100 L Capacity High and Low Temperature Test Chamber with -70°C Low Temperature

While a product might pass inspection at room temperature, its performance could shift after prolonged exposure to high or low-temperature environments. High and low-temperature test chambers enable engineering teams to study and analyze these changes under controlled, repeatable conditions.

HeJin specializes in the R&D and manufacturing of various industrial environmental test equipment. By communicating directly with the manufacturer to receive expert engineering support—and leveraging a wide range of configurable test chamber options—clients can thoroughly discuss details such as sample dimensions, temperature requirements, and testing procedures before selecting the ideal system.

Evaluate Performance Beyond Room Temperature

Temperature exposure can affect materials, assemblies, and components in different ways. Plastics may change dimensions, rubber compounds may become less flexible, and electronic assemblies may show changes in operating behavior. The outcome depends on the material, construction, exposure duration, and test conditions.

An environmental chamber provides a controlled space in which these effects can be investigated systematically. Engineers can establish a baseline, expose samples to a defined temperature, and compare their condition or performance before and after testing.

Testing Capabilities

Low-Temperature Testing

Low-temperature exposure can help evaluate material flexibility, dimensional stability, component functionality, and performance following cold storage or transportation.

Typical test subjects include rubber seals, plastic housings, connectors, sensors, and selected automotive components.

High-Temperature Testing

High-temperature exposure helps assess material aging, deformation, appearance changes, and functional behavior under specified thermal conditions.

Applications may include polymer components, electronic enclosures, industrial assemblies, and materials intended for warm operating environments.

Temperature Change Testing

Where the programmed profile and chamber performance are suitable, successive temperature conditions can be used to study the effects of temperature change.

For temperature-change testing, the transition rate, dwell period, number of cycles, and specimen monitoring requirements must be defined by the applicable test procedure. Do not assume that a chamber supports rapid thermal cycling simply because it offers high and low temperature settings.

Temperature and Humidity Testing

When a humidity-control configuration is specified, combined temperature and relative-humidity exposure can support investigations into environmental conditioning and material behavior.

The requested humidity level must be achievable at the selected temperature. Condensation, sample moisture sensitivity, and test duration should be considered when developing the test plan.

FAQs

Q1: What is the difference between an environmental test chamber and an environmental simulation test chamber?

The terms are often used interchangeably for equipment that controls environmental conditions. The specific capabilities depend on the configuration rather than the product name alone.

Q2: Is an 80 L chamber always suitable for small samples?

Not automatically. Consider the dimensions of the complete fixture, airflow clearance, sample quantity, and heat dissipation before choosing a capacity.

Q3: What is temperature uniformity?

It describes how temperatures vary across defined measurement locations in the chamber under specified conditions. It is different from temperature fluctuation at one location over time.

Q4: Does humidity accuracy indicate the full humidity operating range?

No. Accuracy and operating range are different specifications. Both should be confirmed, along with the permitted temperature–humidity combinations.

Q5: Can the chamber be configured for a special test requirement?

Customers can submit their requirements for engineering review. Feasibility depends on the target conditions, sample characteristics, and requested functions.
