U1240B Series handheld digital multimeters
Installation and maintenance of machinery, electrical systems and more often
require numerous quick checks and xes, sometimes under hazardous conditions.
Whether you need to quickly inspect power supplies for harmonics, detect
glitches in switch systems or monitor differential temperature, the U1240B Series
handheld digital multimeters (DMMs) is up to the task. With all you need in one
portable instrument, you can travel light and nish the day’s work with ease. Plus,
you’ll be glad to know it’s easy to own one, even with the DMM’s rich capabilities.
Features
– Low micro-amp and high Mega-ohm ranges
– Switch/Relay counter for glitch detection
– Harmonic ratio measurement in AC supplies
– Dual and differential temperature measurements
– Data logging to instrument on the go
– For Keysight Remote Link solution, add on optional U1117A Infrared
(IR)-to-Bluetooth adapter to get instant wireless Bluetooth connection
