All-Quartz Immersion Probe With Large Optics
|Application example||Measurements in cloudy solutions|
|Particular characteristics|| |
As with all the Hellma all-quartz immersion probes the body of this probe is manufactured entirely of quartz, so no other materials can come into contact with the product. The advantages of the Hellma measuring head (passing of light through the sample only once, precise optical light paths despite varying temperatures) are thus augmented by the high chemical resistance of the quartz. In addition, the optics in this construction are so arranged that the beam diameter in the sample gap is exceptionally large. As a result variations in the concentration of the product in the gap are evened out, thus making it also possible to measure cloudy solutions.
