Overview
The CHENCHI ZLS-200 paper filtrate velocity meter is a special instrument for measuring the filtration speed of filtrate paper and filtrate Cardboard with a certain wet strength. The instrument calculates the filtrate velocity by the time required for 100ml or 50ml of water to flow out of the 35.7mm diameter paper sample under the condition of a pressure difference of 1Kpa on both sides of the paper sample, but it cannot be used for filtrating materials processed by Resin or on non-hydrophilic surfaces.
Features
1. Touch screen operation, Multi-Parameter can be set
2.100Ml/50ml gear can be switched
3. The instrument automatically calculates the final filtrate speed result according to the filtrate time
4. Result saving and statistical printing of multiple sets of results
Principle
The time required for the instrument to flow out 100ml or 50ml of water through a 35.7mm diameter (10cm ² area) paper sample under the condition that the pressure difference on both sides of the paper sample is 1Kpa (ie 100mm water column), the time is expressed in seconds, and the filtrate speed is automatically calculated.
Applications
Determination of Water Filtration Speed of Filtrated Paper and Filtrated Cardboard with Certain Wet Strength
Standards
GBT10340 Paper and Cardboard filtrating speed
Steps
1. Set test parameters
2. Select 50ml or 100ml gear
3. Place the pattern for testing
4. The instrument automatically calculates and displays the filtrate speed result
5. Save or print multiple sets of result statistics
Notice
• Cannot be used for filtrated paper and filtrated Cardboard processed by Resin, or whose surface is not hydrophilic or not completely hydrophilic
• Working environment requirements: indoor temperature 20 +/- 10 ℃; relative humidity < 85%; clean and less dust, no strong magnetic field, no strong vibration source
• power requirements: 220V 50HZ
