutdown trigger originating from hazardous zone
  • 24 VDC signal available for laser on/off indicator

Achieve Safety Without Sacrificing Performance

Measuring instruments certified for use in a hazardous area must be designed to operate without being able to discharge a spark. Coupled with the HyperFlux PRO Plus, the OPIS 35 provides unequaled Raman sensitivity, safety, and convenience. You get the same level of accuracy with the OPIS 35, but it is suitable for hazardous environments such as:

  • Petrochemical
  • Speciality Chemical
  • Liquefied Natural gas (LNG)


Designed and tested to meet the environmental, longevity, and robustness requirements of a hazardous environment, the laser power is controlled to stay below the 35 mW safety threshold established by the ATEX/IECEx regulations.

The OPIS 35 was designed pursuant to the set of IEC 60079 standards specifying the requirements for construction, testing and marking of equipment capable of putting optical radiation and electricity into a regulated explosive atmosphere. The OPIS 35 is certified by two regulatory bodies, ATEX and IECEx, which issue the following marks for this device:

ATEX: Ex II (1) G [Ex ia op is IIC T4 Ga]

IECEX: [Ex ia op is IIC T4 Ga]
