The most important performance factor is precise and fast temperature regulation, which is best delivered by halogen lamps because of their low mass and therefore fast reaction time. This ensures repeatable results starting from the first measurement (some other heating sources either deliver different results in the first measurement or require a warm up measurement, which wastes time and resources). Furthermore, an even heat distribution on the sample surface is essential for repeatable and reliable results. We advise you to ask us or another manufacturer for a demonstration in order to experience the performance in real-life.
