Environmental Temperature Calibration Chamber

Equipped with a PID-controlled dual-stage refrigeration system and high-accuracy platinum resistance temperature sensors (PT100Ω, Class A), the chamber achieves steady-state equilibrium within minutes and maintains temperature drift below 0.1°C/hour. Standard volumes from 100L to 1000L provide flexibility for both small-scale sensor verification and large-scale multi-instrument calibration setups.

Unlike conventional environmental chambers, LIB Industry's Environmental Temperature Calibration Chamber models are specifically tuned for temperature uniformity, stability, and low thermal gradient performance, making them ideal for ISO/IEC 17025-compliant calibration laboratories and industries requiring traceable calibration accuracy down to ±0.05°C resolution.

Calibration is the foundation of accurate measurement and quality assurance. The temperature calibration chamber enables:

Sensor Accuracy Verification:

Quickly and precisely identify deviations across full operating temperature ranges.

Controller and Instrument Validation:

Test thermostats, data loggers, IC sensors, and industrial controllers under controlled thermal conditions.

Traceable Standards Compliance:

Ensure calibration aligns with IEC, ASTM, MIL-STD, and ISO/IEC 17025 requirements.

Accelerated Device Assessment:

Simulate long-term temperature exposure in hours, verifying performance stability over time.

By reproducing stable and repeatable environmental conditions, LIB Industry Environmental Temperature Calibration Chamber minimize error margins, ensuring devices perform reliably in production, field, or research environments.

Highlights of Controlled Temperature Chamber for Automotive

 

 

Stainless-Steel Workspace with Integrated Sensors

The inner workspace is made of SUS#304 stainless steel, ensuring durability and thermal consistency. Built-in PT100 temperature probes (±0.1°C) and digital humidity sensors (±1.5%RH) monitor real-time conditions, while the 360° air circulation system maintains uniform temperature (≤0.5°C deviation) for accurate multi-point calibration.

 

 

Airtight Sealing and Thermal Insulation

The temperature calibration chamber uses a multi-layer silicone gasket and high-density polyurethane insulation to achieve exceptional sealing and temperature stability. Door latches ensure leakage below 1.5% per hour, and a heated double-glass window prevents condensation for clear visibility during operation.

Reliable Cascade Refrigeration System

Dual-stage compressors (French TECUMSEH) with environmentally friendly refrigerants provide rapid cooling, minimal overshoot, and stable long-term operation for continuous calibration tasks.

User-Friendly Interface & Data Logging

Color LCD touch controller allows up to 120 programmable steps, real-time temperature graphing, USB data logging, LAN and PC-link connectivity for remote monitoring, and full traceability for compliance audits.
