Kyoritsu 6205 Review 
The Pros – Battery powered with built-in RCD testing (no isolation transformer needed). Selectable 250V and 500V insulation testing. Basic data storage with included PC software. Can be used with a printer.
The Cons – Very basic memory with only stores 999 test results.
The Bottom Line – The Kyoritsu 6205 (also known as the KEW 6205) is a solid entry-level PAT tester that packs more punch than most in its price range. It’s one of the few testers under $1500 that’s battery powered, RCD-capable, and can store results for basic logging. Whether you're just getting into test and tag or looking for something simple and portable - this one’s worth a look.
Key Features of 6205 PAT Tester
Battery Power & Portability
Back in the day, battery power was something you only saw in higher-end testers. Now it’s pretty standard – but still a big tick in our books. The Kyoritsu 6205 runs fully on batteries, so you’re not stuck hunting for a power point when you’re on-site. Whether you’re a mobile tradie, working in schools, or just moving between rooms, this little unit’s compact, cordless, and easy to carry. Simple to use, and even easier to lug around.
RCD Testing Built In
A big win for this unit is its built-in RCD testing capability – it can handle both portable and fixed RCDs thanks to an internal isolation transformer. That’s a feature you’ll usually only see on more expensive testers, and it means you don’t need to buy extra gear down the track.
Display & User Experience
The LCD screen is nice and clear, with a colour-coded backlight that flashes green for PASS and red for FAIL. The interface is very straightforward - you’re working with one-button test operations, which keeps things quick and easy.
How It Performs in the Field
If you’re doing regular testing and tagging around schools, offices, or small businesses, this unit fits in nicely. It’s fast, light, and doesn’t feel overwhelming to operate. The test results are easy to read, and it’s one of those PAT Testers that just works without needing a bunch of setup or tech know-how.
You’ll also find that it performs all the core tests quickly - including Class I, Class II, extension leads, leakage current, and both 250V and 500V insulation resistance. That gives it more flexibility than some cheaper models like the Seaward 125 EL or Wavecom TNT EL.
While it technically supports printer connectivity via cable, it’s not a wireless or automated solution - so most users in this range still handwrite tags or use custom pre-printed ones.
Drawbacks to Consider
The 6205 isn’t a fully featured digital system – and that’s okay, as long as you know what you’re getting:
- No wireless functionality – everything’s done manually or through PC connection
- No scanner support
- Memory is basic – stores 999 tests but lacks automation or tagging logic
- No hard carry case included
- No touchscreen or advanced test sequences
If you need something with more powerful workflows or wireless printing, consider stepping up to something like the DeltaPAT 3309 BT or PAC3760 DL.
Is it Worth the Investment?
If you're chasing a dependable, well-built PAT tester that nails the essentials – and throws in RCD testing for good measure – the Kyoritsu 6205 is one of the best options under $1500. It doesn’t do everything, but what it does, it does well.
