Ra-COMBO - At-Line Analyzer BOD & Toxicity

The unique design of the Ra-COMBO At-line Analyzer overcomes the disadvantages of other analyzer designs using two oxygen sensors. Instead, the respiration rate measurement used is a patented technology using a single DO-electrode. Today, the respiration technology used knows many references, either in a laboratory environment or in processes.

• Toxicity assessment of incoming wastewater
• Tankcleaning companies
• BODst (short-term BOD) measurement of waste water treatment plant
• Simulation of treatment processes
• Research ends

• Use of real sludge from WWTP for measurement
• Measurement at same pH as WWTP
• Measurement at same temperature as WWTP
• Direct BODst related measurement by using respiration rate instead of oxygen concentration

Human interface: 10.4' color touch screen with excellent viewing angle and graphics. Can remotely be taken over by LAN ethernet software (VNC).

Visualization of the BOD and respiration activity in real-time

Standard auto-cleaning

First class and robust moving components such as low-speed peristaltic pumps and patented single O2 electrode Respiration Module.
Incorporated industrial PC with result & alarm data export (1000 results including sample stream, date, time)

Multifunctional sealed USB port on left side of the housing (result download, program upload, reporting)

Communication: active 4 - 20 mA, Ethernet, RS232, TCP-IP

Weight: 40 kg (107 lbs.)

This system is also available as an on-line analyzer for process ends. Please check our On-line Analyzers Suite.
