New meters provide even more choice and value and complement the existing clamp meter lineup

Extech Instruments, a world leader in test and measurement tools, has launched the MA44x series of 400A clamp meters. The three models offer comprehensive multimeter functions and a built-in non-contact voltage (NCV) detector to meet the exacting needs of electrical contractors and HVAC/R technicians.

The MA440 measures AC current up to 400A, DC and AC voltage up to 600 volts, resistance, capacitance and frequency. The MA443 adds True RMS measurement, for the accurate reading of non-sinusoidal waveforms, and thermocouple temperature measurement. In addition to these, the MA445 measures DC current up to 400A, which makes it the ideal clamp meter for professional residential and commercial applications such as automotive, heavy equipment and marine DC current measurements. All three models are rated CAT III – 600V.

Having a type-K function is useful for applications requiring temperature measurements.

The MA443 and MA445 provides instant illumination for workplace areas with poor lighting and come with type-K bead thermocouole

Features

  • Large character 4-digit (4,000 count) backlit LCD display
  • Auto power-off for extended battery life
  • NCV (Non-Contact Voltage) detector function
  • MA44x series meters come ready to use with three AAA batteries, test leads, and storage pouch

Presence of NCV function helps in quickly identifying the presence of voltage on live wires. This safety feature provides extra value by eliminating the need for a separate tester and reduces tool bag clutter. Additionally, the series features duty cycle and diode/continuity measurement.

All three meters feature a jaw size of 1.2” (30 mm) to accommodate up to 500MCM conductors and are therefore suitable for most users in electrical, HVAC/R and electronics design, installation, testing and repair.
