FLIR DM166 Imaging Multimeter

FLIR DM166 Imaging TRMS Multimeter

The FLIR DM166 Thermal Imaging Digital Multimeter provides the user with sophisticated electrical measurement and basic thermal imaging. It can measure AC/DC voltage from 0 to 600V, AC/DC current from 0 to 10A, resistance from 0 to 60MΩ, capacitance from 0 to 10mF and frequency from 0 to 50kHz. The instrument is also capable of performing continuity and diode tests whilst a VFD filter is ideal for measuring variable frequency drives. True RMS improves accuracy on AC values. In terms of temperature, the multimeter can perform thermocouple measurement from -40˚C to 400˚C and there is also a µA range for testing flame sensors.

The FLIR DM166 has a vibrant 2.4” colour screen that can show thermal images in iron, rainbow, or greyscale palettes. The automatic ranging produces an appropriate thermal image for the temperature conditions. When not in thermal imaging mode, readings are clearly shown on the screen and the multimeter takes 5 samples per second. The user selects their chosen function via the clearly-labelled dial whilst other push buttons control the mode, range, data hold function and min/max recording.

The FLIR DM166 is specifically designed to keep the user safe. Not only will the thermal imaging alert the user to faulty components without having to touch them, there is also a non-contact voltage detection function that warns the user of live circuits. The multimeter is rated safe for Cat III 600V and Cat IV 300V and it has a sturdy, ergonomic design which is ideal for performing awkward or challenging measurements. It benefits from a 10-year warranty and has been drop tested to 3m. Test leads, batteries and a soft carry case are provided as standard.

The DM166 Comes Supplied With:

  • FLIR DM166 Thermal Imaging Multimeter
  • L91 Lithium batteries
  • Silicone test leads
  • Soft carry case
