The Major Tech MT255 is a reliable and easy-to-use power data logger that helps track and record electrical measurements. It measures AC voltage, current, frequency, power usage, and power factor—giving you a full picture of energy consumption. With three recording modes (Interval, Trigger, and Capture), it can store up to 25,350 data points and record for up to 72 hours.
It connects via Bluetooth for real-time monitoring through the Meter-X mobile app (iOS and Android) or via USB for in-depth analysis on a PC. A bright backlit display shows live readings, and flashing indicators signal when it's actively logging data. The built-in clamp adaptor even includes non-contact voltage (NCV) detection for extra safety. Plus, with a magnetic back plate, you can stick it to metal surfaces for hands-free use.
Q: How long can the MT255 record data?
A: It can log data for up to 72 hours, depending on the recording mode.
Q: Can I check data remotely?
A: Yes, you can monitor readings in real-time via Bluetooth using the Meter-X app on your smartphone.
Q: Does it include non-contact voltage detection?
A: Yes, the built-in NCV feature helps detect live circuits without direct contact.
