Question/Answer

Where\'s the TORSTARA2210 - WetChem - Orion Star A221 pH Portable Meter probe?

Our line of pH meters is found here http://www.envexp.com/products/1-Wet_Chemistry/PH-pH_and_Electrochemistry/TO10-Economy_pH_Probes. For a field sampling unit I would recommend the AquaPro Professional or one of the low maintenance gel probes in the Economy pH probes section.
