Overview
The ANENG 681 is a digital multimeter that has gained attention for its modern design, rechargeable battery, and touch-screen interface. It is part of ANENG's lineup of affordable test equipment, which also includes the 683 model. This review examines the 681's features, specifications, pricing, and user experiences to help you decide if it's the right tool for your needs.
What the ANENG 681 Offers
The ANENG 681 is a handheld digital multimeter designed for electrical testing. Key features include:
- 4000-count display: Provides resolution for measuring voltage, current, resistance, and more.
- Rechargeable battery: Built-in lithium battery charged via USB-C, eliminating the need for disposable batteries.
- Touch screen interface: Operated via on-screen touch buttons, similar to a smartphone.
- Non-contact voltage (NCV) detection: Allows safe detection of live wires without direct contact.
- Auto-ranging: Automatically selects the appropriate measurement range for many functions.
- Additional functions: Measures AC/DC voltage, current, resistance, capacitance, frequency, and temperature (with included thermocouple).
The 681 is often compared to the ANENG 683, which has a higher 6000-count display and faster sampling rate. While the 683 offers better precision for low-voltage applications, the 681 remains a capable general-purpose meter.
Pricing and Availability
The ANENG 681 is widely available on online marketplaces such as AliExpress, Banggood, and other Chinese electronics retailers. Prices typically range from $25 to $35 USD, depending on the seller and included accessories. At the time of writing, it is positioned as a budget-friendly alternative to more expensive brands like Fluke.
Features in Detail
Display and Interface
The 681 features a 4000-count LCD display with a touch-sensitive overlay. The touch screen replaces traditional physical buttons, offering a sleek look but potentially introducing usability challenges, such as accidental changes during measurements.
Measurement Capabilities
The meter measures:
- DC voltage up to 1000V
- AC voltage up to 750V
- DC/AC current up to 10A
- Resistance up to 40MΩ
- Capacitance up to 100μF
- Frequency up to 10MHz
- Temperature from -20°C to 1000°C (with thermocouple)
It also includes diode testing and continuity with audible beep.
Power and Charging
Powered by a built-in 3.7V lithium battery (capacity varies by batch, often around 1000-2000mAh), charged via USB-C. This is a convenient feature, but some users note that rechargeable batteries may degrade over time and are not as easily replaceable as standard AA batteries.
Build Quality and Safety
The 681 comes with a rubber protective cover and a carrying case. However, it lacks advanced safety ratings (e.g., CAT III/IV) found in professional-grade meters. It is suitable for low-voltage electronics work but not recommended for industrial or high-energy applications.
User Experiences
User feedback on the ANENG 681 is mixed. On forums like EEVblog, some users appreciate the modern touch interface and USB charging, while others criticize the touch screen as unnecessary and potentially hazardous during high-voltage measurements. Common praises include its affordability and feature set for the price. Common complaints include:
- Slow continuity response
- Touch screen can be finicky and may change settings unintentionally
- Rechargeable battery may not last as long as disposable batteries
- Lack of advanced safety features
One user noted that the 681's 4000-count display is less precise than the 683's 6000-count, which matters for low-voltage automotive diagnostics. However, for general electronics troubleshooting, the 681 performs adequately.
Pros and Cons
Pros
- Affordable price point
- Rechargeable via USB-C
- Touch screen interface (subjective)
- Includes NCV, temperature, and capacitance measurement
- Comes with protective cover and carrying case
Cons
- Touch screen may be prone to accidental inputs
- No advanced safety ratings
- Rechargeable battery may degrade over time
- Continuity beeper is slow
- 4000-count resolution lower than some competitors
Summary
The ANENG 681 is a budget-friendly digital multimeter that offers a modern touch-screen interface and rechargeable battery. It is suitable for hobbyists and electronics enthusiasts who need a versatile meter for low-voltage work. However, professionals requiring high precision, fast continuity, and robust safety features may want to consider alternatives like the ANENG 683 or more established brands. While it has some drawbacks, the 681 provides good value for its price, especially for those who prefer a smartphone-like user experience.
Before purchasing, check the latest prices and read recent user reviews, as quality control can vary. Overall, the ANENG 681 is a reasonable choice for casual use, but not a replacement for a professional-grade multimeter.
