5.0CALIBRATION AND CAL CHECKS

Unlike most NOx analyzers, the T200U-NOy does not have a sample inlet port on its rear panel. The sample inlet is located on the external Converter.

Follow the steps in the T200U manual to:

Enter the expected NO and NOy span gas concentrations in the analyzer.

Do the zero calibration procedure Do the span calibration procedure

The analyzer always routes the zero/span gas through the external Converter. In standard configuration, the calibration gas needs to be input at the CAL IN (3) port of the 501Y bypass pump. In all cases, the calibration gas delivered must be under a small amount of pressure (2-5 psig) to overcome the resistance of the tubing.

NOTE

There must be no venting of the Zero or Span gas to atmosphere prior to the analyzer. The gases actually vent at the external Converter.

Calibration gas must be provided for both the 501Y bypass system and the analyzer. Flow requirements are 0.80 LPM for NO bypass, 0.80 LPM for NOy bypass and 1 LPM for the analyzer. Calibration gas flow must be in sufficient excess (~4 LPM) to prevent any ambient air from entering the sample inlet of the external Converter.

The maximum 50 ft length of tubing between the 501Y and the remote Converter has been proven to generate too much backpressure for some brands of calibrators. Teledyne calibrators are designed to overcome this potential issue.

We strongly recommend that span calibration be done with NO span gas. Span checks can be done with one of: NO only, NO2 only, or a mixture of NO and NO2 (GPT).

Zero air used for all calibration procedures, including GPT, should have <1 ppt NO and NO2, less than 1 ppt of major interferents such as SO2, NH3, hydrocarbons and a dew point of -5oC or less. The calibration gasses should be from a reliable supplier, since the quality of the tank concentration values ultimately determines the accuracy of the analyzer.

NOTE

The T200U-NOy does NOT have equivalency approval.

T200U-NOy specifications

The Teledyne T200U-NOy is an advanced gas analyzer specifically designed to measure nitrogen oxides (NOx) concentrations in a variety of applications, including industrial emissions monitoring, environmental assessments, and combustion control. It builds upon Teledyne's legacy of producing high-quality analytical instruments, making it a reliable choice for professionals in the field.

One of the main features of the T200U-NOy is its ability to measure multiple nitrogen oxides, including nitrogen dioxide (NO2), nitric oxide (NO), and nitrous oxide (N2O), which are critical for understanding and managing air quality and combustion efficiency. The instrument offers high sensitivity and accuracy, allowing for real-time monitoring of NOx levels with a detection limit that suits stringent regulatory requirements.

The T200U-NOy utilizes advanced chemiluminescence technology for NO measurement, which is widely recognized for its reliability and precision. This method involves the reaction of NO with ozone (O3) to produce excited NO2, which subsequently releases light as it returns to a lower energy state. The intensity of this light is measured and directly correlates to the concentration of NO in the sample, providing highly accurate readings.

In addition to its core measurement capabilities, the T200U-NOy is equipped with a variety of features that enhance its functionality. Its user-friendly interface allows for easy configuration and data retrieval, making it accessible to a wide range of users, from seasoned professionals to those new to gas analysis. The device supports multiple communication protocols, including analog and digital outputs, facilitating integration into existing monitoring systems.

The T200U-NOy is constructed with robust materials designed to withstand harsh industrial environments, ensuring longevity and reliability. It also includes features for easy maintenance, such as user-replaceable parts, which can significantly reduce downtime.

Overall, the Teledyne T200U-NOy stands out in the field of gas analyzers, combining cutting-edge measurement technologies with user-centric features and robust construction. Its comprehensive capabilities make it an essential tool for accurately monitoring nitrogen oxides, ultimately contributing to better environmental protection and compliance with air quality regulations.
