Our METRAHIT AM SERIES include rugged, reliable digital multimeters with housings made of impact-resistant plastic. They feature a new design and are equipped with state-of-the-art technology.

Product Highlights

  • 23 multimeter functions
  • Voltage AC TRMS, voltage AC+DC TRMS,voltage DC, frequency (Hz, MHz), duty cycle, resistance, diode test, continuity test, capacitance, current AC TRMS, current AC+DC TRMS, temperature with Pt 100/1000 sensors and type K thermocouples
  • Auto-range current measurement from 100 μA (resolution: 10 nA) to10 A (16 A) via a single connector jack and a single fuse
  • Additional filter function and voltage measurement with reduced input impedance for limiting interference, e.g. for measurements at frequency­ converters
  • 540 kB data memory (15,400 measured values) for long-term measurements with data logger function
  • Power pack connector socket for operation without batteries
  • Infrared interface for communication with the PC
  • Rubber holster safeguards against shocks and impacts

Your advantages

  • Universal use in all fields of electrical engineering!
  • TRMS measurement up to 20 kHz with digital display (12000 digits) and analog scale
  • Measurement of voltage and current, DC, AC and AC/DC, resistance, temperature, frequency, duty cycle, capacitance, continuity/diodes
  • Automatic measuring range selection and measured value storage
  • Safety for the user and the instrument in measuring categories CAT IV up to 600 V and CAT III up to 1000 V.


The multimeter is suitable for universal use in electrical engineering, electrical installation, laboratory applications, telecommunication, training etc.

The instrument can be used in the field and is equipped with an internal, mains-independent power supply. The additional power pack connector socket is ideal for long-term measurements and laboratory use.
