Rotronic Instruments TL-1D Регистратор данных

The Rotronic TL-1D is an economical and compact (90 x 60 x 23 mm) data logger which can log up to 32,000 temperature-measured values in a range from -20 to +70 °C (± 0.3 °C). All measurement values are stored within the instrument for download via the HW4 software, which enables graphical display of values and instrument functions such as the logging interval, logging mode and alarms. On the face of the instrument, the right LED flashes green every 5 seconds during data logging and the left LED flashes red every 5 seconds when values exceed/drop below the alarm settings or when the battery is low.
