REFLECT-PH-KIT

Model : REFLECT-PH-KIT

Description :

This kit with pH patches, factory tested and applied to cuvettes, turns your visible wavelength spectrometer and light source into a non-invasive pH probe. The kit consists of a fiber attached to a sample holder, light source and spectrometer.

The reflective pH patches coatings are capable of monitoring pH 5 – 9 in liquids. Applications for this kit include bioreactor monitoring (such as fermentation) and process line monitoring.

● Recommended for use with spectrometers configured with a 50 – 100 μm slit.
● Both light source and spectrometer must measure 620 nm and either 510 nm or >750 nm
