Continuous, 2-Wire Transmitter for Battery-Operated Monitoring

Adaptable to either Optical or Galvanic D.O. sensors, the Q45D Dissolved Oxygen Monitor is ideal for installations where only analog signals are needed and low-power operation is preferred. The 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.

  • Industrial Pre-Treatment

    Industrial pre-treatment is a crucial stage in the water cycle, occurring before wastewater enters municipal treatment facilities. It involves the removal of contaminants, pollutants, and other harmful substances from industrial wastewater streams to meet regulatory standards and protect the environment. This process typically includes physical, chemical, and biological treatment methods tailored to specific industrial processes and pollutants. By effectively pre-treating industrial wastewater, we can safeguard water quality, prevent damage to treatment infrastructure, and ensure the overall health of ecosystems downstream.
