Torontech Benchtop Environmental Chamber: Compact Precision for Temperature and Humidity Testing

A benchtop environmental chamber blends compact size with advanced functionality, enabling rigorous temperature and humidity testing on small samples without occupying heavy lab space.

Torontech’s 15L/30L/50L series delivers dependable performance across a wide range—from –70 °C to +150 °C—with optional humidity control available. Curious about how this benchtop solution could enhance your lab’s capabilities?

Let’s explore its design, features, and real-world applications.

Rugged Construction for Reliable Performance

This benchtop thermal chamber is engineered with strength and precision in mind. The interior employs 1.5 mm SUS304 stainless steel, mirror-finished and TIG-welded to ensure a durable, leak-proof space.

Externally, cold-rolled steel with a rust-resistant electrostatic coating safeguards the chamber. Enhanced insulation features 80 mm of composite polyurethane foam and ultra-fine glass cotton, maintaining steady internal temperatures during rapid cycling.

The door is sealed with temperature-resistant silicone strips and built-in heating wires to prevent frost and condensation. Ideal for low-temperature testing scenarios.

Optimized Viewing and Sample Handling

Using a benchtop humidity chamber means you can monitor test specimens without opening the door. A multi-layer tempered anti-fog viewing window (178×200 mm) remains clear thanks to integrated defrost heating.

Internal LED lighting can be toggled via the touch screen, offering visibility without affecting internal temperature or humidity. A Φ50 mm cable port allows introduction of external sensors. Dual-layer sample holders with adjustable heights accommodate various test configurations, ensuring secure and adaptable placement.

Precision Temperature and Humidity Control

This chamber’s core strength lies in refined environmental regulation. The system ensures consistent airflow using a stainless-steel centrifugal fan. A combination of PID-controlled finned heating elements and a German Secop compressor with an air-cooled evaporator provide rapid and even temperature changes.

When humidity control is required, the temperature humidity chamber integrates:

• Electric steam humidification via SSR control
• Freeze-cycle dehumidification
• A self-priming water pump and float switch for automation

These systems maintain stable climate conditions—crucial for replicable and valid test data.

Advanced Digital Interface and Programming

Control is simple and versatile with the Siemens PLC and 7-inch color touchscreen onboard. You can choose between manual operation or automatic sequencing with up to 20 pre-set programs featuring 99 segments each.

The display updates in real time on temperature, humidity, heating and cooling outputs, elapsed time, and cycle progress. Optional PC connectivity enables remote monitoring, data logging, and report generation—key for labs prioritizing traceability. Password-protected access and user role segmentation safeguard your test runs.

Safety First with Comprehensive Protection

Long-duration tests are more manageable with robust safety systems in place. The chamber includes safeguards for compressor overpressure, overload, refrigerant leaks, power phase imbalances, and electrical anomalies.

Overheat protection, screen lockouts to avoid accidental control interference, and backup temperature safety systems further reduce risk. Visual and audible alarms are triggered if faults occur, and every event is logged for audit purposes.

This makes the benchtop environmental chamber suitable for regulated environments where documentation and reliability are crucial.

Real-World Use Across Industries

These benchtop test chambers find application in multiple sectors:

1. Aviation and aerospace: Thermal cycling of sensors, adhesive bonds, and micro-electronics
2. Automotive: Reliability testing of connector boxes, seals, and circuit boards
3. Medical and pharmaceuticals: Validation under temperature stress or humidity-induced degradation
4. Telecom and electronics: Qualification of PCBs, components, and flexible circuits during thermal and humidity cycling

Whether you run quick ramp tests or prolonged dwell cycles, the chamber offers flexibility to suit your protocols.

Installation and Routine Maintenance

Setting up the chamber is straightforward, ideal for most lab environments (0–35 °C, 5–95 % RH). Its compact design includes a top-mounted cooling system to minimize operational noise.

Standard power supply is 220 V with a 110 V option, and peak power consumption sits around 2 kW. Essential maintenance entails inspection of the humidity tank, drainage ports, and regular verification of system components to ensure ongoing reliability.

What Sets Torontech’s Benchtop Series Apart

The advantages of this benchtop environmental chamber include:

• Compact but capable: High-end environmental testing without needing a walk-in chamber
• Climate precision: Tight control over temperature and humidity parameters
• Built-in safety: Extensive protections and system alarms for uninterrupted runs
• Versatile operation: Modular programming for repeatable test scenarios
• Durable design: Industrial-grade materials and efficient cooling systems

This combination makes the unit ideal for R&D settings, QC labs, and educational institutions that require high performance in a compact footprint.

Unlocking Potential in Your Lab

Integrating this benchtop temperature chamber into your workflows offers:

1. Streamlined environmental stress testing of small components
2. Capability to simulate real-world aging and failure modes that require precise climate control
3. Rated performance that supports usage in certified labs, research facilities, and industry-grade QA processes

From electronics to pharmaceuticals, Torontech’s chamber bridges the gap between full-scale environmental chambers and tabletop convenience.
