Low Temperature Constant Temperature Circulating Bath

The high-precision cryogenic temperature-controlled circulating bath combines refrigeration and heating capabilities, employing a PID precision temperature control system that delivers exceptional accuracy and stability. It provides users with a thermally uniform environment for experiments, finding extensive application in research departments across petroleum, chemical engineering, electronic instrumentation, physics, chemistry, and bioengineering, pharmaceuticals and healthcare, life sciences, light industry and food processing, physical property testing, and chemical analysis. It serves research departments, higher education institutions, enterprise quality control, and production units by providing a controlled thermal environment with uniform, constant temperatures. This enables users to conduct constant-temperature experiments or tests on samples or products. The unit may also function as a primary or auxiliary heating/cooling source.
