XIAMENFour-Zone Constant Temperature Environmental Test Chamber for Coin Cell Testing
SPECIFICATIONS
Overview
The TOB-25L-5V100mA-16CH-4 is a laboratory-grade environmental testing system engineered for high-precision thermal evaluation and electrochemical cycling of coin cells.
The system integrates four independent constant-temperature zones, multi-channel milliamp-level charge–discharge capability, and PID-regulated semiconductor thermal control, enabling stable and repeatable battery characterization under controlled environmental conditions.
Designed for battery R&D laboratories, universities, and pilot-scale validation facilities, this equipment supports simultaneous multi-sample testing, improves experimental throughput, and ensures reliable thermal uniformity and safety compliance.
Key Product Features
● Four Independent Temperature Zones
● Four fully isolated chambers, each with 25 L internal volume
● Independent thermal regulation for parallel multi-condition testing
● Total capacity of 64 coin cell test positions
This architecture enables comparative studies, batch validation, and accelerated screening within a single compact platform.
Integrated Charge–Discharge Testing Capability
● Up to 16 channels per temperature zone
● 64 total milliamp-level channels across the system
● Compatible with 5 V / 100 mA precision testing modules
● Ethernet communication for upper-computer programming and control
The chamber functions as a combined environmental simulator and electrochemical tester, reducing laboratory footprint and simplifying system integration.
High-Stability Thermal Performance
● Temperature range: 15 °C to 60°C
● Temperature fluctuation: ≤ ±0.5°C (no load, stable state)
● Temperature deviation: ±2.0°C
● Heating time: 25 °C→60°C≤50 min
● Cooling time: 25 °C→15°C≤60 min
Thermal regulation is achieved through PID-controlled semiconductor cooling and heating modules with forced air circulation, ensuring uniform temperature distribution and repeatable test conditions.
