AMM-1221 Digital Multimeter

AKTAKOM AMM-1221 digital multimeter provides precision measurement accuracy (up to 0.1%) and wide functionality at an affordable price. Large LCD display with backlight: 4 1/2 digits, 22000 counts. TrueRMS measurements: 40 Hz to 10 kHz. Basic accuracy 0.1%. Input impedance ≥10 MΩ. Measurement speed 2 times/s.

AKTAKOM AMM-1221 digital multimeter provides precision measurement accuracy (up to 0.1%) and wide functionality at an affordable price. Due to the capability of TrueRMS measuring AMM-1221 multimeter correctly measures non-sinusoidal signals at 40 Hz to 10 kHz frequency range.

In addition to the usual measuring functions for portable multimeters AMM-1221 multimeter is capable of measuring duty cycle and temperature (using K-type thermocouple).

  • Large LCD display (69 x 52 mm) with backlight: 4 1/2 digits, 22000 counts
  • TrueRMS measurements (40 Hz...10 kHz)
  • Basic accuracy 0.1%
  • Input impedance ≥10 MΩ
  • Measurement speed 2 times/sec
  • Analog scale 45 segments
  • Automatic and manual range selection
  • Hold current values
  • Recording maximum and minimum values
  • Relative measurement mode
  • Diode and continuity test
  • Low battery indicator
