The Extech DVA30 Non-Contact AC Voltage and Current Detector is a compact, professional two-in-one electrical testing tool designed to detect both AC voltage and AC current without direct electrical contact.
Designed for electricians, HVAC technicians, maintenance teams, facilities professionals, and field service technicians, the Extech DVA30 helps users identify live conductors, trace current flow, locate concealed wiring, and perform quick electrical safety checks.
The Extech DVA30 is ideal for professional use in:
- Electrical troubleshooting
- HVAC service work
- Facilities maintenance
- Building maintenance
- Electrical inspections
- Wiring checks
- Circuit tracing
- Control panel inspections
- Maintenance diagnostics
- General AC voltage and current detection
The DVA30 detects AC voltage from 12 V to 600 V AC and AC current from 200 mA to 1000 A.
This gives users a wide detection range for common electrical testing and maintenance applications.
The non-contact design allows users to detect the presence of voltage or current without cutting wires, opening circuits, or making direct contact with energized conductors.
This makes it useful for checking:
- Live wires
- Hot conductors
- Electrical terminals
- Circuit breakers
- Junction boxes
- Control panels
- Conduits
- Shielded wires
- Concealed wiring
- Current-carrying conductors
A key advantage of the Extech DVA30 is its ability to detect both voltage and current in one handheld tool.
Many standard voltage detectors only identify voltage presence, but the DVA30 is designed to detect AC current as well.
This makes it especially useful when tracing current flow or checking conductors where voltage-only testing may not provide enough information.
The DVA30 can help users trace current-carrying conductors behind walls, in conduit, through concrete, or underground.
It can also help locate hidden wires in walls and floors, identify hot wires, and support safer troubleshooting before further electrical work is carried out.
The detector uses audible and visual indicators to alert users to the presence of voltage or current.
When AC voltage or current is detected, the beeper sounds and the LED flashes, giving a clear indication that a live or current-carrying source is nearby.
The Extech DVA30 includes adjustable sensitivity, allowing users to increase or reduce the sensor trigger threshold depending on the application.
This helps users narrow down the detection area and better locate the source of voltage or current.
Adjustable sensitivity is useful when working around:
- Multiple conductors
- Crowded electrical panels
- Conduit runs
- Junction boxes
- Shielded wiring
- Concealed wiring paths
- HVAC control circuits
- Low-voltage signal areas
The sensitivity is high enough to detect low-voltage HVAC or similar signal levels, making the DVA30 especially practical for HVAC service and electrical maintenance work.
The compact, pen-style design makes the detector easy to carry and convenient to use on site.
The included pocket clip allows users to keep the DVA30 close at hand in a pocket, tool pouch, or work bag.
Built for professional use, the Extech DVA30 is CAT III-600 V rated and CE and UL certified.
This makes it suitable for use in rated electrical environments when used correctly and within its safety category.
The DVA30 is a practical tool for quick checks before working on electrical systems, tracing conductors, identifying energized areas, and supporting daily maintenance tasks.
