Overall I am very please with this multimeter's performance. I've had it for little over a month and its performed quite well. Its a great value in my opinion. Review by Pavel Gurvich (Posted on 12/15/2011)
Nice multimeter for a good price
Nice unit, solid body and durable, good # of functions and ranges. For the features-to-price ratio this was very good. Review by william vadino (Posted on 11/15/2011)
Solid body and durable item
Solid body and durable, good # of functions and ranges. The backlight is good too. Review by Philip Weyhe (Posted on 9/2/2011)
The Mastech MS8221 digital multimeter is a good value for the money with quite a number of functions including DC and AC voltage, DC current, resistance, and diode and transistor testing. In addition it measures temperatures (to the nearest F or C degree) and, very usefully, battery life. It comes with a pair of AAA batteries which are inexpensively replaceable and it will turn off automatically if you forget. Review by E. MORRIS (Posted on 2/12/2011)
I tested it with some known value resistors and power supplies and everything was spot on. Just turn the switch to your desired reading and the best value is displayed. You can also manually switch between them with the range button, but I prefer auto range myself. Review by Donald (Posted on 12/14/2010)
