Production and development of the RRA ‘sniffer’ tubes are progressively improving.
We are proud to say that we have introduced and implemented our 4th generation tube. Some adjustments have been made to guarantee excellent quality consistency in the following areas:

• A higher contrast of colorization in case of contamination which takes away any unclear values.
• Identification of R40 in a CFK mix is highlighted with more clarity.
• Improved sampling time.
