Eliminate the need for cylinders of reactive gases with on-demand generation, to NIST standards, at a fraction of the cost of bottled gas, no shelf life and no transport issues, take it with you wherever you go, up to 8 gases in a single case. Portable and simple to use, the future of reactive, toxic gas calibration, from ppb to high ppm levels.
Historically, calibration gas came in the form of cylinders, which have severe limitations. Cylinders of cal gas are most often filled almost entirely with air, which makes them extremely inefficient. 99.999% of a 10 PPM cylinder of any gas is simply clean dry air. ACD uses the background air at the calibration point to blend with the desired gas which provides enormous advantages.
ACD products generate the gas on demand rather than storing it, providing many advantages over the old approaches. Since there is no gas present until the user requests it, and the gas is never under pressure. ACD products are safe for air transport and do not deteriorate over time. It is not uncommon for customers to use the same calibration source for 5, 10 or even 15 years of calibration.
The on-demand generation of the gas allows a single calibration source to generate adjustable concentrations. Cylinders are a single fixed concentration. Most ACD generating sources can provide concentrations of between 0.25 and 125 parts per million. In addition to this, the flow rate can be varied between 0.2 and 1.0 liters per minute using the internal pump. Calibrations of sample drawing gas detectors can be accommodated by the use of the internal mass flow sensor.
ACD products are designs that continue to evolve and expand for the future needs of the industry. At ACD, we continue to add new gases to our existing line of instruments. As these sources become available, they will be integrated into use with the instruments you already have. Our goal is to provide gases for any manufacturer’s instruments at any flow requirement or concentration required by the end-user at the point of calibration.
