Despite its compact size, the chamber delivers industrial-grade environmental simulation performance, with a typical temperature range from –40°C to +150°C and humidity control from 20% to 98% RH, covering the majority of component-level environmental test requirements.

Unlike conventional compact chambers that only reduce physical dimensions, the LIB industry benchtop environmental test chamber maintains a full-function control architecture, including uniform airflow circulation, stable temperature gradients, and long-term operational reliability.
Temperature uniformity can be controlled within ±1.5°C, ensuring high repeatability across test cycles.

The chamber accurately simulates high temperature, high humidity, low temperature, and programmable temperature-humidity cycling, making it suitable for accelerated aging tests, screening tests, and early-stage product validation-all within a space-saving benchtop design.

Workroom

The chamber door is designed for safe, user-friendly operation.
It features a manual bi-directional locking mechanism with a recessed handle design, reducing protrusions and improving laboratory safety.
Double-layer high-elastic silicone sealing strips ensure excellent airtightness, effectively preventing heat loss and moisture leakage, even during long-duration humidity tests.

PID Controller

The chamber is equipped with a PID programmable color touch-screen controller, enabling intuitive operation through simple touch interaction.
The interface provides real-time monitoring of temperature and humidity, programmable test profiles, alarm management, and data visualization-making complex environmental tests easy to configure and repeat with high consistency.

Sample shelf

The sample shelves are manufactured from SUS304 stainless steel, ensuring structural stability and resistance to deformation under high temperature and high humidity conditions.
They are designed to support long-term, continuous testing while maintaining uniform airflow around test samples.

Temperature and Humidity Sensor

High-precision PT100 Class A temperature and humidity sensors are used to ensure accurate measurement and control.
With a resolution of up to 0.001°C, the sensor system enables highly stable environmental control, making test results repeatable, reliable, and suitable for critical R&D and validation applications.

FAQ – Benchtop Environmental Test Chamber

Q1: How does a benchtop environmental test chamber differ from a standard vertical chamber?

A benchtop chamber is optimized for small samples and limited space, but the LIB industry model retains the same control logic, airflow design, and reliability standards as full-size chambers-ensuring no compromise in test accuracy.

Q2: Is a benchtop environmental chamber suitable for long-term cyclic testing?

Yes. Thanks to its industrial-grade refrigeration system, PID control, and stainless steel workroom, the chamber supports long-duration temperature-humidity cycling with stable performance.

Q3: Can a benchtop environmental test chamber achieve 5 °C/min or 10 °C/min fast temperature change?

Yes.
Despite its compact size, the LIB industry benchtop environmental test chamber can be customized to achieve 5 °C/min or up to 10 °C/min fast temperature change.
High ramp rates are available through non-standard configuration, tailored to test volume and heat load requirements.
