Portable Calibration Gas Instrument Generates 0.05 To 50.0ppm Chlorine in Air NIST Certified 

Want to solve stability or transportation problems with special gas mixtures in disposable cylinders? 

Then switch to the Advanced Calibration Designs (ACD) (USA) hand-held, battery operated Cal 2000 and generate, on site, a range of reactive gas mixtures in balance gas purified ambient Air. The technique is based on ISO 6145-11 Preparation of Calibration Gas Mixtures using Dynamic Volumetric Methods - Part 11 Electrochemical Generation.    

ACD CAL2000 has been sold world-wide since 1999, and is the only ATEX for EU and CSA approved for world-wide gas generation for usage in hazardous areas. It is available with interchangeable cells, standard 50 hours generating capacity and in some cases 100 hours, always with balance gas Air. Users can choose one or more generating cells from Chlorine, Chlorine Dioxide, Hydrogen Sulphide, Hydrogen Cyanide and Hydrogen. The complete generating unit weighs less than 2 Kg, is operated by  Duracell batteries, is designed to be hand-held and supplies dynamic gas mixtures on demand - no fuss, no transportation problems (as with cylinders), and unlimited shelf life. ACD and Spantech offer a back-up service which enables the CAL2000 to be re-certified every year to USA NIST standard +/-10% or +/-5% accuracy on some cases on request.
