Push this into a Danish Type K outlet and the LED pattern tells you whether that outlet has a working earth. It is the check to do before you connect any grounding product to it.

Type K, or something else?

Type K is the long-standing Danish outlet. Newer installations in Denmark may instead have earthed Type E or Type F (Schuko-style) sockets — so look at the outlet before ordering. If yours is Type E or F, the Europe/Schuko tester in the socket tester range is the one that fits, and the matching Europe adapter goes with it.

Specification

  • Socket type: Type K (Danish standard)
  • Detects earth presence, open earth and reversed polarity
  • LED light-pattern display, mains powered — no batteries
  • Impact-resistant plastic housing
  • Will not give you a shock even if the socket turns out to be ungrounded

Using it

  1. Push the tester fully into the Type K outlet and switch the outlet on if it has a switch.
  2. Read the lit pattern against the legend printed on the body.
  3. Repeat on any other outlet you might use — wiring can differ from room to room.

What does the pattern actually tell me?

Which of the three conductors are where they should be. It distinguishes a correctly wired outlet from one with no earth, and from one where live and neutral are reversed.

Do I need batteries?

No. It draws what it needs from the outlet itself, so there is nothing to replace and nothing to go flat in a drawer.

How often should I re-test?

Keep it and re-check after any electrical work or renovation. A circuit that was fine last year can be altered by a rewire you never see.

The tester says no earth — now what?

Do not use that outlet for grounding. Try others in the property, and raise the fault with an electrician. How to test a wall socket covers reading the result in more detail.

Common Questions about Socket Testers

How do I use the outlet checker?

Simply plug it into your wall socket. The indicator lights will immediately show if your outlet is correctly wired and properly grounded, ensuring it is safe and ready to use with any grounding product.

Can I use it with other brands?

Yes. Our outlet tester uses standard connection sizing and accurately measures the ground of any standard wall outlet, regardless of what brand product you plan to plug into it.

What if the lights indicate no ground?

If the tester indicates your outlet is ungrounded, you should not plug your grounding product into it. We recommend testing other outlets in your home or consulting a qualified electrician.
