Recommendations for an infrared thermometer
Does the following eBay item look satisfactory for balancing domestic
central heating radiators? http://tinyurl.com/y4olvf The nearest alternative is the following but would be over 40 quid with postage. http://cpc.farnell.com/jsp/endecaSea...sp?sku=IN02293 Details of any alternatives appreciated. |

Emissivity of radiators (or black pvc tape on pipes) is pretty good. An IR thermometer makes short work of measuring temperature drop over radiators. Doing the same with contact thermometers takes an age and a half. Measuring bare copper pipe is not accurate but adding a half inch square of black tape makes all the difference. -- Agreed |

Slurp It isn't infrared which is what the FAQ recommends, plus the use of black tape. I want to do it once and do it right and I don't want to spend cheap then pay double. |
