The ThermoVault is a thermally insu-lated, battery powered, stand alone, thermocouple based temperature data logger used for the thermal profiling of ovens. The device records temperature data inside an oven to be later down-loaded from to the user’s PC. The ThermoVault will measure and record up to 500,000 measurements per channel. It can withstand an oven temperature of up to 300 °C (572 °F) for up to 36 minutes when properly sealed. The devices real time clock ensures that all data is time and date stamped. The storage medium is non-volatile solid state memory, providing maximum data security even if the battery becomes discharged. The device can be started and stopped directly from your computer and its small size allows it to fit almost anywhere. The ThermoVault makes data retrieval quick and easy. Simply plug it into an empty USB port and our user-friendly software does the rest.
