NNDAQ

State-of-the-Art Solution for Reliable and Accurate Flow Measurements in Transport Ducts or Stacks

The Non-Nulling Data Acquisition™ (NNDAQ™) system measures the flow rate of a gas in transport ducts or stacks. This system comes in automated and manual versions and allows for measurement with up to 4 probes simultaneously. The system offers the ease of EPA Method 2 and the accuracy of EPA Method 2F by using a non-nulling algorithm developed by NIST to perform reliable, efficient, and accurate flow measurements.
