PTSA probes measure trace fluorescent chemical in parts per billion. They are precise, sensitive instruments, and need the right setup and care to perform well. These guides cover using them with the MicroVision EX. For how fluorescence measurement works, and each probe’s interface and ratings, see Fluorescence (PTSA), the Pyxis ST-500, and the Turner Designs LD2.
