This Hellma transflexion probe has been specifically designed for
the use in laboratories and research units. It provides high flexibility as well as robust design which withstands even rough process
conditions.

All-quartz immersion probes from Hellma have a probe head made of quartz that is fused to a quartz tube, forming a leakproof seal. For this reason, these probes are particularly useful for measurements in corrosive solutions.

Hellma standard immersion probes are ideally suited to laboratory measurements. As with conventional cell measurements, the collimated light beam passes through the solution only once.

ATR probes are suitable for situations involving the direct measurement of strongly absorbing solutions, where standard transmission probes cannot be used.

These Hellma Micro Immersion Probes have been specifically developed for measurements in small volumes...

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...

These Hellma transmission probes are, amongst other things, suitable for special application conditions in process monitoring at high temperatures and pressures.

The Hellma Fluorescence Immersion Probe makes it possible to measure fluorescence outside of a fluorimeter, directly in the medium being investigated...

These Hellma reflection probes are especially suitable for measurement of diffused reflection in the Vis and NIR range with FT-NIR spectrometers or diode array spectrometers.

This Hellma transflexion probe has been designed specifically for straightforward installation in quick-change fittings. Change your probe or sensor without interrupting the process.

This Hellma immersion probe withstands extreme process conditions and due to its monolithic sapphire head this probe is the ideal solution for highest demands.

Upgrade all established fibre-optic process probes with the additional Hellma module made of stainless steel 1.4571 (316 Ti)
