Description
To make life simpler, we have combined two different calibration standards into one. Calibrate for PTSA & Fluorescein using this combination calibration standard solution. This solution combines 100ppb of PTSA with 50ppb of Fluorescein to provide the perfect calibration solution for your PTSA + Fluorescein combination Pyxis Lab® devices, including:
SP-380 PTSA + Fluorescein Handheld
SP-710B Handheld Water Multimeter
NOTE: As of right now it is – due to a national shortage in chemical bottles – we are providing (2) 250mL bottles, but will hopefully be able to supply our normal bottle soon.
