The HSIN930-L ultra-low temperature dry block furnace sets a new benchmark for temperature calibration.
In the fields of industrial manufacturing, aerospace, scientific research, and defense industries, precise temperature calibration in extreme low-temperature environments has long been a challenging technical issue. Conventional dry block furnaces often face limitations in terms of temperature range, control accuracy, or operational efficiency, making it difficult to meet the demands for high-precision and high-efficiency calibration. Leveraging years of technological expertise, Beijing Hengsheng Weiye Technology Co., Ltd. has introduced the HSIN930-L ultra-low Temperature Dry Block furnace (operating range: -120°C to 80°C). Equipped with cutting-edge ultra-low temperature technology, an intelligent temperature control system, and a modular design, this product represents a significant advancement in the field of temperature calibration.
Key Features of the HSIN930-L:
Ultra-low Temperature Capability:
The device achieves a minimum temperature of -120°C, enabling accurate calibration under extreme conditions such as liquid nitrogen environments and cryogenic equipment testing.
High-speed Temperature Control:
The system can heat from -120°C to 80°C in just 30 minutes and cool from 23°C to -90°C in 50 minutes, and from -120°C in 90 minutes, significantly improving calibration efficiency.
Precision Performance:
The furnace offers full-range temperature accuracy of ±0.15°C and stability of ±0.01°C. The axial temperature uniformity across a 60mm length is ±0.088°C at 0°C and ±0.025°C at -120°C—substantially exceeding industry standards.
Intelligent Temperature Management:
The digital temperature control system supports rapid heating and cooling, with a display resolution of 0.01°C (adjustable), ensuring ease of operation and high efficiency.
Versatile Application Scenarios:
Designed for diverse applications, the HSIN930-L is suitable for use in industrial enterprises, research institutions, military sectors, and metrology laboratories. It supports the calibration of:
- Temperature sensors: thermocouples (Types S/K/E, etc.), platinum resistance (Pt100/Pt1000), and thermometers;
- Temperature transmitters/sensors: analog and digital output devices;
- Temperature switches and instruments: response time and threshold testing.
Modular Design Enhances Flexibility:
The interchangeable heat equalizing block comes standard with four bore sizes (Ø4/6/8/10 mm) and can be customized between 2 mm and 15 mm to accommodate various sensor types. Additionally, the system supports expandable measurement capabilities for multiple temperature sensing technologies, including thermal resistors, thermocouples, and thermistors.
Safety and Reliability:
Prioritizing user safety, the HSIN930-L integrates multiple protective mechanisms, including built-in safeguards against load short circuits, open circuits, and sensor anomalies, effectively preventing equipment damage. It operates reliably within environmental conditions of 0°C to 35°C, relative humidity <80% (non-condensing), and altitudes below 2000 meters, meeting the requirements of complex working environments.
With its breakthrough in achieving -120°C ultra-low temperature performance, millisecond-level temperature control precision, and comprehensive adaptability across application scenarios, the HSIN930-L redefines the capabilities of dry block furnace technology. Whether used in cryogenic equipment R&D, aerospace material testing, or large-scale industrial sensor calibration, the HSIN930-L delivers stable and reliable performance to support enterprise operations.
