built for accurate diagnostics, commissioning and maintenance work. This range suits HVAC/R technicians and trade buyers who want reliable readings on-site — from temperature and pressure through to airflow, IAQ and thermal checks.

Quick ways to shop Testo

• Thermometers & Probes (clamps, penetration, surface, NTC sensors)
• All Brands (compare with other trade favourites)

What to choose (fast trade guide)

• Service & diagnostics: start with smart probes or a kit that covers temperature + pressure for quicker call-outs.
• Commissioning & balancing: look at airflow tools (anemometers/hoods) to verify performance, not guess it.
• IAQ jobs: CO₂ / humidity tools help document indoor conditions for clients and facility managers.
• Reporting & compliance workflows: choose models that support logging/export so you can attach readings to job notes.

Trade notes

• Calibration & traceability: if you need documented accuracy for QA or facilities work, plan a calibration schedule to match your site requirements.
• Refrigerant work: measurement tools support diagnosis, but refrigerant handling must be completed by appropriately licensed technicians.
