What makes up a spur kit?

• A. A single pipe and filter
• B. A set of electronic sensors
• C. A battery pack and controller
• D. A manifold fitted with a number of sample pipes all terminated in foam filter assemblies

Answer: (D)

A spur kit is a multi-point sampling setup. It’s built around a central manifold that splits the airflow into several small-diameter sample pipes, with each pipe ending in a foam filter assembly. This arrangement lets you collect samples from multiple locations using one system, while the foam filters protect the sampling lines and help keep the samples clean and uncontaminated by particulates or liquids. Each branch maintains its own filtration right at the end, ensuring consistent sample quality across all points.

The other options don’t fit this purpose: a single pipe and filter can only sample one point; a set of electronic sensors or a battery/controller describes monitoring or control equipment, not multi-point sampling hardware; the foam-filtered, multi-branch design with a central manifold is the characteristic feature of a spur kit.
