TRMS SYSTEM Multimeter, Extremely Rugged, Impact-Resistant, Water-Proof and Dust-Proof, and is Resistant to Extreme Temperatures

The METRAHIT AM XTRA is the top-of-the-line instrument of the METRAHIT Advanced Multimeter series.

The multimeters of the METRAHIT AM series, including METRAHIT AM BASE, PRO, TECH and XTRA, are extremely rugged, reliable digital multimeters with housings made of impact-resistant plastic. They feature an appealing design and are equipped with state-of-the-art technology.

  • TRMS SYSTEM Multimeter, Extremely Rugged, Impact-Resistant, Water-Proof and Dust-Proof, and is Resistant to Extreme Temperatures
  • TRMS SYSTEM Multimeter, Extremely Rugged, Impact-Resistant, Water-Proof and Dust-Proof, and is Resistant to Extreme Temperatures

The OUTDOOR multimeter has been specially designed and manufactured to meet the challenges faced by engineers and technicians in adverse environments. It´s extremely rugged, impact-resistant, water-proof and dust-proof, and is resistant to extreme temperatures.

METRAHIT OUTDOOR Technology and scope of functions are the same as with the METRAHIt AM XTRA.

Product Highlights

  • TRMS AC, AC+DC measurement up to 20 kHz for voltage and current
  • Data logger and IR interface for PC
  • Power pack connector socket

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.
