The Mastech/Sinometer MY 68 multimeter is a good instrument considering its price. Its deep grey color and strong back support with high-contrast colors make it different from other similarly priced instruments. If you require a multimeter for your profession as an electrician or an engineer you can easily start with this model. Most of your purposes would be served by this instrument.
You can measure voltages in A.C and D.C and the current flow in a circuit with it. Current flow ranges in milli ampere and Ampere and are almost correctly measured by this instrument. It even measures micro amperes with an accuracy of ± 1.50%. You can also measure resistance in ohms. You need to test a diode? This meter has the answer.
A capacitor quality and circuit continuity can be ascertained by this meter as well. Continuity is audibly reported to you from this instrument. Well, you can also test transistors on it. Frequency measurement provision is there in the tester. The My 68 is provided an with autoranging feature on it, so you have to choose the parameter only, not the range. However you have the option for manually setting the range.
This meter has got auto power off feature in it that conserves the battery life (it needs a 9 volt battery). It increases your expenditure on one hand. On the other hand the battery life is much longer than a pencil battery. Thus it nullifies the extra expense. The back tilting arrangement on the instrument makes it easy to see the LCD screen. Although the back support has made it a bit clumsy and heavy to carry it is in all other respects a good choice at the current price point.
The MS8264 is a newly released model from Mastech and there are is no full review available yet. Here is a short summary of the product:
Mastech’s MS8264 is a 30-range (manual) digital multimeter with a full range of features including all the usual functionality and then some; AC/DC Voltage and Current, Capacitance, Resistance, Frequency, Temperature and other features. In short it can be considered an entry-level professional model or a proper product for hobbyists and DIY’ers.
It’s also highly affordable considering the feature set, which also includes back lighting, data hold and a resettable fuse instead of the regular replaceable fuse that renders the unit useless in case you don’t have a spare on hand. It also comes with test leads that have capped tips and shrouded plugs, a K-Type Temperature probe and a multi-functional socket. A 9V battery is pre-installed and it naturally comes with a user manual.

The Mastech MS8261 is a manual 30-range digital multimeter with a solid build and a nice feature set. It’s a middle-of-the-road option with a robust build, targeted primarily at hobbyists.
It comes with all the standard multimeter functions such as Current, Resistance, Capacitance, AC/DC Voltage and so on. It also offer a large display with back lighting to make it easier to read. It is however not auto-ranging like some other models out there today.
However, the resettable fuse and data hold features are nice additions. It is quite affordable considering the feature set and comes with shielded test leads with capped tips. On the whole, it’s a capable product.
