  • Ideal for a range of applications

    In both natural and industrial environments
  • Saves time and money

    Using reaction chemistry
  • ATI Q45N Dissolved Ammonia Monitor

The Q45N is a Dissolved Ammonia Monitor designed for wastewater treatment and natural water quality monitoring applications. Standard ammonia monitors are often complex and expensive to run. The Q45N simplifies the measurement process using reaction chemistry and then takes measurements using an amperometric sensor, providing reliable measurements in the long term. The Q45N is available in a convenient fibreglass enclose (as pictured) or with the display and monitor separated, when a more convenient display location is required.
