Flue Gas Oxygen analyzer with automatic calibration and Modbus output

The WDG 1200 Insitu and the WDG 1210 Insitu are rugged, reliable flue gas analyzers for net oxygen that use industry-proven zirconium oxide sensor technology. The outer probe tube is 310 stainless steel so no abrasion shield is needed for most applications. The controller features precision temperature control for optimum stability, built-in diagnostics, and over-temperature protection. Modbus and 4-20 mA outputs are standard; automatic calibration is available. The unique sensor design allows the entire sensor assembly, including the heater, to be removed without disturbing the outer protection tube which remains in the process. This makes field service fast and easy, and because there is no need to return the probe to the factory for repair, there’s no expensive downtime.
