faraday Posted October 29, 2020 Share Posted October 29, 2020 (edited) I want to be able to test the voltage from the plugs around the house, not only to see if they're safe, but also to know if they are delivering 240v, so it should incorporate a digital readout. I've seen voltage pens on Lazada, but have no idea if they're any good. Any suggestions please? Edited October 29, 2020 by faraday Glammar...

A voltage pen will not give a digital reading. the voltage in the MEA is a nominal 230V the voltage in the PEA is a nominal 220V neither the MEA nor the PEA maintains the nominal supply voltage, my PEA supply is at 224V at the moment it will change during the day. if in the Bangkok area you might see 240V once in a blue moon. Lazada has everything from cheap dangerous rubbish through copy goods to quality products, it is just an aggregator not a shop.

Oldie Posted October 29, 2020 Share Posted October 29, 2020 (edited) Perhaps buy something like this. Measures also the energy consumption. But look that it is for 220 Volt and not for 110. https://www.lazada.co.th/products/easygoingbuy-ac-power-meter-220v-digital-wattmeter-eu-energy-meter-watt-monitor-analyzer-i326278544.html Edited October 29, 2020 by Oldie 1 Link to comment Share on other sites More sharing options...
carlyai Posted October 29, 2020 Share Posted October 29, 2020 Probably better to go with a good solid reputable branded meter like a Fluke. Check Google and compare the range of Fluke meters. There may be other meters that do the job, but if you are just starting out measuring spooky stuff that can kill you, I'd stay away from cheap unprotected meters. 1 Link to comment Share on other sites More sharing options...

Popular Post lopburi3 Posted October 29, 2020 Popular Post Share Posted October 29, 2020 Agree a good multimeter should be great and no need to pay for a Fluke. I have this model which is fully automatic and very well insulated and wires are internal so no chance of short at connectors/meter and points are also very small and well protected. It has worked very well for me in the 2 or 3 years I have been using it. About 500 baht but a lot safer than the 1-200 baht models. https://www.lazada.co.th/products/huayi-ms8231-household-type-automatic-digital-multimeter-universal-meter-without-shifting-intelligent-anti-burning-high-precision-i1624098256-s4464030460.html? 1 2 Link to comment Share on other sites More sharing options...

Totally agree that any Fluke meter meter is total overkill for the OP's stated purpose of checking the AC voltage at the outlets of his home. This should do the trick, just select 600 V AC (one-click to the right) and when your finished turn it off (one-click back to the left). https://www.lazada.co.th/products/panda-home-xl830l-digital-lcd-multimeter-i245094416-s844982611.html Link to comment Share on other sites More sharing options...

Even with a Fluke, its recommended that you test it against an approved voltage source both before and after testing for dead. Link to comment Share on other sites More sharing options...
mogandave Posted October 29, 2020 Share Posted October 29, 2020 A multi-meter is great, but something like this might be better. I will test the ground, check that the hot and neutral aren’t switched, the voltage and test that your breaker will actually trip in the event of you getting shocked. 1 1 Link to comment Share on other sites More sharing options...

Problem is that its configured for UK sockets and not easy to use with an adaptor. Make sure its configured for Thai sockets. A very useful tool though. Only useful for testing sockets, it can't test any other circuits. Edited October 29, 2020 by polpott Link to comment Share on other sites More sharing options...

For normal use just turn on and take reading - AC/DC or Ohms with no need to change sockets on meter or observe polarity. Works every time and auto shut off and as said probes are very well insulated. 1 Link to comment Share on other sites More sharing options...
carlyai Posted October 29, 2020 Share Posted October 29, 2020 Yes I agree Fluke is an overkill. So my advice was over the top to someone just not quite up to my tally of electric shocks. (Luckily in my earlier days.) I'd go with what Crossy selects. Crossy' s shocks are probably 3 or less. Link to comment Share on other sites More sharing options...

faraday Posted October 29, 2020 Author Share Posted October 29, 2020 Just had a thought Crossy... Perhaps you could knock something like this up to use when moderating. Instead of a warning from you, the device could send a few volts to the troublesome member (tvf member I mean ) I'll most probably order the Habdotest one. Thanks. @Crossy Link to comment Share on other sites More sharing options...
bankruatsteve Posted October 29, 2020 Share Posted October 29, 2020 Using a DMM to measure voltage at a socket by "plugging in" the probes can be problematic if the probes are short or you just can't make good contact. Get the plug-in tester Crossy posted. Much simpler. 2 Link to comment Share on other sites More sharing options...

RichCor Posted October 29, 2020 Share Posted October 29, 2020 I'm still waiting for one of the ThaiVisa electrical experts to do a review on one of these Aneng AC11 plug-in analyzer/testers, but until that happens I'll probably order a Aneng AN9002 Bluetooth Digital Multimeter I've had an eye on. 1 Link to comment Share on other sites More sharing options...

carlyai Posted October 29, 2020 Share Posted October 29, 2020 The thing with these cheap readily available meters is, if you'ryou're fairly new to the game you could get a shock. Same with those neon pens that you have to put your thumb over. No way hozay for this little fella.

Charging up small paper capacitors with the insulation tester (500V DC) and then leaving them lying around for unsuspecting apprentices to "fetch for me please" was a favourite trick when I was an apprentice and later when I wasn't Health and Safety what's that? I also had some lengths of sleeving with crocodile clips on the end, hours of fun watching the poor lads trying to fault find their circuits. 2 Link to comment Share on other sites More sharing options...
