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 PAS-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. They are used to analyze liquids, powders or bulk materials. The combined illumination and sensor unit is suitable for sample distances of 0 to 50 mm and has an integrated reference. The B04 version of the contact scan head is explosion-proof according to the ATEX-certified.
