With more than 30 man-years of emissions monitoring and reporting experience on the design team, we can offer a scope of supply that addresses the multiple potential needs of the end user organization. A number of software and data acquisition hardware options are available. The best set of data acquisition and reporting tools to meet an end user’s needs will depend on short and long term utilization requirements, cost and performance issues. In evaluating cost, a number of factors must be considered: initial product cost, training requirements, telecommunications costs, as well as cost and availability of repairs and spare parts. In addition, utility beyond specific project requirements should be a factor.
