Digital multimeter handheld device for NCV non-contact voltage detection and temperature measurement, featuring Bluetooth connectivity options, 600V AC/DC voltage ranges, 20A DC current measurement, and 5999 count LCD display powered by AA batteries
Digital multimeter with NCV non-contact voltage detection and temperature measurement capabilities including Bluetooth variants

This handheld digital multimeter provides comprehensive electrical measurement functions suitable for both professional electricians and DIY enthusiasts. Its non-contact voltage (NCV) detection feature allows users to identify live AC voltage without making direct electrical contact, enhancing safety during preliminary circuit checks. Alongside standard multimeter capabilities, the device can measure temperature and includes Bluetooth connectivity options in specific model variants, enabling data transfer to compatible devices for record-keeping and analysis purposes.
Features and Construction

The multimeter incorporates several measurement ranges and functional capabilities designed for practical electrical testing applications. With different model variants available, users can select between Bluetooth-enabled and standard versions depending on their data transfer requirements.
Material and Build
Constructed with a durable plastic housing typical of handheld multimeters, the device is designed for portable use across various work environments. The electronic components include precision measurement circuits capable of detecting voltage, current, capacitance, and temperature values. The 5999 count LCD display provides clear digital readouts of all measurements, while the intuitive control interface allows straightforward function selection between different testing modes.
Size and Practical Fit
The handheld design offers convenient portability for on-site electrical work, maintenance tasks, and home DIY projects. Standard AA batteries power the device, providing flexibility in power source replacement without requiring specialised chargers or proprietary battery packs. The compact form factor allows storage in toolboxes or work bags alongside other testing equipment, while remaining large enough for comfortable handling during extended testing sessions.
Uses and Placement

This multimeter serves multiple practical applications across residential, commercial, and industrial electrical systems. The combination of NCV detection with standard measurement functions makes it particularly useful for preliminary safety checks followed by detailed circuit analysis.
Event or Professional Use
For professional electricians and maintenance technicians, the device offers reliable voltage detection up to 600V AC/DC and current measurements up to 20A DC. The NCV function provides initial safety verification before working on circuits, while Bluetooth-enabled models (OW16B, OW18B, OW18E) allow measurement data logging for client reporting or compliance documentation. Temperature measurement capabilities support troubleshooting of overheating components in electrical panels and machinery.
Everyday Home Use
Homeowners and DIY enthusiasts can use the multimeter for basic electrical system checks, appliance testing, and automotive electrical work. The non-contact voltage detection provides reassurance when checking outlets, switches, and light fixtures, while standard functions help diagnose battery conditions, test continuity in wiring, and measure capacitor values in electronic repairs. The straightforward operation with AA battery power makes it accessible for occasional users without requiring specialised electrical knowledge.
Benefits and Buying Value

This digital multimeter combines multiple measurement functions in a single handheld device, reducing the need for separate testing equipment. The availability of both Bluetooth and non-Bluetooth variants allows users to select the appropriate feature set for their specific application requirements.
