<div dir="ltr"><div>Second is a Crowcon personal gas monitor. Once you've activated it, it only lasts for 2 years, then switches itself off. But, its really good. Seems super accurate and you cant possibly mess anything up its all automatic. Tells you when to calibrate it etc. Also its small enough to clip to your belt, and not too expensive. This is the best one i have and i will get another when this runs out. You can see it is telling me it has 10 months left to run. Crowcon make another called "gasman" i think which may be slightly better, i will check that one out for next time as well. I have a feeling it can be re-used. </div><div> </div><div><img width="368" height="490" src="cid:ii_i2yr4m000_149ec5fac372c4c0"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 26 November 2014 at 13:48, James Frankland <span dir="ltr"><<a href="mailto:jamesf@guernseysubmarine.com" target="_blank">jamesf@guernseysubmarine.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hi Hank,</div><div>I've got 3. The first i got was the "el cheapo" which you assemble yourself. I find this the worst of the 3 as its very sensitive and seems to be a bit all over the place.
