Hi Bob, No I didn't because the unit came with the reagents supplied by Hanna. No reason to try and second guess the manufacturer, eh? We followed their directions to the letter and it never gave reliable readings. Nor was it repeatable. It is made for measuring silver in effluent, etc.
The PWT is still the best choice for most people.
