499ACL-03: Measures monochloramine without reagents or sample pretreatment.
Emerson 499ACL-03 is a sensor for measuring monochloramine in water. Here is a detailed description:
Measuring principle: It belongs to the amperometric sensor family and directly measures monochloramine without reagents or sample pretreatment through ion-selective electrode technology.
Technical parameters
Measuring range: Typically 0 to 10 ppm (mg/L) as Cl₂, higher ranges require consultation with the factory.
Response time: 22 seconds.
pH range: 6 to 9.5.
Operating temperature range: 32 to 131°F (0.0 to 55°C).
Operating pressure: 0 to 65 psig (101 to 549 kPa).
Electrode membrane: Liquid-ion exchange.
Sample type: Aqueous.
Electrode type: Chlorine.
Appearance and mounting options: Flow-through.
Maximum diameter/width: 1 inch (25.4 mm).
Maximum length: 7.75 inches (197 mm).
Product features
No reagents and pretreatment required**: No cumbersome and expensive reagents or sample pretreatment are required, reducing the cost of use and the difficulty of operation.
Easy maintenance: The diaphragm is easy to replace without special tools, and can automatically compensate for temperature-related membrane permeability changes. The Vario Pol connector option allows the sensor to be replaced without replacing a new cable, which can effectively reduce maintenance time and costs.
Accurate measurement: Automatically corrects the pH value to at least 9.5 to ensure accurate measurement of monochloramine content under different pH conditions.
Application scenarios: Mainly used in various scenarios where monochloramine content in water needs to be monitored, such as municipal and industrial water treatment plants, swimming pools, food processing industries, etc., to ensure water quality safety and the effectiveness of the treatment process.
