Product Details

Product Name: Building Material Water Vapor Transmittance Tester - Weighing Method
Product Code: 1133417748454068224

W-B-61-F-1

Function

Water vapor transmission performance test - water vapor transmission capacity, transmission rate, transmission coefficient, wet flow density, and moisture permeability.

Suitable for testing the water vapor transmission performance of building materials, thin sheets, and other samples.

Working principle

Balance weighing: integrating weight loss and weight gain methods.

Drying agent in the sample cup (weight gain method) or placing water (weight loss method); Seal the sample cup with the sample and place it inside the testing box; Control the temperature, humidity, and wind speed of the test box; The humidity difference inside and outside the sample cup drives water vapor to penetrate the sample, resulting in an increase or decrease in the mass of the sample cup; Regularly weigh the sample cup and calculate performance parameters such as the water vapor transmission rate of the sample.

Execution standards

ASTM E96, GB/T 17146, GB/T 21332, QB/T 2411, etc.

FEATURES

Strictly comply with domestic and international standards, and customize thick samples for building materials and other materials.
Tested for 48 hours, with a test error of less than 0.05 g/m²•24h， And as the testing time approaches zero.
Humidifier fog free: completely gaseous, fog free, avoiding false infiltration caused by fog settling.
Humidifier built-in: Moisture directly enters the testing chamber without flowing through the low-temperature zone, ensuring stable high humidity.
Patent wax sealed cup: Reliable sealing, convenient wax pouring, can encapsulate sample thickness of 150mm.
Temperature and humidity: automatic humidity control, automatic water replenishment; Semiconductor cold and hot bidirectional temperature control.
Balance protection: patented insulation and moisture prevention technology ensures the stability and lifespan of the balance.
Uniform wind speed: Double plane spiral circulation wind with uniform wind speed, humidity, and temperature fields.
Fully automatic: One click testing, automatic end and data saving; Drying machine desiccant circulation regeneration.
Working environment: Indoor, no need for constant temperature and humidity environment (reducing usage costs), test data is not affected by environmental temperature and humidity.
Fault self check: Power on self check to avoid testing under fault conditions.
Data recording: graphical, full process, all element recording, no loss of power-off data.
Data Security: The optional "GMP Computerized System" software module has functions such as user management, permission management, and data audit tracking.
