Quick verdict
If your work in the multimeters electrical testers space is mostly about everyday electrical checks, the DM850 Digital Multimeter gives you the essential measuring functions in one handheld unit for $12.95. It won't replace a high-precision bench meter, but it gives DIYers and technicians a practical way to get the readings they need on common jobs.
Who it suits
This meter fits anyone who needs a portable, everyday tester for AC and DC voltage checks, DC current readings, and continuity or diode checks. It also makes sense as a spare meter to keep in a toolbag because the data hold makes it easier to read a measurement after the probes are moved away.
What stands out from the listed details
The DM850 covers AC and DC voltage up to 600V, DC current, resistance, and audible continuity with diode testing. The auto-ranging feature means you do not need to work out the correct range before touching the probes. A backlit LCD, data hold, low-battery indication, auto power off, and an HRC fuse with shunt resistor for input protection round out the package.
Meaningful trade-offs
The biggest limitation is the 3-digit LCD, which tops out at 1999 counts. That keeps the meter simple but also limits resolution, so very small changes in voltage or resistance may not show up clearly. The resistance range stops at 2MΩ, which rules out very high-resistance work. If your projects stay within those boundaries, these trade-offs won't get in the way.
DM850 Digital Multimeter
One reason to choose the DM850 is that it fits the most common electrical troubleshooting tasks without demanding a lot of setup. The auto-ranging and backlit display remove two of the usual frustrations with handheld meters. The limitation you should weigh is the 1999-count display: it is fine for everyday readings, but if you need to resolve tiny differences, you will want a meter with more digits. For straightforward checks, the DM850 is a practical tool.
Bottom line
The DM850 Digital Multimeter handles the basics of multimeters electrical testers with a compact layout, a readable backlit screen, and the voltage, current, resistance, and continuity functions most people need for everyday fixes. Its trade-offs are about display resolution and resistance range rather than missing core features. For a straightforward meter at its price, it deserves a place on your shelf.
