Basic Electrical HVACR Features

Expandable for Additional HVAC/R Measurements  

  • Microamps for flame diode test
  • Works with accessory heads
  • Dedicated battery check
  • Amps up to 10 AC/DC
  • Backlight

The LT83A is a basic classic style multimeter at a great price.  It’s a manual ranging meter that includes common HVACR electrical parameters. Add our optional detachable test lead set, and the LT83A works with our accessory heads to test non-electrical parameters too. The LT83A meter measures voltage, resistance, amps, continuity and more. Test leads store in the meter body along with the tilt stand and magnetic hanger. The body is constructed of durable ABS plastic and a blue backlight makes the large LCD even more visible. It’s a good, solid meter and a real value.
