Product Details
Detailed Introduction & Technical Features
Fully understand the core performance, structural design, technical advantages and application scenarios of this product to provide you with a professional selection reference.
Product Name
Low temperature test chamber / low temperature constant temperature test chamber / low temperature test machine
Application
This equipment is suitable for testing the performance indicators of products under low-temperature environments.
Chamber Structure
- Overall forming: the chamber body is CNC-machined with an attractive, generous appearance, and uses non-reactive handles for easy operation.
- Inner chamber material: imported high-grade stainless steel (SUS304) mirror plate; the outer shell is A3 steel plate with powder coating, enhancing the appearance and cleanliness.
- Observation window: a large observation window with lighting keeps the chamber interior bright, and laminated tempered glass with embedded heating elements allows clear observation of the chamber interior at any time.
- Test port: a Ø50mm test port on the left side of the chamber for external test power supply or signal cables.
Control System
- Temperature instrument: temperature control uses a fully imported touch-key instrument; operation and setting are simple.
- Lock function: after data and test conditions are entered, the controller has a lock function to prevent temperature values from being changed by unintended touching.
- PID auto-tuning: the PID auto-tuning function instantly corrects temperature change conditions, making temperature control more precise and stable.
- Options: a printer is available as an option.
Refrigeration System
The refrigerator of the low temperature test chamber uses original French “Tecumseh” fully hermetic compressors. The refrigeration system adopts a single-unit or binary low-temperature circuit design. A multi-blade blower provides strong air circulation, avoiding any dead zone and ensuring uniform temperature distribution in the test area. The supply and return air path design meets test standards for air pressure and velocity, with fast temperature recovery when the door is opened. The heating and cooling systems are fully independent, improving efficiency, reducing test cost, extending service life and lowering the failure rate.
Standards
