Fluke | Non-Contact Voltage Detector 90–1000V AC | Pocket-Sized CAT IV 1000V
The Fluke 1AC-II is a non-contact voltage tester rated 90–1000V AC, designed to detect energized circuits through insulation without bare-conductor contact. The 1AC-II operates via an electrostatic field sensor, lighting a red tip and sounding an audible beep when voltage is present. It complies with Australian electrical safety standards and is certified to CAT IV 1000V overvoltage rating, the highest category of protection for this tool class.
Quick voltage verification on the job is often the first step after isolating a circuit. Electricians and maintenance technicians value the 1AC-II for its speed on site: it takes seconds to confirm a supply is de-energized before working on outlets, switchboards, or distribution boards. The rugged pocket-sized form fits toolbelts and van drawers, and the continuous self-test (periodic double-flash visual indication using Fluke Voltbeat technology) confirms the unit is working before each use. No complex setup, no calibration. Just touch the tip to the conductor or terminal, and the tester immediately indicates energized or de-energized status.
Trade-proven design and margin play support the 1AC-II as a standard first-line tester for licensed sparkies. The Fluke brand commands customer confidence and retail margins that reward stocking and specifying the tool. Battery operation (2 included AAA cells) means no downtime waiting for recharge, and the straightforward two-year warranty covers manufacturing defects on the original purchase. Fluke's international standing means technicians moving between jobs or regions can rely on the same detection method and physical form.
Features
- Red LED tip with beeping audible alert — glows red and beeps when voltage is detected, optional mute mode for quiet environments where sound distraction is a concern.
- Wide voltage detection range 90–1000V AC — covers domestic 240V, commercial supplies, and industrial higher-voltage switchboards from a single tester.
- CAT IV 1000V safety rating — highest overvoltage category protection, rated to withstand transient surges from primary supply level (electricity meter or utility service).
- Non-contact electrostatic field sensing — detects ac voltage through insulation without requiring direct contact to bare conductors, reducing arc and shock hazards.
- Continuous self-test using Voltbeat technology — periodic double-flash visual indication confirms the unit and battery are working properly before each use.
- Pocket-sized form factor with blade or round detector tip — fits toolbelts, tradies vans, and shirt pockets for grab-and-go accessibility on-site.
- IP 40 enclosure rating — dust and splash resistant, suitable for general workshop and jobsite environments, not waterproof or submersible.
- 2 AAA alkaline batteries included — battery operation provides immediate use and uninterrupted field deployment without charging delays.
- Audible/Silent mode toggle — beeper can be disabled for use in quiet environments where audible feedback is distracting or inappropriate.
- Rugged construction — built to withstand on-site handling and jobsite falls typical of electrical contracting work.
- Two-year manufacturer warranty — covers manufacturing defects on domestic and commercial use with straightforward replacement or repair path.
- Not suitable for detecting random electrostatic discharge — responds only to steady-state ac voltage fields, not static buildup or ESD spikes.
Where to use
- Power outlets and wall GPOs — quick verify of energized or de-energized status on domestic 10A, 15A, and 20A outlets before installing or replacing power points.
- Switchboards and circuit boards — detect live terminals on distribution boards, sub-boards, and control panels before troubleshooting or maintenance work.
- Extension leads and power cords — confirm whether a supply lead carries voltage when testing damaged leads or investigating appliance faults.
- Rental properties and turnover work — rapid outlet verification during property inspections, tenant changeover, or quick electrical checks on portable appliances.
- Workshop and tradies tool kits — standard carry item for electricians, maintenance technicians, and service personnel who test circuits multiple times daily.
- Safety compliance audits — used in workplace safety inspections and electrical compliance checks where rapid live-circuit detection is required.
- New installations and renovation sites — confirm circuit status during installation of outlets, switches, and appliances in domestic and light commercial renovations.
The Fluke 1AC-II is not suitable for detecting low-voltage control circuits below 90V AC (a separate 20–90V model is available for this application). It does not respond to random electrostatic discharge or static buildup and is not waterproof, so it must not be used in fully submerged or continually wet environments.
