The probe has outstanding range and durability, providing excellent performance in both applications. The probe provides a reading completely independent of diffusion rate through its membrane. This independence permits the use of a heavy-duty silicone rubber covering to protect the membrane.
Compensation is provided for the varying solubility of oxygen with temperature.
Calibration is accomplished either by exposure of the probe to air or by comparison with another instrument or standard. For low ppb measurements, zero calibration is also available. DO Analyzer display for configuring an alarm illustrates the convenient menu-driven structure for setup. The down arrow indicates the alarm menu can be scrolled down to show the additional setting for delay. For wastewater aeration control to maximize energy savings, the Series 7020 Dissolved Oxygen Analyzer includes full PID control with either CAT or DAT output.
