Wide Temperature Range Environmental Test Chamber with Multiple Chamber Capacities and Stainless Steel Construction

When products move between cold storage, hot production environments, and changing outdoor conditions, temperature can reveal weaknesses that are difficult to identify during routine inspection. HeJin’s Environmental Test Chamber is designed to help manufacturers, laboratories, and quality teams evaluate product performance under controlled temperature and humidity conditions.

The High and Low Temperature Test Chamber provides a controlled environment for evaluating how materials, components, and finished products respond to selected temperature and humidity conditions. It can support product development, incoming quality assessment, process verification, and reliability testing.

Rather than relying on assumptions about how a product will perform in service, engineers can use repeatable environmental conditions to observe changes in dimensions, appearance, electrical characteristics, material behavior, and overall functionality.

The required chamber configuration should be selected according to the sample dimensions, target temperature, humidity requirements, exposure duration, and applicable test procedure.

• Wide temperature selection: The referenced series lists low-temperature options from +25°C down to -70°C, with high-temperature options of +100°C and +150°C. Confirm the achievable combined operating range for the selected configuration.

• Multiple chamber capacities: Reference working-space options include 80 L, 100 L, and 225 L configurations.

• Temperature and humidity control: Supports environmental conditioning within the specified operating limits of the selected model.

• Stainless-steel construction options: The reference specification lists SUS304 stainless-steel sheet or a painted finish for the chamber’s internal and external construction.

• Compressor-based refrigeration: The reference configuration describes single-stage refrigeration for the 20°C range and two-stage refrigeration for lower-temperature operation.

Condition samples at a specified low temperature to evaluate their ability to withstand cold storage, transportation, or operating environments.

Expose samples to a controlled high-temperature environment to assess changes in material properties, dimensions, appearance, and functional performance.

Bring specimens to a defined temperature and maintain the required exposure period according to the test plan.

Where the selected configuration supports the required humidity range, the chamber can be used for controlled temperature and relative-humidity testing. Actual temperature–humidity combinations must remain within the equipment’s specified operating envelope.

Support repeatable test procedures for product development, quality control, and comparison of samples before and after environmental exposure.

Applicable International Test Standards

IEC 60068-2-1:2025 — Test A: Cold. Clause 1 defines the scope of cold testing; the test procedures and severity selection are addressed in Clause 6. Used to assess the ability of specimens to be used, transported, or stored at low temperatures.

IEC 60068-2-2:2025 — Test B: Dry heat. Clause 1 defines the scope of dry-heat testing; Clause 6 covers test procedures. Used to assess specimen performance under specified high-temperature conditions.

IEC 60068-2-14:2023 — Test N: Change of temperature. Clause 1 establishes the scope, and Clause 6 addresses test procedures. Used to evaluate the effects of specified temperature changes or successive changes on specimens.

IEC 60068-3-5 — Confirmation of the performance of temperature chambers. Relevant to confirming chamber performance using the applicable measurement and verification procedure.

IEC 60068-3-7 — Measurements in temperature chambers for tests A and B with the specimen present. Relevant when verifying chamber performance under loaded test conditions.

Q1: What is an environmental test chamber used for?

It creates controlled environmental conditions for testing how products and materials respond to temperature and, where supported, relative humidity.

Q2: Can this chamber perform both high- and low-temperature tests?

The reference series lists low-temperature settings down to -70°C and high-temperature settings of +100°C and +150°C. Confirm the actual operating range and whether the requested conditions can be achieved in one configuration.

Q3: What chamber capacity should I choose?

The reference options are 80 L, 100 L, and 225 L. Selection should account for specimen dimensions, clearance for airflow, fixtures, and the number of samples tested together.

Q4: Can the chamber perform humidity tests?

Humidity testing is available only when supported by the selected configuration. Confirm the required humidity range and the temperature–humidity combinations before ordering.

Q5: Does the equipment comply with IEC 60068?

The relevant IEC 60068 methods can guide the test procedure. Compliance must be assessed against the complete test requirements and verified chamber performance, rather than inferred from the product description alone.
