The Mooshimeter is a multi-channel circuit testing multimeter that uses your smartphone or tablet, through Bluetooth 4.0, as a wireless, high-resolution graphical display. Each Mooshimeter is able to safely measure 600V at 10A with 24bit resolution from up to 150 feet away. If you’re curious about the Mooshimeter’s battery life, never fear, the meter uses two simple AA batteries and is capable of logging results for up to 6 months.
Next time you need to check the current on your robot’s motors, connect the Mooshimeter and drive the bot around while viewing (or logging) your current draw. Not only that but with the multi-channel feature you can also measure voltage (and consequently total power) at the same time. You are no longer tethered to your multimeter. With 24-bit resolution you can often skip the amplifier circuit and measure things like heartbeat directly from your Mooshimeter. With this multimeter you will be able to measure DC Voltage up to 600V, AC Voltage up to 420V, DC Current between up to 10A, and Resistance from up to 20M Ohm with better than 1% accuracy. The Mooshimeter is completely capable of being used in applications for sampling power, measuring impedance and current, detecting the temperature, and even tracking heart beats.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I purchased the Mooshimeter about a month ago. The meter is impressively well-built, comes with high quality insulated test probes with plug-in alligator clips for when you need to hook on to some circuit element for extended monitoring.
It took me an hour or so of reading the instructions and tinkering to get comfortable with the operation of the device. My first test was to remotely monitor the current and voltage output of a solar panel under various conditions of lighting. Being able to monitor current and voltage simultaneously was a very handy feature for this purpose.
Presently I have the Mooshimeter set up in my workshop, monitoring rectified Radio Frequency Interference levels, as received on a short-wave receiver operating there. The workshop is about 60 feet from the house. I suspended the Meter in front of a window in order to receive the strongest signal over that distance, and stand near a window in the house with my iPhone to check the voltage levels in question. As a bonus I can check the temperature in my shop, though response in this case is rather slow since the Mooshimeter’s temperature sensor is buried inside the case.
The Mooshimeter is well-worth its price and I have no reservations about recommending it to anyone who requires a compact multi-meter capable of being monitored from a distance.

Very well constructed, very accurate, very intuitive to use. The graphing function is lovely.
Doesn’t come with a manual, get that plus tips & tricks at: https://moosh.im/documentation/
This won’t replace your multimeter for immediate “one-off” measurements (you need a separate smartphone or tablet to get readings), but it is wonderful for remote sensing and watching volts/amps/ohms change with time & conditions.
The one major flaw, which I hope will be fixed in firmware soon, is that the logging function is effectively useless in the current device iteration- it only logs to a micro SD card (not included), and you can only retrieve the log by unscrewing the case and pulling the SD card out to read it on a separate computer- you cannot access the SD card, either physically or to transfer the data, from outside the case. There is no “read log data” function in the Android or iOS software.
The case in the currently shipping device does have a slot cut out for SD access (on one side), but unfortunately that access is blocked by a flap on the other side of the case. From the dialogue on the web site, I guess this is due to regulatory requirements for this high voltage test device. You can cut off this blocking flap, to access the SD without taking the case apart, but even then it is difficult to pull the SD out, because it doesn’t pop out far enough to easily grab, with the case in place. I solved that with a thin strip of adhesive tape attached to the uSD, sticking out of the case…
A much better solution would be for the logged data to be downloadable via Bluetooth to your display device, so that you would never need to mess with the SD card after installing it… I can’t imagine why that has not been implemented. A nearly fatal flaw, for a device otherwise perfectly designed as a remote sensing & logging instrument.
Still- a very nice and handy device, almost a must have for your tool bench…
UPDATE 9/10/16 after 3 months use: some teething pains, but I am liking this meter more and more. Of special note is that the developer is very active in supporting users- if you post to the support forum at https://moosh.im, you are likely to get a personal response within hours or even minutes.
I should mention a particular problem that has affected many early adopters (including me): the battery clips used on some early units had burrs that could short out a battery. The symptom was that you might find one battery totally dead (0 volts), while the other battery was still fine. That’s been fixed for newer units (new battery clips from a different manufacturer), but if you experience this problem, see the support dialogue at https://moosh.im/2016/09/short-circuiting-battery-problem/
Have fun- joel.

Just received the Mooshimeter and I am very impressed. The case seems to be high quality. The test leads are excellent, well made, very flexible. I really like the tip protectors.
The app is very easy to use, no problems connecting the Mooshimeter to my phone.
I tested the Mooshimeter against my voltage, current and resistance standards (from voltagestandard.com - highly recommended). The Mooshimeter was very accurate, in all cases better than the specifications.

Interesting device. A little buggy in the software though. The firmware download is squirrely though, took a few attempts with different devices to get it to work. I was particularly interested in the logging feature, and it works, but also a little flakey: The interval that you program in kinda stays, but it will either not stick or change during a measurement run, which can be a pain when analyzing data.
Shows tremendous promise.

Loaded software for I phone and it works as advertised. Will add another review after I use it for a while.
Very simple to deal with and powerful at the same time.
So good wished I had found it years ago. Going to get a couple more. Saves so much time.
Original batteries leaked, damaging the circuit board. Meter was in sleep or storage mode, and stored inside house. $120 wasted. And now I see that moose.im web site system is offline. Company out of business?
I’m sorry to hear that your batteries leaked. Unfortunately any AA cell can leak if left alone for an extended period of time. Mooshimeter is still in business and you can find them at https://moosh.im/mooshimeter. You might try contacting them to see if there is anything that can be done to revive your meter.
I needed to measure the voltage and current across two points where either one could go positive or negative. This worked great! And anyone using the system could check current and voltage on their own phone!

I was really excited about this meter, but easy 95% of the time the app crashes and won’t work. I’ll probably return it if possible.
Hmmm, we haven’t seen issues with these. I’d suggest getting in touch with our tech support team, they should be able to help resolve any issues you’re having.
I saw this product online and thought I’d take a risk and buy one. I need to take current and voltage measurements and log results - this has made my life so easy. I can see on my mobile what’s happening and from my mobile send myself the log files. Brilliant!
The Mooshimeter does exactly what it promises to do. Installation on an Android device was frustrating at first since the firmware bootloader never seemed to finish installing. After a complete installation of the firmware, reinstalling the Mooshimeter app on my phone solved the problem.
Used it several times on high voltage boards while staying at distance. Measuring resistance without having to walk up and down to the control panel. Used it to log the battery level and consumption of a wheel loader while continuing other tasks. Easy to use, bluetooth connectivity works flawless,…etc
