1. Large-Capacity Design & High Verification Efficiency
The 320L internal workspace allows for the simultaneous verification of multiple mechanical or digital thermo-hygrometers of various specifications. Equipped with dual access ports, the chamber enables direct adjustment of the instruments under test, significantly boosting verification efficiency.
2. Precise, Stable, and Reliable Temperature Control
It features built-in PID auto-tuning programs and a high-quality imported compressor, ensuring rapid stabilization and high consistency of the temperature and humidity fields to meet accuracy requirements across various test points.
3. Superior Sealing and Thermal Insulation
Utilizing double-layer, high-temperature resistant, and anti-aging silicone seals, along with an extra-thick insulation layer and vacuum-glass observation windows on three sides, the unit minimizes thermal loss. This ensures rapid and stable temperature ramping while isolating the internal test zone from external environmental fluctuations. Controllable internal lighting is also included to facilitate verification operations.
4. Compliance with Metrological Standards
Technical specifications fully comply with standards such as JJF1564-2016 (Calibration Specification for Temperature and Humidity Standard Chambers), JJG 205-2005 (Verification Regulation for Mechanical Thermo-hygrometers), and JJF1076-2020 (Calibration Specification for Digital Thermo-hygrometers), making it suitable for compliant verification tasks across all levels of metrology departments.
5. Optimized Ease of Use
Features an intuitive touchscreen interface and supports one-touch data export, simplifying the archiving of verification records and report generation.
Equipped with heavy-duty swivel casters for easy positioning; the unit can be quickly leveled after relocation to ensure temperature and humidity uniformity within the chamber.
6. Comprehensive Safety Protection
Includes protections against over-temperature, compressor overload, electrical leakage, and high/low pressure. The system automatically shuts down and triggers an alarm in the event of a fault, ensuring the safety of both equipment and personnel.
