Technidyne PROFILE/Plus® TAPPI Opacity

The Technidyne PROFILE/Plus® Opacity accurately and automatically evaluates paper opacity to TAPPI Method T425 standards. 


Brought to you by Technidyne, our specialist optical, surface, and physical property testing brand, the Profile Plus device evaluates the TAPPI opacity of paper samples, in seconds. 

The PROFILE/Plus® Opacity is a fully-automated TAPPI opacity measurement device. It’s both accurate and precise. It performs  fully automated paper opacity measurements. This increases efficiency and lowers overall testing costs. 

The fast, accurate paper opacity measurements the Profile Plus takes provides the data needed to make positive process changes. Changes to improve quality or to enhance profitability. 

A fast, industry-focused TAPPI opacity machine 

The TEST/Plus® TAPPI Opacity uses industry standardized measurement technology for the most reliable and useful paper opacity testing. Plus it’s really fast – providing you with data in mere seconds.  

Automatic paper opacity testing

Our TAPPI T425 paper opacity tester operates automatically to ensure precise alignment and controlled loading of your sample and the backing. 

With the PROFILE/Plus® TAPPI Opacity you get an inbuilt profile automatically with the built-in Paper Advance System (PAS). This allows you to cross check across the entire web to better meet any customer’s opacity testing needs.  

Faultless paper opacity measurement

The simple operation of the Profile Plus eliminates operator errors. This promotes confidence in the TAPPI opacity test results, enabling tighter process controls and soon saving you money. 

Good-looking TAPPI opacity testing

A consistent appearance is an important attribute for the makers of paper products. If a company wants to impress, they need their products to look good across every batch. 

Paper opacity testing helps makers of paper products to guarantee consistently high standards. The TAPPI Opacity is part of our popular PROFILE/Plus® line of instruments. Use it to guarantee the most accurate paper opacity measurements of your products or packaging.  

Calibration data protection

The PROFILE/Plus® TAPPI Opacity uses standardized calibration data you can rely on. It helps you to determine whether or not your products are ready to be shipped, reducing customer complaints further down the chain.. 

Infrared paper opacity testing

The PROFILE/Plus® TAPPI Opacity has an infrared heat filter to maintain proper measurement conditions. This built in facility helps to ensure stable and reliable TAPPI opacity results. 

Quality TAPPI opacity technology 

The Technidyne PROFILE/Plus® TAPPI Opacity meets or exceeds the standards called for both TAPPI T425 and to ASTM D589
