Righty just one more question. Will I need a PPM meter to measure the carbon monoxide levels? Also, I'm not quite sure what EC is, I've seen people mentioning it. Any insight would be great :] I was looking at getting this, which doubles as a thermometer: http://www.ebay.co.uk/itm/UK-Qualit..._Measurement_Equipment_ET&hash=item3cadb40757
