Our Mooshimeter Review

We've been familiar with the Mooshimeter for a while now, we've got tutorials on Getting up and running with a Mooshimeter, how to datalog with your mooshimeter, taking voltage/current measurements with multi-meters and finally a whole article on mooshi-specific maintenance. It's about time we did a full-scale review of the Mooshimeter now that we've got some experience with it. The Mooshimeter is a CATIII 600V Multimeter that uses Bluetooth to display measurements.


Well start off with the physical feel & make of the meter. The casing is a Polycarbonate plastic, moulded case and it's extremely sturdy. Polycarbonate is a composite plastic material that is a lot cheaper than metal or glass to manufacture. To frame that a little better, Polycarbonate is seen in bulletproof 'glass', Compact Discs, Riot shields and heavy duty phone cases. Now, as the meter doesn't come with an LCD screen like a typical multimeter the entire case is solid polycarbonate, the only case openings are around the terminal connectors and screw holes in the back. We're not saying we're throwing this thing around, but it can easily handle rougher handling situations without being damaged, so Mooshimeter have made a great choice in using polycarb on the meter.


The Mooshimeter is essentially three-quarters of your typical multimeter. You don't have an LCD that shows your readings like you do in typical multimeters, it works alongside the relevant iOS/Android application. So the design and user experience of the application is a massive part of the Mooshimeter experience. Our review of the smart-phone application is essentially a derivative of a few things, namely connectivity and simplicity. Your mooshimeter connects to your device using BLE (Bluetooth Low Energy), making it a very easy, select and connect procedure that we were extremely happy with. The Mooshi app also suggests firmware updates as soon as they are available meaning you never have to worry about keeping your firmware up to date. Overall, using the iOS application with an iPhone, we were very satisfied with the simplicity of the app.


The Mooshimeter doesn't just come by itself either, you get a few things with your Mooshimeter. The package contains:

  • 1x Mooshimeter
  • 2x AA batteries
  • 3x 10A 600V CATIII Test Leads
  • 3x Slide-on Alligator Clips
  • Tool Case

So you get everything you need to get started taking measurements, excluding the smart device/application of course.

The range of measurements you can take with the meter is pretty standard. From the app GUI you get these options for each channel:

  • Voltage DC (0-600V)
  • Voltage AC (0-420V RMS)
  • Current DC (up to 10A continuous)
  • Current AC
  • Internal Temperature (using thermistors or thermocouples)
  • Auxiliary Voltage DC
  • Auxiliary Voltage AC
  • Resistance (1% accuracy between 20-20 MegaOhms)
  • Diode Drop (up to 1V @ 100nA)


The meter is also auto-ranging for the measurements you take, which is good to know. But, the impressive part about this unit is you can take two of those measurements simultaneously, as there are 2 24-bit ADCs on board! If you connect the implications of that with say, Ohm's Law, you'll see that this is quite handy; allowing you to take power measurements as a function of Voltage and Current! Sure, there are meters that can do this, but you don't typically see it.

The data logging feature of the Mooshimeter is extremely handy too, allowing you to take logs of your 2 channel measurements straight to the SD card. You can even email the .csv (comma separated values) files from the Mooshimeter application, without having to remove your SD card to retrieve the logs. If you want more information on getting started with data logging on the Mooshimeter, head over to our tutorial. In any case, it's a nice feature to have on a multimeter.


So what's the verdict? The Mooshimeter is actually quite a powerful little multimeter, with a few features you don't see on other multimeter's, especially in its price range. In fact, considering you can take two measurements, this device is essentially performing the function of 2 meters at the same time, so that's also something to take into account. It's a truly innovative piece of tech, meshing well into automotive and robotic applications extremely well.
