The first Bluetooth digital multimeter that uses your iPhone or Android as the display

Mooshimeter has developed the world's first digital multimeter and data logger for your mobile device.

The Mooshimeter is a multi-channel, circuit testing, digital multimeter that pairs with your bluetooth enabled smartphone or tablet and utilizes it as a wireless, high-resolution graphical display while logging the results to an internal SD card. With over 10 megaohms of input impedance you can safely measure 600V and 10A all with 24bit resolution and better than 1% accuracy. Additionally, you can use the onboard temperature sensor to measure ambient temperature or compensate for temperature drift, or attach external thermocouples to measure and log temperature changes.

Features

The Mooshimeter allows you to turn your WiFi-enabled smartphone or tablet (Both iPhone and Android are supported) into a high tech, data logging digital multimeter. You can measure AC or DC voltages up to 600 volts, including 420 volts RMS with better than 0.5% accuracy for DC voltages and better than 1.0% accuracy for AC voltages below 1kHz. You can easily measure resistances with better than 1% accuracy over a range from 20 ohms to 20 megaohms. You can measure diodes with an accuracy of 100nA up to 1 volt. The Mooshimeter's digital interface means that you have the ability to perform 8kHz dual simultaneous sampling and can expect 4kHz of analog bandwidth for most measurements.

With on board storage via a microSD card (up to 32GB - which translates to more than a week of constant logging of two channels at 8kHz) the Mooshimeter's data logging ability means you can monitor a project continuously and save the data for a record or later analysis, even without your iPhone or Android device connected to the multimeter. Alternately, data can transmitted to your smartphone or device over bluetooth and saved or viewed in that manner.
