• Useful for monitoring temperature and control of DO in waste water treatment and aquaculture applications. Use with valves, blowers or aerators to ensure proper system operation.
• With a wide measuring range of 0 to 20 ppm or 0 to 200 % saturation, Alpha DO 2000 controller/transmitter is ideal for use in a variety of applications, ranging from water treatment and monitoring to pharmaceutical and food processing. Meter comes in both Galvanic and Amperometric versions.
• Quick, easy calibration using atmospheric air as calibration media for 100 % air saturation
• Pressure, Salinity and Automatic Temperature Compensation
