Product Functions
TEC207/215 is primarily used for temperature measurement and control in large sample chambers.
Product Features
- Temperature measurement sensitivity: 0.1 mK, long-term temperature measurement drift (24h): <1 mK.
- Temperature control stability: ±0.001~0.01°C (dependent on the controlled object and parameters), suitable for most scenarios, including the stringent temperature control requirements of semiconductor lasers.
- Bipolar or unipolar output options available.
- Capable of limiting the maximum rate of temperature change.
- Supports thermistor temperature sensors (NTC).
- Capable of high-power output (maximum support for single channel 24V 15A).
- Features overheat protection for the circuit board, reliable performance.
- Allows direct parameter setting via the display control module, with data retention upon power loss, facilitating production by operators.
