Extech Instruments announces the release of the EX540 handheld, wireless digital multimeter and datalogger. The EX540 digital multimeter is believed to be the first handheld multimeter to offer wireless data streaming to a laptop or PC for datalogging or real-time monitoring. The DMM is part of the EX500 series of industrial multimeters, considered the "toughbook" of multimeters. The multimeter's ruggedized, waterproof design can withstand a 6-foot drop, making it a good starting point for a go-anywhere DMM. The innovative 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). Now, 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. From a time-saving perspective for laptop users, the EX540 permits a user to set up his or her laptop at a centralized location and then sequentially datalog readings throughout a site without relocating the laptop.
