Klein Tools MM2000 Electricians/HVAC TRMS Multimeter

Yes, the MM2000 is a True RMS meter, so it reads the actual value of a distorted or non-sinusoidal waveform rather than assuming a clean sine wave. That is what you need on VFD-driven motors, electronic ballasts, LED drivers, and switching supplies. An averaging meter can be off by a wide margin on those same loads.

A thermocouple is in the box, so the MM2000 does temperature straight out of the package. That is the reason this one is sold as an electricians/HVAC meter rather than a straight electrical tester, since HVAC techs need supply and return air temps alongside their voltage and current readings. Test leads and batteries are also included.

Drop protection on the MM2000 is rated to 6.6 feet, or 2 meters, which covers a fall from a ladder step or off the top of a panel. Ingress protection is IP20, meaning it is guarded against fingers and solid objects but has no water rating, so it is a dry-location and indoor-mechanical-room meter, not one to leave out in the rain on a rooftop unit.

The display is backlit, so readings stay legible in an unlit mechanical room, an attic, or a crawlspace where you are working off a headlamp. It also has an analog bar graph alongside the digits, which tracks a changing signal faster than a numeric readout can and is what you want when you are watching a value drift or hunting an intermittent connection.

The MM2000 measures current through its leads up to 10A, which handles control circuits, blower taps, and small loads. It cannot read a compressor or condenser fan draw without breaking the circuit, and those pull past 10A on most units. For in-rush and running amps on the line side of equipment, pair it with a clamp meter and keep the MM2000 for voltage, temperature, resistance, and continuity work.

The manufacturer part number is MM2000, sold by Klein Tools as the Electricians/HVAC TRMS Multimeter. It is a single-model item with no finish, range, or kit variants to specify, so the part number alone is the whole order.
