For extremely high surface temperatures, the non contact measuring principle is not always good enough. Our VVHT versions are the answer to otherwise impossible applications, like level measurement on highly alloyed steels and precious metals. These very specialized versions are available in the following families: ODS Grey-Line, ODS Black-Line & ODS Red-Line sensors and O2DS Z-Line scanners. Based on a BLUE laser diode the VVHT versions are capable of measuring on extreme hot target surfaces up to 2.200ºC.
