Water Vapor Transmission Rate Analyzer - Infrared Method

W-IR-31-H
Focusing on packaging and material testing technology, we are committed to quality control in industries such as healthcare, pharmaceuticals, food, packaging, textiles, and new materials. Our products are widely used in enterprises, testing institutions, universities, and research institutes.

Category:

Permeation Analyzer

Water Vapor Transmission Rate Analyzer

WVTR Tester- Infrared Method

Function:

Water vapor permeability testing - water vapor transmission rate, permeation amount, permeation coefficient.

Used for Membranes, films, sheets, containers made of materials such as plastic, fabric, leather, metal, etc.

Principle:

Wavelength-modulated Tunable Diode Laser Absorption Spectroscopy (TDLAS) for trace water sensing. Nitrogen gas at a certain humidity flows on one side of the specimen, and dry nitrogen gas (carrier gas) flows on the other side at a fixed flow rate. The humidity difference of the sample drives water vapor to permeate from the high humidity side to the low humidity side. The permeated water vapor is carried to the infrared sensor by the flowing dry nitrogen gas (carrier gas). The sensor measures the water vapor concentration in the carrier gas. Based on the water vapor concentration in the carrier gas, parameters such as water vapor permeability of the sample are calculated.

Compliant Standards:

ASTM F1249, ISO 15106-2, TAPPI T557, JIS K7129, Chinese Pharmacopoeia (Part Four) - Method for Determination of Water Vapor Permeability, YBB 00092003, GB/T 26253.

Product Features:

Wavelength-modulated tunable diode laser infrared micro water sensor with ultra-long optical path (20 meters) absorption and high accuracy.
Automatic attenuation compensation: No need for regular recalibration, no continuous data decay.
Humidity control: 35%~90% RH, fully automatic, no fog.
Temperature control: Semiconductor cooling and heating bidirectional control, high precision, stable and reliable.
Strong environmental adaptability: Indoor environment, temperature 10°C-30°C, no humidity requirements, low operating costs.
Sample installation: Pneumatic clamp sample (H-type). Sample anti leakage sealing installation technology.
Fully automatic: One-key startup, fully intelligent; data saved in case of power outage; self-check at startup to avoid testing in a faulty state.
Software: Graphical, comprehensive, all-element monitoring; multiple report formats.
Optional: GMP Computerized System functional module.
