Fullerton, Calif.-based Good Water Warehouse introduces OAKTON Instruments’ continuous monitors for constant display of important water quality parameters. These are AC powered and have bright LED displays for use in darker areas. Probes are supplied with 1/2?? diameter tube (for user-supplied compression fitting) and a floatation assembly. These meters feature all push-button operation and calibration. They’re great for pre- and post-treatment monitoring of DI, RO and raw water.
