Description :

This versatile kit turns your visible wavelength spectrometer and light source into a transmissive pH probe. It uses a randomized fiber bundle probe in a stainless steel, selected by the user based on environment. For example, long term monitoring in seawater would use the PEEK probe due to the corrosion sensitivity of stainless steel.

This kit can be used with your spectrometer system as a replacement for any traditional electrode pH sensor, and comes with 5 transmissive pH patches to get you started.

● Recommended for use with spectrometers configured with a 25 – 50 μm slit.
● Both light source and spectrometer must measure 620 nm and either 510 nm or >750 nm
● Samples must be clear, not colored or turbid.
● Sample volume is 3+ mL.
