The Roughness Tester - Print Surf Method (PPS) automatically measures the roughness of paper and board according to the Parker Print Surf method and meets or exceeds these industry standards: TAPPI T 555, ISO 8791-4, BS 6563, Paptac D.31P.
Features of Roughness Tester - Print Surf Method (PPS)
Superior Measurement Heads
The PROFILE/Plus PPS head design incorporates advanced and proprietary metal fabricating techniques. Electron beam welding means that measuring heads last longer and are more robust.
Unique Calibration Technique
The Roughness Tester - Paper & Board incorporates a dummy head system that does not require measurement head removal, so flow verification is fast and easy. O-ring Seal The O-ring seal of the PROFILE/Plus PPS eliminates the need for petroleum jelly and reduces cleaning frequency, thereby improving performance.
Top-side and/or Bottom-side Measurement
The ability to measure both sides of the sheet is a valuable time saver that eliminates the need to feed the same sample twice.
Precise Measurement Tolerances
The instrument measures reliably and accurately between 0.6 and 6.0 microns. It has been engineered to deliver precise results that can be used to fine-tune process variables in the production environment.
Choice of Backings
The PROFILE/Plus PPS comes with both a soft and hard backing to address all your testing applications.
Dry Diaphragm Air Compressor
It is equipped with its own dry diaphragm compressor to ensure that the measurement air is always clean.
Measuring Head Air Purge
This feature automatically removes foreign material from the measuring area to increase measurement reliability and improve accuracy.
High-Resolution Sensor
The built-in high-resolution sensor increases the accuracy of the airflow, ensuring more stable results and improved confidence levels.
Benefits of Roughness Tester - Print Surf Method (PPS)
- Superior measurement heads reduce the measuring head service frequency, thus lowering service costs.
- The unique calibration technique simplifies the operation of the instrument and saves time and money.
- O-ring seal eliminates the need for petroleum jelly thereby improving instrument uptime and availability.
- Top-side and/or Bottom-side measurement means fewer man-hours are required to complete testing and this reduces costs.
- Precise measurement tolerances ensure that the data is always accurate and reliable, thus reducing costly rechecks.
- A choice of backings and measurement pressures means that the same instrument can cover a wide range of applications, which lowers overall testing costs.
- Dry Diaphragm Air Compressor ensures that the measurement air is always clean thus eliminating the risk of costly repairs due to contamination.
- Measuring Head Air Purge automatically removes foreign material from the measuring area thereby reducing variability and allowing tighter control of the process.
- High-Resolution Sensor increases the accuracy of the airflow, ensuring more stable results and improved confidence levels, thereby reducing retests.
