Question: is a case included
Document: I love my K-II Meter. It works very well. Came battery included and ready to use. Looking forward to using it on a ghost hunting investigation. I highly recommend this meter.
Nice feature, you don't have to keep your finger on it.It also had it's own battery, I honestly thought I would have to buy new batteries, and I was wondering what kind it uses however it had NEW working batteries in it. Excellent.It wasn't broken, it was new, it was wrapped up well in a box and the instructions on how to use it was included.Sad to say NOTHING was wrong with anything.
The MP3 player showed a 1.5 mG reading (green) and the USB hub also received a 1.5 hit. I was unable to achieve any false readings with the electronic equipment in my house nor any readings at all in locations with no visible electronic equipment.As far as I can tell so far, it works exactly as advertised and feel confident that any readings I receive in the field will be accurate. The item is extremely light weight and runs off a 9 volt battery which was included.
this is very accurate & i justed used it yesterday night during a ghost hunt & we picked up EMF fields
this is a very sweet, easy to use product. it isn't for a techy who wants numbers and percentages. It has lights that are very east to see that indicate levels of radiation and that's all i wanted.
this is a great meter its very cost evefetive had for over a year now and only replace the batterys a few time
pros:lightweighteasy on/off button- user friendly..the lights are pretty.... (can you tell I'm really trying to find some pros for this thing?
boy this thing sniffs out EMF's like no ones business...I would highly recommend it to electricians and Ghost hunters alike.
bought this to go into my ghost hunting kit and it works great and lights are very bright. it easy to use on a hunt or just for construction of electrical things.
and have been enjoying it a lot. The first thing I did was see to what degree EMFs are coming from my various appliances, thus I was aghast by the nuclear bomb type of reading emitting from my microwave oven! The little bit of Internet research I've been doing has made it known to me that there's some concern with, among other things, people being subjected to significant amounts of EMF often developing forgetfulness.
Answer: yes
