Labtron offers temperature and humidity test chambers with capacities ranging from 50 to 1130 L. They have a humidity controller and thermal-insulating material resistant to high temperatures. They feature an LCD touch screen with a corrosion-resistant interior chamber and a double-layered glass observation window. They include an independent R&D software and a compressor overload switch. Our temperature and humidity tester has built-in safety self-protection and overheating prevention.








The built-in data logger in the Temperature and Humidity Test Chamber LTHC-I12 allows automatic recording of temperature, humidity, and test cycle data over extended periods without manual intervention. This data can be easily exported in CSV format, enabling users to conduct detailed post-test analysis, maintain regulatory compliance, and generate accurate reports for quality assurance and certification purposes. The logger supports high-resolution time-stamped entries that are essential for traceability and long-term archiving in R&D and production environments.
The Temperature and Humidity Test Chamber LTHC-I12 features an intelligent energy-saving system that includes automatic compressor shutdown during stable test conditions, significantly reducing power consumption. This not only extends the lifespan of the compressor but also lowers electricity costs, especially during long-duration or continuous testing. Additionally, its thermal insulation and optimized airflow design help maintain consistent environmental conditions while minimizing energy loss, making the unit both eco-friendly and cost-effective for daily laboratory or industrial use.
The Temperature and Humidity Test Chamber LTHC-I12 is engineered to perform stress tests such as accelerated aging, thermal cycling, and high-humidity exposure with high accuracy. These capabilities simulate extreme environmental conditions to reveal potential material weaknesses or failure points in products. As a result, it supports high-reliability validation for electronics, medical devices, aerospace components, and automotive parts by ensuring that the products meet or exceed durability expectations before they reach the market.
Uniformity is maintained through a multi-directional airflow system that evenly circulates conditioned air across all chamber zones. The use of precision sensors and PID-controlled heating and humidifying elements ensures that the internal environment stays consistent, with minimal deviation from set values. This prevents localized hotspots or humidity pockets, ensuring that all samples, regardless of their placement, experience the same test conditions critical for accurate and repeatable results.
The Temperature and Humidity Test Chamber LTHC-I12 is equipped with a user-friendly digital touchscreen interface that simplifies test programming, parameter monitoring, and data export. It supports real-time display of temperature, humidity, and run time, while also allowing users to set multi-step test profiles with varying conditions. Built-in alarms and intuitive menu navigation make it easy for both experienced technicians and first-time users to operate the chamber confidently and safely, even in complex testing workflows.
