Small Laboratory Benchtop Environmental Test Chamber

The Small Laboratory Benchtop Environmental Test Chamber provides comprehensive temperature and humidity control within a compact, ultra-quiet design. It offers full functionality, supporting three low-temperature options: -20°C, -40°C, and -70°C, as well as a high temperature of up to +150°C. Humidity can be precisely controlled from 20% (or 10%) RH up to 98% RH. Additionally, the chamber allows temperature change rates of 1°C/min, 2°C/min, 5°C/min, and even higher.

1.  Ultra-Quiet Operation: The Benchtop Environmental Chamber operates at or below 60 dBA, quieter than a standard office printer. This ultra-low noise ensures minimal disruption to sensitive experiments, team discussions, or video conferences, even during intensive temperature and humidity cycles. Its whisper-quiet design makes it ideal for laboratories, research facilities, and cleanrooms, where a disturbance-free environment is crucial for accurate measurements and consistent testing results.

2. Space-Saving Benchtop Design: With compact dimensions of 820 × 1160 × 950 mm, the small benchtop environmental test chamberTH50 fits easily beside a workbench or under a fume hood. This space-efficient design allows laboratories to maximize floor space without compromising on functionality. Despite its small footprint, the chamber delivers full-scale environmental testing capabilities, making it a practical choice for both academic and industrial applications.

3. Comprehensive Temperature & Humidity Control: The small benchtop test chamber can simulate nearly any environmental condition, covering –86 °C to +150 °C and 10 %–98 % RH. Its robust compressor-based cooling system combined with electric heating elements allows testing across extreme cold storage, tropical climates, and everything in between. This versatility makes it suitable for electronics, materials, and battery testing, providing reliable data under real-world conditions.

4. Rock-Solid Precision & Uniformity: Equipped with high-accuracy PT100 Class A sensors delivering 0.001 °C resolution, the benchtop environmental chamber ensures precise temperature and humidity control. Advanced PID algorithms maintain temperature within ±0.5 °C and humidity within ±2 % RH, while centrifugal fans eliminate gradients. All samples experience uniform environmental exposure, guaranteeing repeatable and dependable results for research and quality control.

5. Rapid Cycle Times: Accelerate testing with cooling rates of 1 °C/min and heating rates of 3 °C/min. Preloaded programs allow hundreds of sequential steps in a single profile, significantly reducing setup time. Fast cycle capabilities increase testing throughput, improve efficiency, and help laboratories quickly collect and analyze critical data.

6. Durability and Safety: The interior is constructed from corrosion-resistant SUS304 stainless steel, maintaining structural strength under high humidity. The exterior 4 mm A3 steel frame with powder coating ensures industrial-grade durability. Safety systems, including leakage current protection, grounding, phase monitoring, and over-temperature shutdown, protect both operators and equipment during demanding testing cycles.

Product Operate Guide

The operation of the benchtop environmental chamber requires careful attention to ensure accurate and reliable test results. Before starting, turn on the main power and verify all connections. Set the desired temperature, humidity, and ramp rates on the touchscreen controller. Load samples evenly, avoiding contact with chamber walls. During testing, monitor temperature and humidity continuously, ensuring they remain within programmed limits. After each cycle, clean the chamber interior and remove any spills. Regular checks and proper handling improve performance, maintain equipment longevity, and ensure operator safety.

FAQ

Q1. Does Benchtop Environmental Test Chamber have automatic water inlet?

A: The benchtop  Environmental Test Chamber is not equipped with an automatic water inlet. The water tank is located at the top of the chamber and uses a manual water filling design to prevent overflow. This ensures both operational safety and long-term stable operation of the equipment.

Q2: Can Small Environmental Test Chamber achieve 5 °C/min (or 10 °C/min) fast temperature change?

A:Of course! Although the benchtop device has a compact design, its performance parameters are consistent with those of larger equipment. We support various non-standard customizations, including rapid temperature ramp rates, to meet your specific requirements.

Q3: Can curves be drawn during Benchtop Environmental Test Chamber test process?

A: Of course. The LIB controller includes the curve plotting function as a standard feature. During the Benchtop Environmental Test Chamber test process, it can generate and display curves in real time, making data changes clear at a glance. The device automatically records data every minute to ensure complete and reliable information. The system supports uninterrupted records for up to three years. After three years, the earliest data will be automatically cleared to continuously save new records, providing your tests with long-term, stable, and traceable data support.
