In combination with the needs of domestic scientific research users, various practical functions have been developed.
  • Overview
  • Specifications
  • Parameter

The TC290 temperature controller, based on the previous generation TC280 series, adopts various advanced technologies and is further upgraded and optimized. It has extremely high resolution, accuracy, and stability, and is at the forefront of the industry. It can support resistance sensors with diodes, thermocouples, platinum resistors, and negative temperature coefficients, and can connect up to ten temperature sensors to achieve the experimental purpose of multi-point testing. Simultaneously equipped with multiple communication methods such as Ethernet, RS-485, and USB, the data transmission distance is long, and data collection is convenient and flexible. The sensor adopts a balanced output dual constant current source method, which can automatically shift gears at extremely low temperatures, reducing the injection energy of the sensor and ensuring stable and reliable operation of the sensor.

TC290 has two control loops at the same time, and the input of each loop can be associated with any one of the ten sensors. It can be extended to two 100W or one 200W low-noise heaters at most, and can achieve closed-loop temperature control in multiple modes. It also has self-tuning function, making operation simpler and faster.
