Teledyne Instruments 702/501NH3/201E

Ammonia Gas Analyzer Model 201E Chemiluminescence NH3 Analyzer with 501NH3 Converter and 702 Precision Calibrator. The Model 201E operation sample gas is passed through the 501NH converter which converts NH3 and other compounds to NO producing the total oxides of nitrogen (TNx), in the next cycle the sample is routed through a molybdenum converter which converts nitrogen oxides (less NHE3) to NO producing the Tn reading. The difference between these readings (TNX - TN = NH3) provides a reading proportional to the NH3 concentration. The analyzer software represents these values in the readout and independent outputs are available of each of these values. 0 to 50 ppb to 0 to 2,000 ppb user selectable. Multitasking software allows viewing of test variables during operation. Continuous self checking with warning alarms. The Model 702 Precision Calibrator provides an ideal means of calibrating ambient air analyzers in an economical, high-value manner. Two channels of source gas. Remote control with contact closures. Digital status output. Temperature controlled flow control system to provide stable flow. 115V, 60 Hz, CE. Systems not calibrated, basic testing only.
