1.0 Photometer Liquid reagents kit to Measure

This reagent seems to work well. I know the results are consistent.

The liquid drops in the pool lab 1.0 is not very accurate do not buy and waste your money.

Unfortunately the system is not accurate

Don't waste your money, the folks in Germany should be very embarrassed. Hard to squeeze bottles, with different results every time test is repeated and not even close to Taylor results.
