High-Low Temperature Test Chamber LTTC-C20 Catalog
Labtron Temperature Test Chambers are designed for controlled environmental testing across industrial and research applications. They feature a balanced temperature control system, ensuring uniform heating and cooling for stable performance. These chambers have SUS304 stainless steel interiors with advanced insulation to enhance efficiency and durability. Their programmable touchscreen controller allows easy operation with multiple communication interfaces for smooth data transfer. Our Temperature Test Chambers are ideal for reliability testing, material evaluation, and electronic component assessments.








Yes, remote access and monitoring are supported through Ethernet or USB connectivity. Users can control the chamber, adjust parameters, and view real-time performance remotely. Alarms and notifications can be sent via email or system alerts, improving operational safety. This feature is especially useful in long-duration or unattended testing scenarios. Software compatibility enables integration into central lab management systems. Password-protected access ensures data security and authorized usage only. Remote diagnostics can also aid in troubleshooting and maintenance.
The High-Low Temperature Test Chamber LTTC-C20 employs a cascade or single-stage refrigeration system depending on the temperature range. It uses environmentally friendly refrigerants that comply with current global regulations. High-efficiency compressors and expansion valves are optimized for stable cooling cycles. The system is engineered for quick pull-down rates and long-term reliability. Advanced temperature control reduces compressor stress and extends operational life. Thermal load compensation ensures the system adjusts to sample mass. Condensation control prevents frosting, even in continuous low-temperature use.
Multiple safety features are integrated to protect both users and samples. These include over-temperature cut-off, circuit breaker protection, and emergency stop functionality. The door is equipped with safety locks to prevent accidental opening during active cycles. Interior lighting and observation windows allow monitoring without interrupting the test. Electrical systems are grounded and conform to international safety standards. Alerts for abnormal conditions are displayed on the screen and logged. Maintenance access panels are clearly marked and secured.
The High-Low Temperature Test Chamber LTTC-C20 is primarily designed to perform optimally in ambient conditions ranging from +5? to +35?. For high-altitude labs or extreme environments, system tuning may be necessary. Performance at lower atmospheric pressure may affect heat exchange efficiency. Users should consult Labtron for site-specific adjustments like reinforced insulation or upgraded compressors. Internal sensors adjust for minor ambient fluctuations to maintain accuracy. Installing the chamber in climate-controlled spaces is recommended for stable output. Operating manuals include guidelines for installation in challenging locations.
The High-Low Temperature Test Chamber LTTC-C20 uses strategically placed circulation fans to distribute air evenly throughout the chamber. This ensures consistent temperature exposure, regardless of sample placement. Advanced sensors monitor temperature gradients and adjust airflow in real-time. The chamber’s interior geometry is designed to minimize hot or cold spots. Thermal mapping can be performed for validation using multiple sensor points. Uniformity is typically within ±2.0°C, meeting industry standards. This precision is essential for reliable and repeatable testing outcomes.
