The Ultra Low Temperature – Environmental Chamber by Jeiotech is a reliable tool for precise environmental testing across a range of scientific applications. Offered by Apex Scientific in South Africa, this chamber delivers a broad temperature range from -70 °C to 150 °C and maintains humidity between 25% and 95% RH. As a result, it supports critical experiments with consistent performance.
The graph illustrates the operating range of the TH-KH Environmental Chamber. The yellow area shows the conditions under which the chamber maintains stable temperature and humidity control—specifically between approximately 30 °C and 90 °C, with relative humidity ranging from 30% to 95% RH. The hatched section on the left side indicates that continuous operation below 30 °C is not recommended for periods exceeding 24 hours. This visual guide helps users understand the chamber’s performance limitations and ensures optimal use for long-term environmental testing in various research and industrial applications.
Performance
This unit features PID microprocessor control, enabling accurate temperature calibration and automatic tuning. Moreover, its built-in humidification tank is optimally placed to support stable conditions during extended tests. A water recycling and filtering system helps reduce overall water use, promoting efficiency over time.
The air-tight door closure includes heat-resistant silicone packing to prevent thermal leakage. Additionally, a two-point latch reinforces the seal for improved energy efficiency. Even when operating at maximum temperature, the outer surface stays safely below 60 °C.
Safety Features
Safety has been prioritized throughout the design. For instance, a key-lockable door prevents unauthorized access. The system also shuts down automatically if temperatures exceed limits and includes alerts for low or empty water levels. Furthermore, overcurrent protection, leakage breakers, and an open-door alarm ensure safer operation.
Convenience and Usability
Available in three size options, this chamber accommodates diverse laboratory workflows. It includes a corrosion-resistant stainless steel interior and an electric-polished humidification tank for long-term durability. In addition, the front water tank and portable refill container simplify regular maintenance. If needed, an optional direct water system supports continuous operation.
Monitoring your samples is straightforward thanks to a tempered glass door with built-in heating wire and LED lighting. An internal glass door is also included to enhance visibility. The standard 50 mm cable port supports external sensors, and larger ports are available upon request.
For easier mobility, the unit comes with casters for transport and setup. The integrated 5.7-inch LCD touchscreen controller displays current and target values in real-time. You can also visualize data through graphs, log results using the SD card slot, and operate in your preferred language with trilingual support (English, Chinese, Korean).
