Extech Instruments recently announced the Extech EX540 wireless digital multimeter and datalogger, which is the first handheld multimeter to offer wireless data streaming to a laptop or PC for datalogging or real-time monitoring, the company says. The new DMM is part of the EX500 series of industrial multimeters, considered the “toughbook” of multimeters. Extech’s ruggedized, waterproof design can withstand a 6-foot drop, making it the ideal starting point for a go-anywhere DMM.

The new meter offers wireless connectivity to your laptop or PC using a USB receiver with a range comparable to Bluetooth (10m/33 ft). The EX540 transmits real-time data for monitoring, trending and analysis (using the included software) on one of two available frequencies (433 and 914 MHz). So electrical professionals can monitor and datalog readings at a safe distance from hazardous locations. Additionally, it is easier to perform remote tasks such as powering up a device from a control panel that is not nearby. 

Extech is a True RMS DMM that can log up to 9,999 readings internally and also reads voltage, current, resistance, capacitance, frequency (with dual-range sensitivity for electrical and electronic work), duty cycle (dwell), continuity, diode testing (2.8V), and even temperature (using its Type K thermistor bead probe). 

The new meter features 0.06% accuracy, and it is backed by a Category IV overvoltage safety rating, protecting users even on outdoor wiring.

Several one-button statistical data functions include minimum/maximum, relative, hold, and peak hold as well as selectable auto-ranging or manual-ranging. An analog-style bargraph complements the EX540’s informative triple-reading display.
