The Respirable Dust Sampler was introduced by Envirotech with technology from NEERI Nagpur in 1992. Today the company produces several models APM460, 460BL, 460NL and 460DX which form the backbone of the National Ambient Air Monitoring Programme. Over the years, feedback has been received from a large body of users on difficulties encountered in the field and possible improvements that would enhance the performance of these systems with added user friendly features. The APM 460DXNL incorporates these suggestions and provides a top of the line model for the discerning buyer who is not constrained by cost considerations and for those who will settle only for the best.
