Shop genuine Testo HVAC instruments in Australia for refrigeration service, air-conditioning commissioning, thermal diagnostics, IAQ checks and electrical verification. This collection brings together Testo digital manifolds, Smart Probes, thermal imagers, hygrometers, airflow instruments and electrical testers so tradies can build a measurement kit that works properly on real jobs.

Whether you are checking superheat and subcooling on a split system, verifying airflow on an AHU, tracking humidity in a problem room or using thermal imaging to spot faults before they become call-backs, Testo gear is built for accurate readings and cleaner app-based workflows. For cross-brand wireless tools, also browse our Bluetooth Smart Tools range. For broader instrumentation, see Test & Measurements.

How to choose the right Testo tool

• For charging and commissioning: choose a digital manifold with the refrigerant support, port sizes and app functions your team actually uses day to day.
• For lightweight service work: Smart Probes are a strong fit when you want portable pressure and temperature measurement without dragging a full manifold body everywhere.
• For evacuation proofing: pair compatible gear with a dedicated vacuum gauge and check your workflow suits the systems you service most.
• For charging accuracy: add a refrigerant scale so your measurements translate into repeatable charging practice.
• For thermal and building diagnostics: choose a thermal imager when you need to see insulation defects, hot electrical components, moisture risks or temperature imbalance.
• For airflow and IAQ: choose anemometers, hygrometers and IAQ tools when the job is comfort, balancing, mould risk or verification work rather than refrigerant-side service.

Popular Testo categories at HVAC Shop

Digital manifolds and refrigerant diagnostics

Testo digital manifolds suit tradies who want faster pressure, temperature, superheat and subcooling workflows with app-based reporting. Browse related refrigerant gauges for manifold-style tools and accessories.

Smart Probes and Bluetooth tools

Testo Smart Probes are ideal when you want compact wireless diagnostics for AC and refrigeration work. They are especially handy for service work, commissioning checks and quick measurement capture using the Testo Smart App.

Thermal imaging

Testo thermal cameras are useful for HVAC fault-finding, electrical hot-spot checks, building envelope diagnostics and general maintenance inspections where seeing the problem early saves time on site.

IAQ, humidity and airflow instruments

For comfort checks, balancing and mould-risk investigations, Testo also covers hygrometers, anemometers and indoor air quality meters.

Electrical testing

For HVAC electricians and service techs working around switchboards and controls, Testo electrical testing instruments help verify voltage and related checks with trade-focused simplicity.

Frequently asked questions

Are these genuine Testo instruments?

Yes. HVAC Shop states that it supplies genuine Testo instruments sourced through authorised Australian channels.

Do Testo manifolds and Smart Probes work with the same app?

Many Testo manifolds and Smart Probes work with the Testo Smart App, which makes it easier to view measurements, log results and export reports.

Do Testo digital manifolds support modern refrigerants like R32?

Many current Testo manifold platforms support common refrigerants used in Australia, but tradies should always confirm the specific refrigerant list on the product page or datasheet before use.

Do I need a licence to use these tools?

You can buy and own the instruments without a refrigerant licence, but any work that involves handling scheduled refrigerants in Australia must be carried out by appropriately licensed people and authorised businesses where required.

What should I buy with a Testo manifold?

Common add-ons include a vacuum gauge, a refrigerant scale, and supporting tools from the refrigerant gauges range.

Which Testo option suits lighter service work?

For many service technicians, Smart Probes are the lighter and more portable option when full manifold workflows are not needed on every job.
