Ultra-Mini Immersion Probes
The type 661.602 probe is an ultra-mini immersion probe with SUPRASIL 300 quartz prism and corrosion-resistant titanium barrel. The collimated light beam passes the solution to be measured twice. The separate beam path and use of a deflecting prism with two totally reflective surfaces leads to very low values for stray light.
The type 661.622 probe is an ultra-mini immersion probe with removable light path tips. The tips can be exchanged simply and easily to adjust the light path between 1 mm and 20 mm. After passing through the solution to be measured, the light beam is reflected by a rear-coated mirror and passes through the solution a second time.
