Fotometrix Pty Ltd was established in 1987 by Mr. Ian Leihn as the first dedicated NATA Accredited calibration facility to specifically cater to the needs of Pharmaceutical companies, Government and other research institutions, as well as clean air testing laboratories. It remained the sole particle counter calibration laboratory for the next 23 years during which Fotometrix achieved NATA accreditation to ISO 21501-4 Determination of Particle Size Distribution - Single Particle Light Interaction Methods - Part 4: Light Scattering Airborne Particle Counter for Clean Spaces. Since its inception, Fotometrix Pty Ltd has specialised in the calibration of cleanroom testing equipment such as Airborne Particle Counters and Aerosol Photometers establishing and sustaining close customer relationships and respect. Fotometrix Pty Ltd is the sole supplier of Aerosol Photometers and Aerosol Generators designed and wholly manufactured in Sydney NSW by MicronAir Australia for the cleanroom testing industry which includes laminar flow clean workstations and biological safety cabinets. Fotometrix Pty Ltd is able to draw on many years of experience to provide an inside view of equipment currently used in this field, and also to advise beforehand of potentially costly pitfalls which may later prove to be cause for regret. should information be required prior to making a costly purchase of this type, please go to our "contact us" tab above and leave your details, and we will contact you shortly.
