DTK Precision Temperature Controller is mainly used for the transformation of the temperature control method of the old oil tank, water tank, and thermocouple verification furnace. It can accurately control the temperature of one or more constant temperature devices. The imported intelligent temperature control meter is used, and its temperature control index meets JJF1637-2017, "JJG229-2010", "JJG141-2013", "JJG75-1995", "JJG668-1997", "JJG368-2000" and other technical requirements.
