Pyxis PTSA Combined Standard, 100 ppb PTSA + µS 1000, 500 mL

This dual-parameter standard includes a precise 1000 µS conductivity solution and a 100 ppb concentration of PTSA, making it ideal for verifying and calibrating instruments such as the Pyxis SP-400 and SP-700 meters. This standard ensures accurate readings for both conductivity and PTSA tracing in cooling towers and reverse osmosis systems, simplifying quality control and inhibitor monitoring.
