Voltage, Phase & Process Meters

82 products

Working safely and accurately around electrical and process systems starts with the right meter in your hand. Our voltage, phase and process meters give Australian electricians, technicians and instrument specialists dependable readings for testing, commissioning and troubleshooting, whether you are confirming a supply, checking rotation or calibrating a loop. 

The range answers several distinct needs. Voltage testers and indicators confirm presence and level safely before work begins, phase rotation testers verify correct sequence on three-phase supplies to protect motors and drives, and process meters and loop calibrators source, read and simulate the 4 to 20mA and voltage signals that instrumentation runs on. 

Picking the right tool depends on the task, the environment and the safety category you need. Our team can help you choose an instrument that suits the work and keeps you protected around live systems. 

Reliable results and safe work both depend on a meter you can trust, and accuracy fades without checks. We calibrate the test instruments we sell, backed by ISO 9001 certified processes and traceable results that satisfy compliance and audit needs. 

We deliver to electricians, plants and instrument technicians across Australia. Need help matching a meter to your work? Get in touch and we will point you the right way.

Frequently Asked Questions

A phase rotation tester confirms the sequence of the three phases on a supply, showing whether rotation is clockwise or anticlockwise. Correct sequence matters because connecting a three-phase motor the wrong way runs it in reverse, which can damage equipment or a process. The tester prevents that costly mistake.

A loop calibrator sources, measures and simulates the 4 to 20mA current signals that instrumentation uses, letting a technician test and calibrate transmitters, controllers and valves. It is a core tool for commissioning and maintaining process control loops, confirming each device sends and responds to signals correctly.

Use a properly rated voltage tester or indicator, confirm it works on a known live source first, test your point, then confirm on the known source again. This prove-test-prove method ensures the tester itself is working. Always match the instrument's safety category to the environment you are testing.

A voltage tester quickly confirms whether voltage is present and roughly at what level,prioritisingspeed and safety for go or no-go checks. A multimeter measures voltage precisely along with current, resistance and more. Many electricians carry a tester for fast safety checks and a multimeter for detail.

Yes. Accurate readings underpin both safety and quality work, and instruments drift with use, knocks and age. Process meters and loop calibrators in particular must stay accurate to calibrate other devices reliably. We calibrate the test equipment we supply and provide traceable results for your records.

Match the CAT rating to where you work, with higher categories offering greater protection against transient surges nearer the supply. CAT III suits fixed installations and distribution, CAT IV the supply origin. Choose an instrument rated for the highest energy you will encounter, and inspect leads before use.

Yes. We stock voltage testers, phase rotation testers and process meters and ship to electricians, plants and instrument technicians nationwide. Tell us the tasks you handle and the safety category you need, and we will recommend a meter and, where required, a calibration schedule to keep it accurate.
