Vacuum and Smoke Testing

HTC provides a full range of vacuum and smoke testing equipment for hire, purpose-built for identifying leaks, cracks, and structural issues in manholes, pipelines, and underground infrastructure. These tools help confirm system integrity, detect points of infiltration, and assess the presence of harmful gases, fumes, or contaminants in confined spaces.

Designed for reliability on New Zealand worksites, our range includes vacuum test pumps, test head bladders, and high-output smoke generators — delivering fast, accurate diagnostics for councils, contractors, and civil maintenance teams. Whether you’re verifying new installations or assessing existing networks, HTC’s testing solutions support safer, more compliant, and more efficient operations.
