DRK311-2 Infrared Water Vapour Transmission Rate Tester
Function
Use to test the water vapour transmission performance, water vapour transmission rate, transmission amount, transmission coefficient of plastic, textile, leather, metal and other materials, film, sheet, plate, container etc.
Working Principle
Wavelength-modulated laser infrared trace water sensor (TDLAS).
Nitrogen of a certain humidity is flowing on one side of the material, and dry nitrogen (carrier gas) is flowing at a fixed flow rate on the other side; the difference in humidity between the two sides of the sample drives water vapour to permeate from the high humidity side to the low humidity side of the sample; the permeated water vapour is carried by the flowing dry nitrogen (carrier gas) to the infrared sensor; the sensor measures the water vapour concentration of the carrier gas; and, based on the water vapour concentration of the carrier gas, calculates water vapour permeability and other parameters for the specimen’s parameters.
Standards that comply with
Chinese Pharmacopoeia (four parts) – water vapour transmission rate method, YBB 00092003, GB/T 26253, ASTM F1249, ISO 15106-2, TAPPI T557, JIS K7129.
Product Features:
1.Wavelength-modulated laser infrared microwater sensor, ultra-long range (20 metres) absorption, high accuracy.
2.Decay auto-compensation: no need for periodic re-calibration, no continuous data decay.
3.Humidity control: 10%~95%RH , 100%RH, fully automatic, no fog.
4.Temperature Control: Semiconductor hot and cold two-way control, high precision, stable and reliable.
5.Super environment adaptation: indoor environment, temperature 10 ℃ – 30 ℃ , no humidity requirements, low cost of use.
6.Sample anti side leakage sealing installation technology.
7.Fully automatic: one-key start, the whole process of intelligent; power failure data preservation; boot fault self-detection, to avoid fault state testing.
8. Software: graphical, whole process, full element monitoring; multiple report formats.
