Quick ViewATI’s Model Q46D Dissolved Oxygen Monitor is designed to provide reliable oxygen measurement and help reduce operating costs. Two types of sensing technologies are available for use with the Q46D system: Membraned Electrochemical and Optical (fluorescence). Both sensors will provide reliable long-term performance with minimal maintenance. No hardware modifications are required to change from one sensor type to the other. The monitor can be configured for AC or DC power supplies, and a portable battery-powered unit is available to meet a variety of monitoring needs.

Quick ViewDissolved Oxygen Monitoring applications requiring a simple 2-wire transmitter or battery-operated instrument are easily satisfied using ATI’s model Q45D transmitter. Adaptable to either Optical or Galvanic D.O. sensors, this unit is ideal for installations where only analog signals are needed and low power operation is preferred. For applications requiring AC operation, relay outputs, automatic sensor cleaning, or digital communication, refer to ATI’s model Q46D brochure. ATI’s optical element is designed to last a minimum of 2-years in normal operation, but will more often provide a life of 3-5 years, unless mechanical damage occurs. Optical sensors do not require flow across the sensing element so accurate measurements can be made more accurately in systems with low flows. Unlike some optical sensors, this sensor is not degraded by exposure to sunlight. The Galvanic Dissolved Oxygen sensor uses a rugged 5 mil Teflon membrane to resist mechanical abrasions and tears. The membrane serves as a barrier to allow molecular oxygen to diffuse into the reaction cell where it is reduced, producing a small current which is proportional to oxygen concentration.

Quick ViewOn-Line monitoring of Ammonia in water is of increasing importance due to the increased emphasis on nutrient reduction in lakes, streams, and estuaries. Unfortunately, simple direct measuring sensors have not proven sufficiently reliable, and rather complicated systems have been developed to address the measurement problem. These systems can be used but require substantial maintenance and are expensive to purchase. ATI has developed a new approach to on-line monitoring of ammonia that is easier to operate and less expensive than competitive systems, but with the reliability you need.

Quick ViewATI’s Q46C4 4-Electrode Conductivity Monitor is the answer for monitoring almost any water-based process. Drinking water, plating bath solutions, cooling water, process wash water, or virtually any other aqueous system can be monitored accurately and reliably. The unique drive/control scheme used in the 4-electrode system allows a single sensor to be used in conductivity ranged from 0-2000 μS to as high as 0-2,000 mS (0-2 S.) For chemical mixing applications, a concentration display can be selected.

Quick ViewATI’s Model Q46C2 Conductivity Monitor provides the reliable and accurate low-level measurements required for such high purity water systems. Monitors provide large, easy-to-read LCD displays with a second display line for indication of temperature or other operational information and for those applications where results in resistivity units are preferred, Q46C2 monitors can be programmed to display readings in Meg-ohm units instead of microSiemens.

Quick ViewATI’s 4-Electrode Conductivity Transmitter is the answer for monitoring almost any water-based process. Drinking water, plating bath solutions, cooling water, process wash water, or virtually any other aqueous system can be monitored accurately and reliably. The unique drive/control scheme used in the 4-Electrode System allows a single sensor configuration to be used in conductivity ranges from 0-200 μS to as high as 0-2,000 mS (0-2 S). The “auto-ranging” feature enables the monitor to display the actual conductivity value during “overshoot” conditions. For chemical mixing applications, a concentration display can be selected for a limited number of acids and bases. If your application involves very low conductivity/resistivity measurement, ATI can provide the Q45C2 system that is used in process waters with conductivities below 200 μS.

Quick ViewATI’s 2-Electrode Resistivity Transmitter provides the reliable and accurate low-level measurements required for such high-purity water systems. Monitors provide large, easy-to-read LCD displays with a second display line for indication of temperature or other operational information. For those applications where results in resistivity units are preferred, Q45C2 monitors can be programmed to display readings in Meg-ohm units instead of microSiemens. The monitor employs 2-Electrode conductivity sensors with low cell constants to provide continuous measurements from 0-20 to 0-2,000 microSiemens. The 2-Electrode sensors are specifically designed for use in ultra-pure water and nonfouling applications. The sensors are available in several mounting configurations including 316SS compression fittings or sanitary-style. These sensors may also be mounted submersion-style or in a hot-tap configuration.

Quick ViewQ46H Monitors provide a large format concentration display with a second alpha-numeric lower line for secondary information. The monitor provides two standard 4-20 mA analog output and three SPDT relays. If desired, one analog output can be configured for PID control use. In addition, the monitor provides options for digital communications including Profibus-DP, Modbus-RTU, and Ethernet-IP. Auto-Chem chemistry systems include peristaltic pumps for sample and reagents, air supply for the stripping system, and gas conditioning components. All components are easily accessible from the front of the unit making service quick and easy. Attached to the bottom of the enclosure is an inlet overflow chamber where sample and drain connections are made. A sample flow rate of 5 - 20 gallons per hour (300-1200 ml/min.) is recommended.
