measuring temperature / thermometers see also: * infrared thermometers * thermometers * I don't sell any of these nor do I receive any remuneration if you buy them, and I have not personally reviewed all of them, they are listed here to give you perspective Introduction * measuring the temperature seems easy but it can be quite complex depending upon what is being measured and how accurate and timely one needs the measurement
