Complete free-chlorine measurement system for fresh water. Includes 499ACL chlorine sensor, 56 or 1056 transmitter, optional pH sensor (for pH-corrected reading up to pH 9.5), and constant-head flow controller. Continuous pH correction eliminates the reagents and sample-conditioning systems of competing chlorine analyzers.
Rosemount is configurator-heavy and quote-only — Valley Instrument verifies option compatibility, lead time, and pricing before confirming your order.
