A True RMS meter is a precise instrument that measures the effective value of an AC or DC current or voltage, irrespective of the waveform. This is crucial because waveforms that are non-sinusoidal, like those produced by electronic devices, can have an RMS value that significantly differs from their peak or average value.

The ProsKit MT-3109 is a cost-effective True RMS multimeter that is versatile enough for various electrical testing applications. It boasts a display with a 6000-count capacity and is capable of measuring AC and DC voltage, current, resistance, capacitance, frequency, and duty cycle. Additionally, it comes with several other features such as data hold, auto-ranging, and a backlight for ease of use.

If you’re in the market for an accurate and affordable True RMS multimeter, the ProsKit MT-3109 is a solid choice.

The ProsKit MT-3109 is not just a multimeter, but also a digital clamp meter that can measure AC and DC current, frequency, and capacitance, making it an essential tool for any electrician.
