MA440 400A AC Clamp Meter with NIST by Extech
Three models to choose from, with or without True RMS and AC or AC/DC Current functions. Choose True RMS model for accurate readings of non-sinusoidal waveforms, model with DC Current function for automotive applications, or model with Type K function when applications require Temperature measurements. The MA440 Series meters are fully loaded with multimeter functions and built-in non-contact voltage (NCV) detector to meet your application needs!
Features
- 1.2" (30mm) jaw size fit conductors up to 500MCM
- Built-in Non-Contact Voltage (NCV) detector
- MultiMeter functions include Resistance, Capacitance and Frequency
- Relative Mode for Capacitance
- Data Hold freezes reading on display
- Auto Power Off with disable and Low Battery indication
- Large backlit LCD display
- Complete with test leads, three AAA batteries, and pouch; MA443 and MA445 also includes a general purpose Type K Temperature probe
