Combining accurate dissolved oxygen measurement with sensor self-cleaning and intelligent communications, the Triton DO8 Self-Cleaning Dissolved Oxygen Monitoring System from Electro-Chemical Devices (ECD) features the Triton DO8 Sensor, the AC10 Air Blast Spray Cleaner and the C-22 Controller.
The Triton DO8 Sensor features a maximum error rate of less than 2 percent, repeatability of ±0.5 percent and resolution of 0.01 ppm or 0.01 percent saturation. It operates over a wide measurement range with three different outputs from 0 to 20 mg/l (0-20 ppm), 0-200 percent saturation or 0-500 hPa. It is designed to withstand ambient temperatures from -20 to 60°C and records measurements at temperatures from -5 to 50°C. It withstands pressures up to a maximum of 10 bar.
The AC10 Air Blast Spray Cleaner is available as either a single or dual channel system. It uses pressurized air to generate an area of high turbulence in the water surrounding the measurement end of the sensor. It is housed in a rugged, corrosion resistant, fiberglass reinforced polyester enclosure. Installation options for the AC10 include wall mounting or an optional 2-inch handrail mounting system.
The Triton DO8 Sensor utilizes digital communications to send DO data to ECD’s C-22 Controller, which provides a 4-20mA output signal to a water treatment plant’s control room. The RS-485 digital signal is nearly immune to common EMI/RFI noise that is typically a problem in many plant environments.
