We are proud to announce a significant technological advancement in ultra-low temperature calibration technology.

Our newly developed -120°C Dry Block Calibrator now achieves a groundbreaking performance:

This level of precision at such an extreme low temperature is a world-leading achievement for a dry block design – no liquid medium required, ensuring safety, ease of use, and zero contamination risk.

Key Advantages

• Completely dry operation – no fluids, no mess, no maintenance
• Compact and portable for both laboratory and on-site calibration
• Intelligent touchscreen interface with automatic stability judgment and real-time data display
• Supports multi-point correction and full traceability to national standards

Primary Application Scenarios

1. Low-Temperature Sensor Calibration Ideal for calibrating Type T/E/N thermocouples, low-temperature PRTs (Pt100/PT1000), and NTC thermistors in extreme cold conditions.
2. Cold Chain & Vaccine Storage Validation Ensures accuracy of temperature loggers and sensors used in ultra-low freezers (-80°C to -120°C) for vaccines, biologics, and pharmaceuticals.
3. Aerospace & Defense Testing Simulates cryogenic environments for temperature sensors in aircraft, satellites, and missiles.
4. Scientific Research & National Metrology Supports reference-grade calibration in national institutes and research labs requiring extreme low-temperature standards.
5. Industrial Process Control Verifies sensors in LNG (liquefied natural gas) systems and deep-freeze industrial applications.

This breakthrough reinforces DEARTO's commitment to innovation in metrology and calibration. We invite laboratories, calibration centers, and industrial partners worldwide to experience the performance of our -120°C Dry Block Calibrator.
