Model T200U-NOy Option Manual Addendum

5.1 Calibration or Cal Check Procedure

Calibration of the analyzer can be checked or adjusted using gas introduced through the CAL IN (3) port on the 501Y rear panel. The calibration gas is routed to a tee fitting (see CAL IN (6) in Figure 4), near the sample inlet on the external Converter assembly.

Since the zero gas concentration is defined as 0 ppb, it is not necessary to enter the expected zero value. Table 3 details the zero calibration procedure.

1.

Press CAL

The analyzer enters the calibrate mode.

 

 

 

2.

Wait For Stability

Wait for reading to stabilize at zero value.

 

Type STB < 0.1 PPB

 

 

 

 

3.

Press ZERO

If you change your mind after pressing ZERO, you can still

 

 

press EXIT here without zeroing the instrument.

4.

Press ENTR

Pressing ENTR actually changes the calculation equations.

 

 

 

5.

Press EXIT

The analyzer returns to sampling. Immediately after

 

 

calibration, data is not added to the DAS averages.

1.

Press

This menu sequence causes the analyzer to prompt for the

 

CAL>CONC>NOy

expected NOy concentration.

 

 

Enter the NOy span concentration value by pressing the

 

 

applicable touchscreen buttons to set the expected value.

2.

Press ENTR

ENTR stores the expected NOy span value.

 

 

 

3.

Press

Now enter the expected NO span concentration as in step one.

 

CAL>CONC>NO

 

4.

Press ENTR

Pressing ENTR stores the NO span value and returns the

 

 

prompt to the CONC menu.

5.

Press EXIT

Returns instrument to SAMPLE mode.

 

 

 

 

 

 

 

 

If desired, compensation for converter efficiency (CE) can be included in the NOy concentration calculation. Prior to calibration, the converter efficiency should either be set to 1.0 or determined per the procedure in the T200 manual.

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.
