The CAT rating is a safety specification, not a quality grade · review
RICOKEY Digital multimeter with stand review
A basic manual-ranging meter covering voltage, DC current, resistance, continuity, battery and diode tests, with a 2.7-inch backlit screen and a fold-out stand.
What the figures leave us with A big screen and a full function list at eleven euros, with the safety specification left out. Keep it for low-voltage work.
A lot of functions, a big screen, and one specification missing.
What the manufacturer publishes
AC and DC voltage, DC current, resistance, continuity, battery testing and diode or transistor P-N junction testing. Overload protection, stated for safe and accurate fault-finding on a range of electrical problems including automotive. A 2.7-inch backlit LCD with data hold. A protective orange case with a built-in fold-out stand.
The specification that is not on the page
Every multimeter carries a measurement category and a voltage — CAT II 600 V, CAT III 600 V, and so on — describing the transient energy it is built to survive at a given point in an installation. It is not a quality grade; it is a safety rating. It does not appear here.
Of the five multimeters in this hub, only one states a category at all. That is a finding about the category as sold, not about this meter in particular, and it is the reason to read the manual before the listing.
Where the fold-out stand earns its keep
A meter lying flat on a bench is a meter being read at an angle, and a meter propped against something is a meter that falls over mid-measurement. A stand is a two-cent molding that changes how the tool is used.

What it has, and what it lacks
Strengths
A 2.7-inch backlit display, the largest screen among the cheap meters here
Includes a battery test and a transistor test, which most meters at this price drop
A fold-out stand, so the meter stands up on a bench instead of lying face down
Overload protection stated
Compromises
No measurement category published — the safety specification is absent from the listing
No true-RMS, so distorted waveforms read low
On sale on the German market only

What gets asked here
What measurement category does RICOKEY state?
None appears in the listing. The category — CAT II, III or IV with a voltage — is the specification describing the transient energy an instrument is built to survive, and it is a safety statement. We do not infer one. Read the manual supplied with the meter and follow it.
Is it true-RMS?
The listing does not say so, which means it is an averaging meter. On a clean mains sine wave that is fine; on the distorted waveform of a dimmer, an inverter or a variable-speed drive, an averaging meter reads low.
What is the transistor test for?
Checking the P-N junctions of a transistor for continuity and polarity. It is an electronics-bench function that has largely disappeared from meters at this price.
Our score
7.0/ 10
A big screen and a full function list at eleven euros, with the safety specification left out. Keep it for low-voltage work.
This one’s price among measuring instruments
A reference exists on these Amazon stores: Germany, United Kingdom, United States. Listed is not the same as in stock — availability changes daily.
Details checked on August 31, 2026.
Who should pick this one, among measuring instruments
Bench and automotive fault-finding at low voltage, where the reading is a presence check rather than a value.
Accessories stated to fit this instrument
Listed because the accessory names this instrument itself.
Amazon reports what buyers took in the month before this page was last checked: at least 1,000.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.

True RMS · 6000 counts · 600 V · temperature, capacitance and frequency
A true-RMS meter with 6000-count resolution and a wide function list — voltage, current, resistance, temperature, diode, continuity, capacitance and frequency — with probe caps included.
Best for: Household and light installation work where waveforms are not clean and the reading has to be right.
19 RANGES, the only range count published on this shelf · 10 MΩ input impedance, stated for automotive computer circuits · automatic POLARITY sensing · automatic zero on volts, amps and battery tests · battery tests at 1.5, 9 and 12 V · the ONLY meter on this shelf sold WITHOUT its battery · NO measurement category
An automotive meter built around the one specification car electronics actually need — a 10 MΩ input impedance.
Best for: Car and bench electrical diagnosis, where the circuits are 12 V and the sensors must not be loaded by the meter
AC/DC voltage · DC current · resistance · diode · double ceramic fuse
A compact meter whose distinguishing specification is its protection: a double ceramic fuse stated as flame-retardant, plus a silicone sleeve, at fourteen euros.
Best for: A first multimeter for household and hobby electronics, chosen for its fusing rather than its features.
