USEPA Performance Specification 11 - Particulate Monitors

The rigorous procedures for end user compliance to the USEPA PS-11 guideline standard can be very daunting - and costly! This document is available for OPAL product users to assist in planning a successful installation. Please note that there is no single particulate monitoring technology that is suitable for all applications and we strongly recommend that you consult carefully with your selected suppliers to ensure the best results.
