E models combine our proven 21 and 31 series design and dimensions with precise digital PID microsprocessor temperature controller. This microprocessor with a J type thermocouple will hold set temperatures accurately within 1 degree with improved chamber uniformity.

Control features include large easy-to-read dual LED display, showing both set and process temperatures, select C or F units, autotune feature healps optimize PID parameters to balance oven faster temperature recovery times and processing of batch-style work loads not requiring accurate temperature stability.
