Rosemount 499ACL‑02 Total Chlorine Sensor, Reagent-Based Inline Water Analysis Probe for Industrial Water Treatment Monitoring

Rosemount 499ACL‑02 Reagent-Driven Total Chlorine Sensor for Continuous Water Quality Analysis

Unique Working Principle of Rosemount 499ACL‑02 Chlorine Detection

Reagent-Based Total Chlorine Measurement Logic

Rosemount 499ACL‑02 adopts specialized reagent-dependent measurement technology, distinguishing it from free chlorine and monochloramine sensor variants. The probe relies on a matched TCL sample conditioning system to complete chemical reaction with water samples, achieving precise total chlorine quantification that covers combined chlorine and free chlorine components in aqueous solutions.

Stable Electrochemical Sensing Mechanism

Built with high-sensitivity electrochemical sensing elements, Rosemount 499ACL‑02 converts chlorine concentration changes into stable electrical signals. Optimized membrane structure isolates water impurities and suspended solids, effectively preventing probe contamination and signal drift during long-term inline immersion operation.

Datasheet-Verified Model Code Definition of Rosemount 499ACL‑02

Standard Suffix Parameter Decoding

Every segment of Rosemount 499ACL‑02 represents fixed factory functional configurations, with no field modification required. The coded parameters define sensor type, measurement medium and core working mode for accurate project model matching.

• 499ACL: Core industrial liquid analysis sensor platform dedicated for chlorine concentration monitoring

• ‑02: Exclusive total chlorine measurement configuration, requiring reagent-based TCL sample conditioning system for normal operation
