BSIDE ACM91 BSD-MT6021 6000-Count AC/DC Clamp Meter

The BSIDE ACM91 BSD-MT6021 is a 6000-count clamp meter for AC/DC current and a range of electrical measurements. Its listed clamp-current sensitivity is 1mA, and the feature set includes temperature, capacitance, resistance, frequency and non-contact voltage alert functions. The listing gives conflicting dimensions and weight, so confirm those details and the exact kit before buying.

At a glance

The listing claims 1mA sensitivity for AC/DC current measured by clamp, with current ranges up to 100A.
A dual-line display is claimed to show AC voltage with current or temperature in Celsius and Fahrenheit together with frequency.
Functions listed include capacitance, resistance, continuity, frequency, temperature, low-impedance voltage and V-alert.
The probe-holder slot and rear clip are intended to make storage and one-handed use easier.

Pros and cons

Pros

Combines clamp-based AC/DC current measurement with test-lead functions such as voltage, resistance and capacitance.
The stated 6000-count display and auto-ranging offer a broad set of readings without limiting it to current measurement.
Customer feedback reports useful functionality, although accuracy feedback is mixed.

Cons

The claimed 100A maximum current may not suit work requiring higher current ranges.

What to know before buying

Listing details to confirm

The listing is inconsistent about size and weight: the details section gives 17.9 x 6.7 x 3.9 centimetres and 156 Grams, while the description gives 179mm x 67mm x 36 mm and 137g. It also describes both dual-line display combinations and does not confirm the selected package contents. Confirm these listing details before purchase.

Who is it for?

A good fit for

Buyers seeking one compact instrument for clamp current readings and common multimeter functions.
DIY users who need temperature, capacitance, continuity and frequency functions in addition to voltage and current readings.
Users who prefer a rear clip and an on-device probe-holder slot for carrying and handling.

Less suited to

Buyers who need a stated current range above 100A.
Anyone who needs the dimensions, weight or bundled accessories confirmed before ordering.

Customer feedback says the meter works well and is considered good value, while accuracy receives mixed feedback. That matters for buyers relying on the listed measurement functions, especially where readings need to be dependable. Feedback does not establish measurement accuracy, so treat the stated ranges and accuracy figures as listing claims rather than verified performance.

Positive themes

Customers report that the meter works well.
Customers mention good value for money.

Mixed feedback

Customer feedback on accuracy is mixed.

Frequently asked questions

What current range does the listing specify?

The description gives AC and DC clamp-current ranges of 6A, 60A and 100A. It also claims 1mA sensitivity for clamp measurements.

What else can the BSD-MT6021 measure?

The description lists AC/DC voltage, low-impedance voltage, resistance, continuity, capacitance, frequency and temperature, as well as live-wire check and V-alert.

Are batteries included?

No. The description specifies two 1.5V AAA batteries and says they are not included.
