Bretby Gammatech Ltd.
is a pioneer of natural gamma radiation for the monitoring of the ash content of coal. 

Our customers include all the major coal producing markets across the world, including China, US, India, EU, Indonesia, Colombia, Mongolia, Russia, Africa and Kazakhstan, where we supply our innovative ash monitoring equipment to mines, coal processing plants and ports.

We have over 20 years’ experience in designing and developing coal monitoring technology that enables our customers to quickly and easily monitor the quality of their coal, with 99 per cent accuracy. 

The equipment we sell improves the quality of coal.  This is vitally important as lesser quality coal – with a high ash content – could be rejected by the end customer, at huge cost to the producer.   Our products are accurate to within one per cent of actual laboratory analysis and therefore enable the customer to carry out real time decision making.   

Our world renowned products include the Ash Probe, Lab Ash, Ash Eye, Heat Eye and Gamma Eye.
