Product catalog summary
Introduction
The Total Chlorine Monitor Model Q46H/79S is designed for monitoring chlorination in potable water, wastewater effluent, and industrial cooling water. Chlorination is essential for controlling biological activity and ensuring safety in water systems.

Non-Contacting Total Chlorine Monitoring
This monitor uses a gas-phase approach to measure residual chlorine, which can exist in various chemical forms. The system converts all chlorine species into molecular iodine using a pH 4 buffer and potassium iodide, allowing for a comprehensive 'Total Chlorine' measurement.

Theory of Operation
The Q46H/79S employs an Auto-Chem chemistry module for sample treatment, air stripping of iodine, and gas measurement. The iodine is stripped from the sample and measured without contact with the sensor, preventing fouling.

Installation
The system consists of an Auto-Chem chemistry module and an electronic unit. It requires AC power and includes a 25 ft sensor cable, extendable up to 100 ft. The monitor provides a clear display and supports digital communications.

Features
- Gas Phase Sensing: Eliminates sensor fouling.
- Standard Method: Uses EPA-recommended iodometric measurement.
- Analog Output Options: Includes two isolated 4-20 mA outputs.
- Digital Communications: Supports Profibus-DP, Modbus-RTU, and Ethernet-IP.

Specifications
- Sensor: Membraned I2 Gas Sensor
- Response Time: 95% in 3 minutes
- Power: 115 or 230 VAC
- Operating Temperature: 2 to 50°C
- Enclosure: Kydex with acrylic cover

Ordering Information
Model Q46H/79S-A-B with options for power and digital output configurations.

Additional Solutions
ATI also offers the Q46S/66 Residual Sulfite Monitor for dechlorination control, using a similar air-stripping system for sensitive sulfite monitoring.

Total Chlorine Monitor Model Q46H/79S-1

Chlorination of potable water, wastewater effluent, and industrial cooling water is widely used throughout the world to control biological activity in the water. Disinfection of potable water with chlorine ensures that tap water is safe to drink after passing through the distribution system piping. Wastewater disinfection helps to ensure that receiving streams are safe for recreational use, and cooling water chlorination reduces biofouling that can degrade heat transfer efficiency. This wide use of chlorination for disinfection purposes results in the need for a reliable “residual chlorine” analyzer that can operate in a variety of applications.

Total Chlorine Monitor Model Q46H/79S-2

Residual chlorine is found in many chemical forms in water systems. Residuals in clean water are often predominantly free chlorine while wastewater and cooling water can contain mixtures of free chlorine, combined chlorine, and organochlorine species. Measurement of residual chlorine in applications where only free chlorine (potable water) or only combined chlorine (chloraminated water) exist can often be monitored with direct sensor measurement. However, applications where a variety of chlorine forms can exist (wastewater effluent and some cooling water) require a more complicated measurement...
