As aforementioned, the calibration will cover five parameters to give you a better understanding of your particle counter: size setting error, counting efficiency, sampling flow rate error, size resolution, and false count. The uncertainty of each particle size will be stated in microns. This metric will be determined by comparing a particle to a National Institute of Standards and Technology NIST traceable particle with higher sensitivity.
The uncertainty is stated in percent counting efficiency. The flow value uncertainty is stated in liters per minute LPM. The uncertainty will be stated in percent size resolution. This is also known as the zero-count test. We also state the false count rate in accordance with JIS B , which gives a limit of one count per five minutes.
Both values are stated as average observed counts in five minutes. It is simply a measurement of the doubt that exists about the results of any measurement.
All stated uncertainties are traceable and rely on the accuracy and specifications of our test equipment and reference particles. We use sound formulas for calculating uncertainty for the 5 calibration parameters. Lighthouse Worldwide Solutions is dedicated to setting best practices in the industry for testing, calibration, and particle counting technology.
While uncertainty is statistically impossible to avoid, we do everything we can to keep it low and honestly reported with accurate tracing. This is the easy one! This set of guidelines holds unique possibilities not available through other certifications. Lighthouse is very excited by the possibilities ISO calibration allows for customers across the entire world.
ISO is a set of guidelines set forth by the International Standards of Organization, an independent organization dedicated to setting standards of practice across the world. The IEC is an international organization designed to set standards specifically for the electrical, electronic, and technology industries.
Together, these two organizations have created high standards that will allow laboratories to ensure the quality, reliability, and repeatability of performed tests or calibrations. The calibration covers size setting error, counting efficiency, sampling flow rate error, size resolution, and false count in the actual equipment.
The guidelines also cover:. Well, also, as manufacturers, LWS want to make sure it provides the absolute best technology has to offer so you can feel secure in your particle counter data integrity and data quality. You can rest assured that your product has been built in a lab that has gone through rigorous testing, as well as regular internal audits and external certifications.
Part of this process is being regularly evaluated by independent third-party certification bodies, such as A2LA. This keeps best practices at the forefront of our minds. So you can know that you are securing the best for your business in a long-term investment, and rest assured you have the best in the industry.
Working with a lab that is accredited for ISO is another way for you to be sure that you are receiving the best technology has to offer.
