Extech MA445 True-RMS AC/DC Clamp Meter with NCV & Type K Temperature
The Extech MA445 True-RMS AC/DC Clamp Meter with NCV & Type K Temperature can be used to measure the following electrical and environmental parameters:
- AC current
- DC current
- AC voltage
- DC voltage
- Capacitance
- Resistance
- Frequency
- Temperature
This instrument is also capable of performing diode/ continuity tests and duty cycles as well as non-contact voltage measurements. The Extech MA445 True-RMS AC/DC Clamp Meter’s true-RMS capabilities make it suitable for reading non-sinusoidal waveforms; furthermore, its ability to measure DC current makes this clamp meter suitable for automotive applications.
In addition to this, the Extech MA445 True-RMS AC/DC Clamp Meter includes a number of functions optimised for use with various measurement modes:
- Relative mode for capacitance
- DC Zero function
- Data Hold
- Max/ Min
This instrument also features an Auto Power Off function (which may be disabled if required) and a Low Battery indicator optimised for reducing downtime.
Also adding to the Extech MA445 True-RMS AC/DC Clamp Meter’s practicality is its integrated torch and large, backlit LCD display, making it suitable for use in dark environments.
Finally, the Extech MA445 True-RMS AC/DC Clamp Meter’s 1.2”/ 30mm jaws mean that it can be used to measure conductors up to 500MCM.
The Extech MA445 True-RMS AC/DC Clamp Meter with NCV & Type K Temperature is ideal for measuring a variety of electrical parameters and temperatures. It is suitable for automotive as well as troubleshooting and inspection applications.
