"OpTest offers advanced image analysis and process sensor technology developed to meet the needs of the Pulp and Paper Industry for accurate and reliable measurement of pulp or paper properties. We believe that equipment with sophisticated optics and software analysis should be easy to use. This philosophy is reflected in our products which incorporate state-of-the-art optics, sensors, and user control technology."

Paprican Micro-Scanner is a multi-purpose camera based image analyzer for visible dirt reported both in physical size and by equivalent black area; light feature analysis for pin holes and windows and stickies, paper formation quality analysis, solid print uniformity analysis and fleck detection.

Wide Format Image Analyzer for dirt count on large sample sheets. Gives you Equivalent Black Area and automatic threshold routines on samples up to 1m wide with 65 micrometer/pixel resolution.

Paper Perfect is a formation analyzer that lets the user decide how to compare formation. You can compare a sample against a perfect formation, or an industry standard formation or a company sample formation. In any case you get discernable numbers that can be used for future comparisons.

The Dynamic Sorption Tester uses the Bristow Technique to measure liquid sorption into paper or board. This test has a very short period of time where the liquid is in contact with the paper resulting in more realistic tests.

The Paprican Ink-Scanner is an image analyzer that measures the ink remaining in paper or board after recycling or de-inking. It illuminates the specimen with a near IR diffuse source. The instrument incorporates a state-of-the-art detector which collects and directly transmits the digital image to the processor for analysis. All adjustments are automatic. It is very quick and easy to use.

The Fiber Quality Analyzer rapidly, accurately and automatically determines the quality of cellulose fibers. It uses advanced image analysis to determine kink, curl, fiber length and fiber width. The special flow cell never clogs and rotary polarized light picks up fines while ignoring contaminants.

There is also an On-Line Fiber Quality Analyzer that determines the quality of cellulose fibers on line. No samples to take. No delay in seeing results to changes in process. It can interface to your DCS or PLC systems. Use this as a continuous feedback to your process to make immediate changes when the pulp changes.

The Domtar Lint Tester consists of a device for collecting the lint, or other debris, from an offset blanket (lab or production press) and a device for screening the lint to determine the mass fraction retained on a 150 and 400 mesh.

Paprispec is an on line system for monitoring plastic levels in pulp. It processes a continuous side stream of pulp where a reverse hydrocyclone concentrates the plastic particles in a reject stream while accepted pulp is returned to the process. The reject stream is processed further by a pressurized mini-screen. The screen removes any remaining pulp and retains the accumulated plastic until sampling is complete. The accumulated particles are then back-flushed from the mini-screen and sent to a collection cup.
