In modern laboratories and production facilities, a benchtop humidity chamber is an essential tool for testing product durability under extreme environmental conditions. Compact yet powerful, it simulates high and low temperatures, as well as wet heat cycles, to ensure products perform reliably in real-world scenarios.
Compact yet versatile, a benchtop humidity chamber delivers precise control of temperature and humidity, offering the same reliable performance expected from advanced benchtop environmental chambers and benchtop temperature humidity chambers.
A benchtop humidity chamber is a small, laboratory-friendly environmental test unit that fits conveniently on a workbench. Despite its compact design, it supports demanding tests such as:
High-temperature exposure
Low-temperature stress
Wet heat cycle testing
These chambers are ideal for electronics, automotive parts, medical devices, polymers, coatings, and aerospace components, offering reliable results without occupying large floor space.
Process: The chamber’s heating system raises the internal temperature, often up to +150°C.
Purpose: Identifies potential issues like material expansion, deformation, discoloration, or electronic instability.
Standards Referenced: Commonly performed following IEC 60068-2-2, ISO 16750-4 (automotive components), or MIL-STD-810H (military equipment).
Process: Advanced refrigeration lowers the chamber temperature to –40°C or –70°C.
Purpose: Detects brittleness, cracking, seal failure, and electronic malfunctions due to extreme cold.
Standards Referenced: Typically conducted according to IEC 60068-2-1 and other internationally recognized methods.
Together, these tests replicate extreme climates—from scorching desert heat to arctic cold—helping engineers evaluate long-term product reliability.
The chamber alternates between heating and cooling phases.
Relative humidity levels are increased to 95–98% RH.
Cycles repeat over hours or days to accelerate material aging and degradation.
Simulates tropical environments, rainy climates, or condensation inside sealed devices.
Reveals risks such as corrosion, swelling, leakage currents, or coating failures.
IEC 60068-2-38: Cyclic damp heat test
ASTM D2247: Moisture-resistance testing for coatings and polymers
These tests provide reliable, repeatable results that comply with international standards, ensuring confidence for global product deployment.
A benchtop humidity chamber can accommodate a wide variety of test samples, including:
Electronics: Circuit boards, sensors, semiconductors, connectors
Automotive parts: Switches, dashboard components, plastics, seals
Medical devices: Sterile packaging, surgical instruments, diagnostic tools
Materials: Polymers, adhesives, paints, coatings, laminates
Aerospace components: Wiring, composites, protective coatings
