Wireless DMMs

digital multimeterFluke 233 remote display digital multimeter (DMM) comes with an innovative wireless display. It allows observation 9.1m (30-feet) away from the measurement point.

Fluke CNX 3000 wireless digital multimeter (DMM) is the captain of Fluke wireless team. It displays meter measurement plus readings from up to three wireless modules, as far as 20 metres away. If more than three readings are required from more modules, you can add an optional PC adaptor to your laptop for real-time viewing of up to ten modules.

EXTECH EX540 and EX542 are twelve-function wireless true-rms industrial DMM/dataloggers (up to 9999 readings) with a wireless PC interface.

Smart DMMs

The new range of DMMs offers a new way to perform measurements much more accurately and comfortably with additional features like measurements through mobile applications. Using an app, the user can control any data remotely in real-time using a mobile phone or another mobile device with Android OS.

PROMAX PD-350, PD-351, PD-352 are DMMs with rms and Bluetooth control via an Android app. These also feature smart power-off function, which extends battery life.

OWON DMM – 35 category maintains features like voice warning supported to assure measurement safety, smart voice-reading, smart power-off option extending battery life, supports mobile device with Android 4.3 or above/iOS 7.0 or above and is equipped with BLE 4.0 module.

Keysight meter logger for Android smartphones and tablets improves productivity and safety by allowing the user to stream measurements in real-time from up to three Keysight DMMs and clamp meters wirelessly.

What Future Holds For Digital Multimeters

For the most part, the future of digital multimeter (DMM) will evolve slowly as these are well-establish, general-purpose test equipment that do not need to conform to rapidly-changing applications are. For such applications or those that need to address certain parameters, there will be more specific meters. They will address the needs of each application requirement and the resulting instrument would not be called a DMM.

Where you will see some changes to digital multimeter (DMM) in future will be inclusion of more memory for logging and graphing of data, along with wireless transmission of said data.

  1. The article seems mostly about general electrical applications.
    Electronics field requires micro and milli range of voltages and currents, among other things.
    The ability to select a wide range of voltages, currents and ohms are important.
    You would realise the problem only when you cannot measure small signals (milli volt/current) of a BJT or JFET or sensor.
    Also, test leads/probes along with saftey ratings should be flexible and strong.
    These points have not been covered.
