Wireless Datalogging Multimeter with 14 Functions - with NIST

Extech’s MM750W fully loaded rugged Wireless Datalogging Multimeter with 14 functions, includes non-contact AC Voltage detection and Type K Temperature measurement. Using the wireless feature, Bluetooth® Datalogging Module, and the free ExView® W-Series App, you can transmit readings in real-time to your smart devices, store over 15K readings for wireless transfer to generate a report/data analysis, add notes and readings to photos taken from your smart device camera, and use your smart device as a 2nd display for easy viewing or sharing. Smart meter that does not require a clipboard/notepad on the job!
