Why Our Qualifications Matter
Accurate mould identification requires specialist training and rigorous methodology. At Scaada NZ, our analysts hold credentials recognised internationally as the benchmark for mould microscopy.
McCrone Research Institute
The McCrone Research Institute (Chicago, USA) sets the global standard for microscopy training. Their mould analysis certification program is regarded as the gold standard for fungal identification, covering advanced techniques in brightfield and phase contrast microscopy, spore morphology, and species differentiation.
AIOH Membership
The Australian Institute of Occupational Hygienists (AIOH) is the professional body for occupational hygiene in Australasia. Our MAIOH-accredited team members bring expertise in indoor environmental quality assessment, ensuring sample results are interpreted within proper health and safety contexts.
ASTM Test Methods
