Harley Scientific Fibrecheck

Dangerous dust warning

Shortlisted for the British Safety Industry Federation (BSIF) Awards 2016, The Harley Scientific Fibrecheck 6 (HS-FC6) from SMH Products provides a real-time warning for tradespeople and others at risk of inadvertent exposure to airborne particulate.

Fibrous particles, such as asbestos, produce distinctive scatter patterns when they break a beam of light. The HS-FC6 works by drawing a constant air sample (2 l/min) through an optics module where any particles or fibres present in the air scatter the light from a laser.

This light scatter is detected by a series of photodiodes and then processed using a complex algorithm to determine whether a particle or fibre has been detected.

A ‘beep’ sounds when a fibre is detected. The unit counts the number of particles processed and then calculates the cumulative fibre concentration in terms of fibres per millilitre of air. It can display concentrations as low as 0.001 fibres/ml.

The HS-FC6 is the latest model in the Fibrecheck series; its enhanced electronics, such as the smaller pump and laser module, make it more compact and efficient, with improved fibre resolution.
