Overview
The PN-WAT sanitary napkin water absorption rate tester is a special testing instrument designed and developed according to the national standard GB/T 8939, which is mainly used for the determination of the water absorption rate of female physiological sanitary napkins (including sanitary pads). The instrument evaluates the water absorption capacity of the product by measuring the ratio of the mass increased after absorption to the mass before absorption. The larger the water absorption rate, the stronger the absorption capacity.
Features
1. Adopt 5-inch Touchscreen display.
2. Fully automatic design, one key for measurement.
3. With statistical function, it can display the average, Standard Deviation and Coefficient of Variation.
4. Automatically return to the initial state after the test.
5. Built-in thermal printer, the test report can be printed directly at the end of the test.
6. Can be connected to the host computer control software.
Principle
The instrument calculates the water absorption ratio by measuring the ratio of the mass increase of the sanitary napkin sample after absorbing the liquid to the mass before absorption. It reflects the total water absorption of the product after soaking for a period of time, and is a key indicator for evaluating the polymer Resin Water Absorbency in the absorption layer.
Applications
Female physiological sanitary napkins, sanitary pads
Steps
1. Prepare samples.
2. Place the sample on the instrument.
3. Start measurement with one click through Touchscreen.
4. The instrument automatically completes the process of absorbing water, weighing, and calculating.
5. After the test, the instrument automatically returns, and the data can be displayed and printed.
Notice
• Power supply voltage is AC 220V +/- 10% 50Hz.
• The instrument should be used at Ambient Temperature (20 +/- 10) ℃ and relative humidity < 85%.
• Please familiarize yourself with the functions and standard requirements of the instrument before operation.
• Regular maintenance to ensure Measurement accuracy.
