About Me Why should you believe a word I have to say? Atty Test Results All testing was performed while actually vaping the fully assembled atty, i.e. under real life conditions! How to measure the temperature on your own atty. Formaldehyde Levels in a real atty under real conditions...

Someone asked me a question in a PM and I decided to post the answer here as others may be interested. Many "Multimeters" come with banana jacks that will also accept a "Type K" thermocouple. If you have a thermocouple setting on your multimeter this is a solution you can do at home cheaply. It...

First read this article from vaping360.com, which is a very good article to read ENTIRELY! The TC Mods I use are calibrated, and validated, with NIST traceable instruments to be +/- 10 degrees, but just because mine are accurate doesnt mean they all are. There are a lot factors that must come...

What got all of this started was a thread I started here on ECF (after being goaded by a certain Admin paybacks are hell). I had discovered some new research by Wang and Guiss suggesting that carcinogens (like formaldehyde) start getting produced at high temperatures, temperatures that were...

I have discovered I am a wimp! I thought I was hardcore running 36mg on dual coils and clapton coils etc, MTL. But I have to admit, 2mg DTL on this high wattage beast just kicks my ..... I wont be testing any more of these, DTL is not my thing. My first attempt at testing this I just did MtL...

Penguin SE This is a refillable "Pod Mod". Comes with 2 different "Atopack" coils,, a 0.25 ohm for DTL and 0.6 ohm for MtL. It is a direct output mod, ie it is like a mech, no regulation. There is no airflow adjustment and MtL is a little too airy, but it is easily modded to restrict...

Test results: One thing I failed to record was that the stock coils were on the newer "vertical" style coil, not the original horizontal coils. Looks like above 3.9v on VV, or 7.5W on VW, started getting a little warm with respect to the claims made in the Wang Study. Using the largest...

Ok, so Photosucket screwed us. Here is one way you can fix your Blogs, and any other posts that you can still edit. You can easily run your own private image hosting app that is even more powerful than Photobucket, and a heck of a lot faster, with no Ads. You can even set it up for a group of...

@homeuser6 sent me an RSST genny with a 2.08ohm kanthal coil, wrapped around 3mm Ekowool. He vapes on a mech so he asked me to measure that set of parameters. juice was about 85/15 VG/DW. Note that this was a "modded" top cap and had four 1mm airholes. This made a huge difference as when I...

iClear 16 Thanks to @Mazinny I had a bunch of iClear16s to test. Stock dual coil 2.1 ohm VV tested on a Provari VW tested ona Vamo 40/40/10 PG/VG/Flavoring used, 36mgml Standard NIST traceable Thermocouple test bench Was tricky to insert probe, inserted probe on top of bottom coil: Used a...

OK, so the Protank 2 coils were a real PITA to test. The 40gauge thermocouples are tiny, delicate, and they fell out easily and frequently. So I got a chance to see and feel the wicks a lot while re-threading the probe. There is no doubt, the rebuilt coils with cotton held magnitudes more juice...

Please read through this blog, then you decide if you should trust my credibility or not. I have nothing to gain or loose either way..... My name is Mike Petro, I am 59 years young. I smoked for 40years+, the last 10 years I smoked 5-7 large 50 ring gauge cigars a day, and inhaled every last...

Context: The RCP announcement got widely publicized as meaning that vaping was 95% safer than smoking, however the detail and context of the entire report has not been talked about nearly as much. From the Royal College of Physicians, 11 St Andrews Place, Regent's Park, London NW1 4LE...

Note: the context of this entry is trying to increase the understanding of VV and VW coil temperatures. Studies by Wang and Guiss suggest that carcinogens (like formaldehyde) start getting produced at high temperatures. I have proven, in some of my other blog posts, that our coils can indeed...

Note: the context of this test was in trying to understand why Dr Kurt @Kurt found so many carcinogens in Gen 2 devices, and hardly any in Gen 3 devices. Most Gen 2 devices used silica in a top coil configuration, where Gen 3 introduced cotton, and other materials, in bottom coil configurations...

As promised, a follow up to the wick test. The last test was mainly to show how poor silica is compared to modern wicking materials. The context being that poor silica performance might have significantly contributed to why Dr Kurt's Gen 2 results detected so much formaldehyde. On this test I...

First, you will notice a different format than my previous tests. Today's test represents about 9 solid hours of testing, it takes time to figure out how to insert the tiny probes in those tiny cartridges, and still be able to actually vape the device, lots of trial and error. Anyway, it would...

Theory My theory is that by reducing the boiling point of your ejuice, you can reduce the atty temperature needed to achieve a satisfying vape. I.e. keeping under 410f we can avoid the carcinogens that were proposed by the Wang Study. This could potentially help VW mod users as well...

OK, as promised I ran some tests using a thermocouple on a Merlin RTA to get some real life temperature measurements inside of a modern atty under real use. I threaded a .010" thermocouple (click link for source) through the airhole up into the chamber I tucked just the end up underneath...
