Extech 400 Series
MultiMeters + IR Thermometers
Models EX410, EX411, EX420, EX430, EX450, EX470
  • All models measure temperature. The Extech 450 and 470 include built-in IR thermometer, others accept Type K thermocouple Probes
  • AC True RMS (Models EX411, EX430 & EX470)
  • Audible and visible input alerts
  • MAX (450) and RELATIVE (430/470) functions
  • Low current capability – measure down to 0.1µA
  • Easy to read 1 inch digits on backlit display
  • MAX (Model 450) Hold for AC/DC Voltage and Current measurements and RELATIVE function (Models 430 and 470) for establishing a base line reference
  • IR thermometer has 8:1 distance to target ratio, 0.95 fixed emissivity
Advantages of Non-Contact InfraRed Temperature with laser
  • Troubleshoot - Quickly locate hot spots
  • Distance - 8:1 distance to target ratio allows for measurements in areas that are normally difficult or unsafe to reach
  • Speed - Point and shoot with final result in seconds
  • Convenience - No cables or probes to connect, break or lose.
