The Wohler A 500 Commercial/Industrial O2/CO Combustion and Emissions Analyzer sets the standards in Flue Gas Analysis. Based on proven technology, the Wohler A500 Commercial/Industrial O2/CO Combustion and Emissions Analyzer combines simple “Touch-Screen” operation with a full featured commercial and light industrial grade analyzer. The Wohler A-500 is the ideal tool for the service technician who needs to determine CO safety, combustion efficiency and emissions compliance.

By switching the ON/OFF button the A:500 calibrates automatically and shows up to 12 values on the touch screen display. With the unique R.R.T technology values are continuously shown on the X-Large LCD screen. All functions can be reached easily; the fuel selection, the graphic mode, the parameter input, the printout, and the data administration. The analyzer comes standard with advanced communications capabilities and data storage for more than 800 complete combustion records. Standard AA batteries or rechargeable NiMH batteries will provide up to 12h operation time. With up to 4 electrochemical sensors, the port to connect a peltier cooler or various temperature probes, the A/500 offers an enormous range of application capabilities.

The condensate trap system consisting of 4 easy to reach filters protects the sensors from humidity and smoke. The automatic clean out pump protects the sensors during high CO situations. Electronic sensor life self-diagnostics eliminate on the job downtime by letting you know when sensors will need to be changed, before you get on the job. Precalibrated field replaceable "smart sensors" eliminate the need for costly, time consuming service center calibrations.
