Clamp Meter App


Extech Instruments announces the release of the new industrial app, “EX845 METERLiNK for Android.” The new app allows electrical contractors and plant maintenance professionals who use Extech’s EX845 clamp meter to remotely view and display readings from the meter on an Android phone or tablet up to 10m or 30 feet away. The new industrial app displays large, easy-to-read values for the following functions: AC/DC voltage, AC/DC current, capacitance, resistance, frequency, diode test, and temperature (both from a Type-K thermistor probe and from the meter’s built-in non-contact, laser infrared thermometer). Function indicators highlight which measurement mode is selected on the meter. Additionally, Data Hold and Min/Max functions are also remotely displayed.  

The METERLiNK app also features a log of recent readings for quick reference, basic trending and more context. The app is available now at the Google Play™ Store app by visiting . 

What is METERLiNK? 

The EX845 clamp meter is equipped with METERLiNK, a Bluetooth-based technology originally developed by Extech and FLIR to transmit real-time electrical readings from the clamp meter directly to FLIR infrared thermal imaging cameras. Now, leveraging the versatility of Bluetooth, any Android device running the new industrial app can also display readings via Bluetooth. 

Remote Display Advantage: 

Now, electrical professionals can monitor voltage, current, and other readings at a safe distance from hazardous locations. Additionally, it is easier to perform remote tasks such as powering up equipment from a control panel that is not nearby. For electricians who must show readings to a customer or manager, the remote display makes it easy to leave the clamp meter in place while showing and explaining findings from a safe location. 

Dual Display Convenience: 

The METERLiNK app allows an EX845 clamp meter to function in a manner similar to test tools with a detachable wireless, remote display. The advantage of the app however is that the display on the clamp meter remains intact and continues to function, displaying readings locally in addition to the remote display on the Android device. 

Expanding the Diagnostic Ecosystem: 

The EX845 METERLiNK™ for Android app is one part of Extech & FLIR’s “diagnostic ecosystem” approach to effective troubleshooting. Extech and FLIR are committed to offering increased connectivity among Extech meters, FLIR infrared thermal imaging cameras and personal devices such as tablets and smartphones. The goal of the diagnostic ecosystem is not only to improve communication among diagnostic and communication devices but also among technicians and their customers and managers, by leveraging accurate and coordinated readings from related tools as well as rapid and actionable communication like tablet-based email reports generated on the fly.
