Highly precise, easy-to-use digital multimeter ideal for all standard measurements of electrical parameters.

The Chauvin Arnoux MTX203 is the upgraded version of the MTX202 with expanded, 6000 count display and expanded measurement ranges on most measurement functions compared to the MTX202.

We'd highly recommend this digital multimeter for use in any basic electrical application, particularly for use by self-employed electricians.

  • AC and DC Voltage Measurements - from 0.6V to 750V (upgraded from MTX202)
  • AC/DC Current Measurements - three ranges: 10μA to 6000μA, 6mA to 600mA and 0.002A to 10A (true RMS on AC to ensure accuracy) (upgraded from MTX202)
  • Diode Test - to 3V with 0.001V resolution
  • Resistance Measurements - from 1Ω to 60MΩ (upgraded from MTX202)
  • Continuity Test - with integrated beeper
  • Capacitance Testing - from 1nF to 100mF
  • Temperature Measurements - (using type K thermocouple) from -55 to +1200°C

Portable, Pocket-Sized Design with Range of Useful Features

Chauvin Arnoux's MTX series multimeters are designed with practical use in mind. The MTX203 combines together pocket-sized design with easy-to-use buttons and rotary dial for quick, seamless access to testing procedures.
