“We recently had one large pharmaceutical customer who had experienced some issues with a non-Vaisala thermal validation system. The company had concerns with the accuracy of the devices and quality of the calibrations and documentation. They made an internal decision to use only Vaisala data loggers for thermal validation.”
“Over a 12-month period we could typically use a given DL-series logger for at least a dozen different projects for various clients in different locations and applications throughout the country. Depending on the year, we might do up to 20 or more validation projects between annual calibrations. Despite heavy usage, we rarely see temperature sensor failures.”
