FEATURES OF MODEL 21-350E
Combines our proven 21 and 31 series design and dimensions with a precise digital PID microprocessor 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 helps optimize PID parameters to balance oven performance for various work loads and applications. A versatile on/off control mode allows for even faster temperature recovery times and processing of batch-style work loads not requiring accurate temperature stability.
