Variable temperature table(Cold and hot table) is an experimental device that can accurately control the ambient temperature of the sample and simulate precise temperature changes under different environmental conditions.
Variable temperature tableKey points for purchasing:
Temperature range and accuracy
Select the appropriate temperature range according to experimental requirements to ensure that the equipment can cover all testing conditions.
Prioritize selecting equipment with high temperature control accuracy (such as ± 0.1 ℃) to improve experimental reproducibility.
Temperature uniformity and fluctuation
Temperature uniformity refers to the consistency of temperature at various points within the working area, while fluctuation refers to the range of temperature fluctuations after stabilization. Choose equipment with good uniformity and low fluctuation to avoid local temperature differences affecting experimental results.
Box structure and sealing performance
The box shall be firm and durable, and high-quality insulation materials (such as polyurethane foam) shall be used to reduce heat loss.
Equipment with good sealing can prevent external air from entering, ensuring temperature control accuracy, especially suitable for vacuum or airtight environments.
Control System and Operating Interface
The control system should have PID regulation function, support programmed heating/cooling and multi-stage insulation.
The user-friendly interface supports touch screen or upper computer software control, making it easy to set parameters and monitor the experimental process.
Compatibility and scalability in combination
Select equipment that supports the combination of optics, electronics, or spectroscopy according to experimental requirements, and reserve interfaces for future expansion.
Optional auxiliary equipment such as vacuum pumps and gas flow meters can be provided to meet special experimental conditions.
Security and protection functions
The equipment should have functions such as over temperature protection, overload protection, and leakage protection to ensure safe operation.
The emergency stop button and fault alarm system can quickly respond to abnormal situations, avoiding equipment damage or personnel injury.
