Water Vapour Permeability Tester

Introduction

A water vapour permeability tester measures moisture transmission through materials. It is widely used in textiles, packaging, and materials research. The system ensures breathability evaluation. It solves subjective assessment issues. By providing standardized testing, it supports product performance analysis.

Standards

Complies with the above standards, but is not limited to them.

Features

1. Interchangeable holders or cells suit different materials.

2. Clear display shows flow, pressure and result.

3. Bench design fits testing laboratories.

4. Clamping and sealing systems prevent edge leakage.

5. Multiple ranges cover low to high permeability.

FAQ

What is the Water Vapour Permeability Tester mainly used for?

The Water Vapour Permeability Tester is used to measure how readily air, gas or vapour passes through materials such as textiles, films, paper, concrete or packaging. It supports material development and quality control in manufacturing.

Which standards and regulations apply to the Water Vapour Permeability Tester?

The tester is designed with reference to applicable ISO, ASTM and GB/T permeability methods and IEC 61010 electrical safety. Specimens and pressure conditions must follow the standard. Compliance documentation can be provided on request.

How long is the warranty period?

The complete unit carries a 12-month warranty from delivery, covering the main body, core components and controller against manufacturing defects. Consumables and wearing parts such as filters, seals and probes are not covered. Damage from misuse, improper power or unauthorised repair is excluded, and extended warranty can be quoted.

Is the Water Vapour Permeability Tester difficult to operate?

No advanced specialist skills are needed for standard operation, though correct sample handling and safety practice should be followed. We supply a detailed manual and start-up support. For multi-user or regulated sites, a short staff training session can be arranged.

How long does delivery usually take?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

How often should the Water Vapour Permeability Tester be calibrated?

Regular calibration keeps measurements within the stated accuracy; an annual check is typical, with shorter intervals for heavy or regulated use. Reference standards and procedures are described in the manual. We can quote calibration with certificates.

Are the consumables universal or proprietary?

Filters, seals, probes and similar items are standard and can be supplied through our channel. Customers may also source equivalent items that meet the specification. Provide the model and serial number to confirm compatibility before ordering.

Can the Water Vapour Permeability Tester be customised?

Customisation is supported for many installations, including tailored parameters, connections and accessories. Our team reviews the requirement and confirms feasibility and lead time in advance. We avoid committing to options that cannot be delivered reliably.

Do you provide on-site installation?

The unit is delivered ready for set-up, with clear commissioning steps in the manual. We provide remote technical support during installation. For larger or regulated systems, a factory-trained engineer can attend on site on request.

What should be avoided when using the Water Vapour Permeability Tester?

Do not use leaking seals, damaged specimens or uncontrolled pressure and flow. Condition samples and verify flow measurement. Follow the operating instructions.
