U1240 Series 4 Digit Handheld Multimeters

Rugged DMMs for installation and maintenance troubleshooting
  • Detect the presence of harmonics in AC supply (motors, generators, transformers) with just a button press
  • Monitor differential temperature points on HVAC systems with just one DMM
  • Increase productivity with wireless data logging via Bluetooth®
  • Dust and water resistant models can withstand a 10-ft drop
  • Includes models with flashlight, low input impedance mode and non-contact voltage detection

Monitor measurements remotely—and safely—via Bluetooth

  • Requires optional Infrared (IR) to Bluetooth adapter, compatible with all U1200 Series handheld DMMs
  • Safely monitor measurements on your PC or iOS / Android mobile devices from up to 100 meters away (Bluetooth Class 1)

Stay productive, efficient—and safe—wherever tasks take you

  • Unwanted harmonics can cause overheating of motors, premature tripping of circuit breakers and blown fuses. With just a button press, the Harmonic Ratio function provides the percentage value of distortion due to harmonics, so you can decide early on if further analysis is necessary.
  • Differential temperature measurements can reveal if a heating, ventilation and air-conditioning (HVAC) system is heating or cooling the way it should, and this can be easily achieved with the T1-T2 function.
