These are AC powered and have bright LED displays for use in darker areas. Probes are supplied with ½” 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.
