1. What Is a Humidity Chamber?
A humidity chamber is an environmental test cabinet used to expose materials, components or finished products to
controlled temperature and relative humidity conditions. By maintaining a defined test environment, laboratories
can observe physical changes that may occur when products encounter moisture-rich or changing climatic
conditions.
For manufacturers, the value of controlled conditioning is practical: it helps reveal moisture-related weakness,
dimensional changes, surface deterioration and other performance shifts before products reach demanding field
conditions. The Presto Prima model is designed for this type of controlled environmental simulation and material
evaluation.
Why Controlled Humidity Testing Matters
• Creates repeatable environmental conditions for laboratory comparison.
• Helps evaluate how materials respond to prolonged humidity exposure.
• Supports quality control, product development and pre-production validation.
• Makes it easier to compare samples before and after environmental conditioning.
• Can support testing programs across packaging, plastics, automotive, electronics and other manufacturing
sectors.
How the Chamber Works
1 Set the required temperature and relative humidity on the touch-screen controller.
2 Place prepared test specimens on the sample racks inside the chamber.
3 The system manages heating, cooling, humidification and dehumidification to establish the set conditions.
4 Air circulation helps maintain a more uniform environment around the samples.
5 Temperature and humidity data can be monitored and recorded for test review.
A well-controlled chamber is especially useful when the goal is repeatability. Stable conditions reduce the risk that
test results are influenced by uneven temperature or moisture distribution.

3. Industry Applications of Humidity Testing
Humidity exposure can influence strength, dimensions, adhesion, appearance, electrical behaviour and long-term
reliability. For this reason, controlled humidity conditioning is relevant to multiple manufacturing and quality
assurance environments.
Industry Typical testing purpose
Packaging & Paper Condition paper, board, labels and packaging materials before evaluating mechanical or physical
performance. Moisture can change stiffness, dimensions and handling behaviour.
Plastics & Polymers Study moisture-related changes in polymer samples and finished parts, particularly where
environmental exposure can affect dimensions or surface properties.
Automotive Components Support environmental conditioning of components and materials where humidity and temperature
changes can influence durability and functional performance.
Electronics & Electrical Use controlled humidity exposure as part of environmental reliability programs for components,
assemblies and protective materials.
Paints, Coatings & Adhesives Evaluate the behaviour of coated or bonded materials after controlled environmental conditioning
and identify changes in surface or adhesion performance.
Textiles & Materials Condition samples under controlled humidity before selected physical or comparative laboratory
measurements.
Consumer Products Support product-development and quality-control studies where tropical, humid or variable climates
are part of the expected service environment.
Common Outcomes to Monitor
Depending on the material and test method, laboratories may monitor dimensional change, surface appearance,
weight or moisture effects, mechanical properties, adhesion, corrosion-related behaviour, electrical performance or
other product-specific characteristics. The test method should define the exposure conditions and acceptance
criteria.

4. Standards, Test Planning & Selection
The referenced Presto product page lists ASTM D1776 and ASTM D1776M-15 in relation to humidity conditioning.
The exact test settings, specimen preparation, exposure duration and acceptance criteria should always be taken
from the applicable standard or customer specification.
Before Buying a Humidity Chamber, Check These Points
• Temperature range: Confirm that the chamber covers the highest and lowest temperatures required by your
test program.
• Humidity range: Check the required RH window rather than selecting a chamber only by chamber size.
• Accuracy and resolution: Match controller and sensor performance to the tolerance of the test method.
• Internal volume: Consider specimen size, number of samples and rack spacing so airflow is not unnecessarily
restricted.
• Uniformity: Ask how air circulation supports consistent conditions throughout the working space.
• Data handling: If traceability matters, confirm data logging, USB or other communication requirements.
• Material of construction: Stainless-steel construction can support durability and corrosion resistance in humid
operating conditions.
• Service support: Evaluate installation, calibration, maintenance and technical support before finalising the
supplier.
Practical Test Workflow
1 Define the standard or internal test method.
2 Prepare and label specimens.
3 Set temperature and RH conditions.
4 Condition samples for the specified exposure period.
5 Record environmental data and observations.
6 Evaluate the required physical or performance properties.
7 Compare results with acceptance criteria and document the test.
