The Extech MM750W is a Wireless Datalogging CAT IV True RMS Multimeter offering 14 measurement functions, including non-contact AC voltage detection and Type K temperature measurement. Its defining feature is wireless operation: paired with the included Bluetooth Datalogging Module and the free ExView W-Series App, the meter transmits readings in real time to a smart phone or tablet, stores over 15,000 readings for wireless transfer and report generation, lets the user attach notes and readings to photos taken with the device camera, and turns the smart device into a second display for easier viewing or sharing.

An oscilloscope shows waveforms; a digital multimeter answers the everyday questions of the electrical bench and field — voltage, current, resistance, continuity, and more — in a single handheld instrument. The MM750W extends that role with True RMS for accurate AC measurements and a dedicated AC µA function called out for HVAC flame rod current measurement. The 6000-count backlit display, MIN/MAX/DIF capture, Relative Mode for capacitance zero and offset adjustment, and Data Hold support both quick spot checks and longer documented measurement sessions.

ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.
