        TADT portable humidity generator is a portable and high-precision temperature and humidity calibration instrument, which can meet the needs of measurement and calibration of conventional temperature and humidity measuring instruments such as temperature and humidity sensors, temperature and humidity transmitters, small temperature and humidity meters, etc.

        ?The test chamber space is (2~4) times that of the same product, and the test chamber of the same product is (2~4) L, this model standard test chamber volume 8 L, can be customized for customers alone extended test chamber volume can reach 12 L;

        ?The test chamber can accommodate various types of input cold mirror dew point probe, which is convenient for comparison and calibration;

        ?Combined sensor jack design, can be adapted to various diameter temperature and humidity sensors and transmitters;

        ?Can be calibrated at the same time (10~15) only small temperature and humidity probe;

        ?The test chamber provides temperature uniformity within 0.1℃ in the range of 5℃~50;

        ?External drying cylinder design, desiccant replacement in the state of on-line operation, convenient and simple;

        ?Two-zone drying cylinder design, supporting both molecular sieve and discoloration silica gel desiccant;

        ?Visual liquid level and dryer state display, conducive to the working process of state monitoring;

        ?The instrument has built-in humidity conversion software, which is convenient for users to convert relative humidity, temperature and dew point temperature;

        ?Support temperature and humidity curve display, easy for users to view the temperature and humidity state trend;

        ?7-inch color LCD touchscreen
