Pricing and Availability
The ANENG DM850 is widely available on marketplaces like AliExpress, Banggood, and Amazon, often priced between $5 and $15. Some users have reported purchasing it for as low as $3.20 during sales. At this price, it is one of the most affordable digital multimeters on the market.
Features and Performance
Basic Measurement Functions
The DM850 covers the essentials: voltage, current, and resistance. It does not have auto-ranging; users must manually select the range via a rotary dial. This is typical for budget meters but can lead to incorrect readings if the wrong range is chosen. Accuracy is modest, with typical tolerances of ±2% to ±2.5%, which is adequate for basic troubleshooting but not for precision work.
Build and Ergonomics
The meter is lightweight and compact, making it easy to carry in a pocket or tool bag. The casing appears to be made of ABS plastic and is available in red or yellow. It includes a fold-out stand for hands-free viewing. The LCD is clear but lacks backlighting, which may be a drawback in dimly lit areas.
Additional Functions
Beyond basic measurements, the DM850 offers diode testing, hFE (transistor) testing, and continuity with a buzzer. These features add value for hobbyists working with electronic components. However, the continuity buzzer is not latched, meaning it only beeps while continuity exists, which is standard for this price range.
User Experiences
User feedback on the ANENG DM850 is mixed. Many appreciate its ultra-low price and basic functionality for occasional use. However, some users have reported issues with resistance measurement accuracy, particularly in the 200Ω and 2kΩ ranges. One user on the EEVblog forum noted that shorting the test leads in the 200Ω range resulted in erratic readings between 30Ω and 100Ω. DC voltage measurements, however, were reported as accurate compared to higher-end meters like Fluke.
Other users have praised its performance for automotive and household diagnostics, with some claiming it matched more expensive meters in basic tests. The lack of auto-ranging and backlight are common criticisms, but these are expected at this price point.
Pros and Cons
Pros
- Extremely affordable
- Compact and lightweight
- Measures voltage, current, resistance, and more
- Includes diode and transistor testing
- Clear LCD display
Cons
- No auto-ranging
- No backlight
- Accuracy issues reported in low resistance ranges
- Battery not included
- Limited overload protection
- Not suitable for professional or high-precision work
Summary
The ANENG DM850 is a budget-friendly digital multimeter that covers the basics for DIYers and hobbyists. Its low price makes it an attractive entry-level option, but users should be aware of its limitations, particularly in resistance measurement accuracy and lack of auto-ranging. For occasional household tasks or learning electronics, it can be a worthwhile purchase. For professional or frequent use, investing in a higher-quality meter is advisable.
