ATI Q46N Dissolved Amomonia Monitor

ATI’s Dissolved Ozone Transmitter is the ideal choice for on-line monitoring and control of ozonation systems. Capable of measuring DO3 concentrations as low as 0-200 ppb full scale, the system provides the sensitivity needed for demanding applications such as pharmaceutical grade water or semiconductor wash water and with the standard 0-2 ppm range, the monitor is ideally suited to water bottling systems or municipal water treatment. Even high range applications requiring 0-20 or 0- 200 ppm can be easily accommodated. Utilizing a highly selective polarographic membraned sensor, dissolved ozone can be monitored interference-free, with little maintenance. There are no moving parts and what little maintenance is required can be done in just a few minutes. Installation is simple and you can be up and running in a few hours. Available in loop-powered or battery operated portable versions, the Q45H/64 is well suited for almost any DO3 measurement requirement.

Dissolved 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.
