Condition: Used
This Lakewood Instruments Model 200 Hydro Pure Conductivity Meter has been inspected and is in good used condition. It was pulled from a working environment where it was in active use and functional. The blue steel enclosure shows surface rust along the edges and top, with general wear and paint scuffing consistent with industrial service — visible in the photos. The front panel controls, analog conductivity meter, and indicator LEDs are all present and intact. The solenoid valve assembly (Jack Evans Controls, 120V), 3/4-inch PVC SCH 40 pipe fitting (Spears), and power cord are included. Please view our photo set and contact us if you have any questions.
