Probes for Spectrometers

Different measurement situations require different probes to suit the application at hand. This is precisely why Polytec offers a selection of scan heads that can be used in direct contact with and even at a greater working distance from the goods being measured. Probes that can be immersed in the product to be analyzed are also available. Some sensors have already been combined with an illumination module and have an internal reference. Using a multiplexer system with fiber-optic switches, a spectrometer can be equipped with several probes which are used at different measurement points.


The PSS-H-A03 distance scan head is a reflection scan head that allows the user to carry out sample measurements at distances of between 150 and 600 mm. This makes it ideal for analyzing goods being measured on conveyor belts, for strip products and for similar applications. 


The PSS-H-B01 and PSS-H-B02 contact scan heads are reflection scan heads which allow you to measure samples – which are being transported through the likes of pipes, chutes and funnels – over short distances. 


The PSS-H-CR1 reflection immersible probe is the right choice for measuring liquid or viscous samples. The probe is also available in a version that is suitable for use in the food industry.


The PSS-H-CR2 reflection immersible probe can be easily integrated into pipelines or reactors. The innovative design with integrated reference enables you to control fluid media such as liquids, dispersions or pastes online. The probe can also be used for food analysis purposes.

PSS-H-117 Fiber Scan Head

The PSS-H-117, PSS-H-217, PSS-H-125 and PSS-H-225 fiber scan heads are used for transmission measurements (e.g. gases) or passive measurements (e.g. hot steel or glass).
