L-Disk HT is a contact temperature data logger from -80°C to 140°C (calibration from -60°C to 140°C), with internal sensor, managed with Windows software and USB interface (DiskInterface HS, Multibay). The sensing point is located at the centre of the upper flat surface, for contact monitoring. There are two versions: with standard calibration from -60°C to 80°C, studied for lyophilization processes, and the HT version with standard calibration from -60°C to 140°C. Battery is user replaceable and the data logger is provided with an Accredia (NIST equivalent) traceable cetificate on 6 points. With calibration from -60°C it can be used also at -80°C with an accuracy within ± 0,5 °C within range -80 °C ÷ -60 °C. If -80°C is requested to be on the certificate, an extra calibration point for very low temperatures must be purchased.
2 tacky thermal pads (35 X 35 mm) to improve heat conductibility on rough surfaces are included.
There are also other models of very low temperature data loggers.
