Why We Use Testo
Testo instruments give us dependable, high-accuracy data that integrates directly into our reporting systems. Their wireless connectivity, field durability, and measurement consistency make them ideal for structural diagnostics, energy surveys, and building performance validation.
Other Tools in Use
Where applicable, we complement Testo with Protimeter moisture meters or FLIR thermal cameras — but for reliable temperature, IAQ, and environmental measurement, Testo remains our preferred platform.
Environmental Diagnostics That Drive Safer, Smarter Buildings
At NDTScan, we apply precise environmental monitoring to uncover hidden risks in building fabric, mechanical systems, and indoor environments. Whether supporting a construction handover, an M&E commissioning check, or a reactive maintenance investigation, our diagnostic services give clear, quantifiable data on building health and performance.
From condensation risk to ventilation efficiency, we help clients understand the real-world conditions affecting their assets. Our field teams use compact, high-accuracy instruments to gather data that feeds directly into compliance documentation, remedial action plans, or long-term asset strategies.
The Role of Environmental Data in Structural and Mechanical Safety
Most failures — be they corrosion in ductwork, condensation in wall cavities, or overheating in switchgear — start with an undetected environmental trigger. That’s why our inspections look beyond surface symptoms and dig into the surrounding conditions: temperature gradients, airflow patterns, humidity levels, and pressure variations.
For example:
-
High humidity can trigger mould growth behind cladding or plaster finishes.
-
Inadequate airflow might signal a blocked filter, undersized ductwork, or poorly commissioned HVAC.
-
Surface temperature anomalies can indicate insulation voids, thermal bridges, or water ingress.
-
Excess CO₂ levels could point to insufficient ventilation — a serious concern in offices, classrooms, and care homes.
By identifying these issues early, we help prevent more costly or dangerous failures later on.
Construction, Commissioning, and Handover Applications
Accurate diagnostics are essential during new build and fit-out projects. Before a structure is handed over, our inspections validate that heating, cooling, and ventilation systems are performing to design spec — and that insulation and building envelopes have been installed correctly.
We frequently conduct:
-
Thermal imaging surveys to assess heat retention, detect air leakage, and confirm the performance of insulation layers.
-
Air quality audits to verify occupant comfort and safety conditions, ensuring regulatory thresholds are not exceeded.
-
Humidity checks to ensure construction moisture has been effectively managed, avoiding post-occupancy condensation or decay.
These services are particularly valuable during BREEAM or WELL Building certification processes, or when local authorities demand performance validation prior to sign-off.
Ongoing Building Performance Monitoring
For occupied buildings, regular environmental diagnostics provide key insight into long-term asset health. Our team works with facilities managers, maintenance contractors, and sustainability consultants to spot issues before they escalate into breakdowns, non-compliance, or tenant dissatisfaction.
Typical issues we uncover include:
-
Overheating in plantrooms, leading to premature component failure.
-
Ventilation imbalance, which creates temperature zones or draughts.
-
Hidden damp in basements, driving slow decay or pest issues.
-
Air leakage in older buildings, pushing energy bills sky-high.
We don’t just report the problems — we give clear, prioritised recommendations that support action, not just paperwork.
Multi-Sector Expertise
Our environmental inspections are used across a broad range of sectors:
-
Education: Ensuring safe, ventilated classrooms, particularly in light of post-COVID awareness around air change rates.
-
Healthcare: Monitoring temperature and humidity in critical spaces like theatres, pharmacies, and labs where environmental control is essential.
-
Commercial Offices: Supporting workplace comfort studies and energy efficiency upgrades.
-
Residential: Investigating persistent condensation, damp, or mould in social housing or high-end developments.
-
Industrial Sites: Measuring equipment heat signatures, air flow in extraction systems, or environmental compliance in cleanrooms and workshops.
Whatever the setting, our reports are formatted for decision-makers — combining visual evidence, data logs, and practical recommendations.
Integrated Inspection Workflows
We often pair environmental diagnostics with other non-destructive tests. For instance:
-
After thermal imaging identifies cold spots, we might confirm the issue with a borescope inspection to assess insulation coverage.
-
When high humidity is recorded in a cavity, we use moisture meters to determine moisture content in the surrounding materials.
-
If abnormal pressure differences are detected in a duct system, a smoke test or airflow tracer can help visualise where the issue lies.
This layered approach means clients aren’t left guessing — they get a 360° understanding of what’s going wrong, why it’s happening, and what needs to be done about it.
Remote Reporting and Data Integration
Our field equipment connects wirelessly to central apps, allowing rapid reporting and real-time data visualisation. This means we can share findings instantly with site teams, project managers, or remote clients — enabling faster decisions, fewer delays, and more efficient remedial action.
In many cases, our inspections are linked to asset tagging or QR-based logs, so findings can be tracked over time and aligned with ongoing maintenance regimes. This is particularly useful in managed estates, datacentres, or multi-site portfolios.
Complementary Tools and Approaches
While we’ve standardised on a core platform of temperature, humidity, and pressure tools, we also use a range of other instruments when the situation demands:
-
FLIR and Seek thermal imagers for specific heat mapping needs.
-
Protimeter and Tramex moisture meters to verify suspected damp zones.
-
IAQ samplers and dust monitors for environmental or H&S investigations in industrial zones.
This flexibility means we can adapt to your specific diagnostic needs — whether that’s high-spec commissioning or reactive fault-finding on short notice.
The Value to Your Organisation
Environmental diagnostics should never be treated as box-ticking exercises. With the right tools and a focused approach, they help:
-
Reduce downtime and maintenance costs
-
Extend the life of finishes and M&E systems
-
Protect occupant health and comfort
-
Support building certification or audit processes
-
Prevent disputes over building defects or handover conditions
At NDTScan, we deliver these outcomes with speed, clarity, and technical credibility.
