Working live around switchboards, condensing units and control circuits means your electrical testing tools have to be accurate, rugged and compliant – no exceptions. Our Electrical Testing range brings together clamp meters, digital multimeters, voltage testers, megohm meters and test leads from trusted brands like Testo and Fieldpiece, purpose-built for HVAC and refrigeration work in Australian conditions.

This page is all about electrical test equipment – not electrical contracting services. Always use a licensed electrician for any installation or fault finding on fixed wiring and switchboards. These instruments help you test safely and efficiently on the job

Why Quality Electrical Testing Tools Matter in HVAC

From no-cool callouts to nuisance tripping, modern HVAC work is as much about verifying power, current draw and insulation resistance as it is about refrigerant and airflow. The right electrical tester helps you:

Confirm power supply and phase presence before you touch equipment.
Diagnose motors, compressors and contactors quickly and confidently.
Check microamps, capacitance and continuity for control and safety circuits.
Prove equipment isolation to support your lock-out/tag-out procedure.

In many workplaces, regular inspection and testing of electrical tools and extension leads is part of WHS duties. Your test instruments need to be up to the job, day in, day out.

Electrical Testing Tools You’ll Find in This Collection

Clamp Meters for Live Current Testing

Clamp meters let you safely measure current without breaking the circuit – ideal for checking compressor, fan and pump loads. This collection includes options like the Testo 770-3 Clamp Meter , designed for tight switchboards and HVAC applications with features such as True RMS, inrush current measurement and intelligent jaw design.

Digital Multimeters for Everyday Diagnostics

For day-to-day service work, a reliable multimeter is non-negotiable. We stock high-quality meters such as the Testo 760 series digital multimeters and the Fieldpiece HS36 True RMS expandable multimeter kit , built for HVAC technicians who need voltage, current, resistance, microamps and temperature in one rugged instrument.

If you’re building out a full toolkit of meters, you can also explore our dedicated Multimeters collection for more options tailored to different budgets and feature sets.

Voltage & Continuity Testers for Fast Safety Checks

Non-contact and two-pole voltage testers help you quickly verify presence or absence of voltage before you proceed with work. Popular options such as the Testo 745 Non-contact Voltage Tester offer visual and audible indication, adjustable sensitivity and IP67 protection – a great fit for damp plant rooms and outdoor units.

You’ll also find current/voltage testers and classic two-pole testers for technicians who prefer a direct-contact verification method.

Insulation & Megohm Testers

Insulation resistance testing is critical when assessing motors, compressors and cabling for moisture ingress or breakdown. Our range includes digital megohm meters such as the Fieldpiece SMG5 Digital Megohm Meter and related accessories to help you pick up insulation issues before they become costly failures.

Leads, Probes & Electrical Test Accessories

A tester is only as good as its leads and probes. This category includes silicone leads, alligator clips, replacement tips and accessory kits – for example, the Fieldpiece Deluxe Lead Kit for Multimeters (ADK7) – so you can replace worn parts, upgrade to more flexible leads, or build task-specific test setups.

For an even wider range of measurement tools, you can browse our Test & Measurement collection, covering everything from digital scales and vacuum gauges to thermal cameras.

How to Choose the Right Electrical Tester for Your Job

Not sure which electrical testing tool is right for you? Use these practical checks to narrow it down:

Application: Are you mostly checking compressor current, doing general service, or carrying out fault finding on controls and safety circuits? Clamp meters shine for current; multimeters are ideal for all-round diagnostics.
Electrical range: Confirm the voltage and current range covers your typical work – for example 230 V single phase, 400–415 V three phase and common control voltages.
True RMS & accuracy: For VFD-driven motors and non-linear loads, a True RMS instrument will give more reliable readings than average-responding meters.
Safety category & IP rating: Look for the appropriate CAT rating (e.g. CAT III for many distribution boards) and ingress protection suited to plant rooms or outdoor work.
Build quality & ergonomics: A good tester should be easy to read in poor light, comfortable in one hand and rugged enough for site work.

Safety, Standards & Compliance

Electrical work is hazardous and should only be carried out by appropriately licensed or registered electricians. Always follow your local WHS procedures, lock-out/tag-out requirements and the manufacturer’s instructions for each instrument.

In many workplaces, portable electrical equipment (including power tools and leads) must be inspected and tested at intervals that reflect the operating environment, typically in line with Australian Standards such as AS/NZS 3760 and relevant WHS regulations. Use your electrical testers as part of a broader safety system, not as a substitute for safe work practices.

Electrical Testing – Frequently Asked Questions

What electrical testing tools do HVAC technicians commonly use?

Most HVAC technicians carry at least a clamp meter, a digital multimeter, a non-contact voltage tester and a basic continuity tester. Many also use a megohm meter for insulation testing on motors and compressors, along with a selection of high-quality leads and alligator clips for safe connections.

Are your electrical testing tools suitable for use in Australia?

Yes – the electrical testers we stock are sourced from reputable manufacturers and are designed for use on Australian mains voltages and frequencies. Always check the product specifications, safety category rating (CAT) and compliance markings on the individual product page, and ensure you follow local regulations and licensing requirements.

Can I use these tools on live circuits?

Many clamp meters, multimeters and voltage testers in this collection are designed for live testing, provided they are used in accordance with the manufacturer’s instructions and within their rated category. However, live work should only be undertaken by qualified and licensed persons following appropriate risk assessments, PPE requirements and isolation procedures.

Do your meters come with calibration certificates?

Some instruments include a factory calibration certificate, while others are supplied calibrated to the manufacturer’s internal standards. Check the “What’s included” or specifications section of each product listing, or contact us if you need a specific level of documentation or ongoing calibration support.

How quickly can you deliver electrical testing tools?

We ship Australia-wide using reputable couriers, with dispatch and delivery times dependent on stock availability and your location. Capital cities typically see faster delivery than remote and regional areas. Full details are available on our Shipping & Returns page.

Can I get help choosing between two meters?

Absolutely. If you’re weighing up two clamp meters or multimeters, reach out via our Contact Us page or submit an enquiry through our HVAC Tool Quote form with the models you’re comparing. We’re happy to talk you through the differences in range, features and suitability for your work.
