Stand-alone data logger with an LCD display and four external input channels. The TLL has compatible proprietary sensors for temperature and AC current and the logger can also be used with non-proprietary sensors that have low voltage DC or 4-20 mA output. In addition to fixed interval logging, this logger supports burst logging and can report minimum, maximum, average, and standard deviation statistics. The logger can hold up to 1.9 million measurements in memory. The user can also program the logger to produce an alarm when the sensor exceeds a set threshold. With 16-bit resolution, the accuracy of this logger is twice the accuracy of previous models of HOBO loggers.
