Extech EX355 True RMS MultiMeter + NCV + Temperature

Extech logo

The Extech EX355 is a professional Digital Multimeter which is loaded with advanced features and functions. Low Impedance (LoZ) mode eliminates false readings caused by ghost voltages.

  • Low Pass Filter (LPF) attenuates high frequencies to reduce noise for accurate readings.
  • True RMS provides accurate readings when measuring distorted or noisy waveforms.
  • Temperature measurement with a K Type thermocouple.
  • Built-in Non-Contact AC Voltage Detector quickly checks for the presence of AC Voltage before testing.
