Managing Director

Christabel established Portable Spectral Services back in 2011 with the aim of furthering the use of handheld XRF within the mining industry. From small beginnings, Chris has grown the company from a simple portable XRF hire company to one that encompasses all kinds of spectral technology and service offerings.
