These Hellma micro immersion probes have been specifically developed for measurements in small volumes. Due to their slim form, less sample material is required for a measurement to be taken.
Immersion Probes for Small Volumes
The sample flow at the location where the measurement takes place is only minimally modified due to the compact form of the probes. High quality coated mirrors, together with carefully optimised optical geometry, ensure that these probes have outstanding transmission characteristics.
