Total Sulfur Analyzer
Model T108
-
Teledyne Advanced Pollution Instrumentation
The Model T108 Total Sulfur analyzer is designed to measure mixed sulfur impurities, collectively referred to as Total Sulfides, in air or carbon dioxide gas. Since there is no scrubber in the system, the instrument reading is the sum of the oxidized sulfur compounds and SO2.The Model T108 consists of a modified Model T100 SO2 analyzer with special software and a Model 501TS high temperature thermal oxidizer. Sulfur compounds are heated as they pass through the converter and oxidized into SO2. When analyzing CO2, which generally contains no oxygen, approximately 6% O2 is added to the sample before entering the converter. This dilution is corrected in the calibration procedure.

ACCUplace Dot Distortion Target
AP-DD Series
-
All machine vision lenses will show some type of distortion. Minimizing or correcting that distortion is crucial in most applications. The ACCUplace Dot Distortion target is designed to detect the presence of both barrel/pincushion distortion as well as alignment distortion that causes the keystone effect. The precise amount of distortion is determined from an array of precisely placed dots in a regular array. The results can be used to correct for any distortion that occurs within the optical system. The AP-DD is offered on three standard substrates; Chrome on Glass (CG) Opal (OP) and Photo Paper (RM).
