Designed for coating, composite, and heat‐curing industries, the PosiTest OTL captures both air and surface temperatures through K-type thermocouple ports. It includes bright LED status indicators, exportable CSV data, and a robust enclosure. XT kits further extend operational lifetime at high temperatures.
DeFelsko PosiTest OTL Oven Temperature Logger
With factory calibration and field durability, the PosiTest OTL simplifies oven profiling. Two AAA batteries power up to ~30 hours of logging. Probes (surface or air) are available with long stainless steel braided cables. Data is analyzed via PosiSoft desktop software with full batch & channel tagging.
