Portable TDLAS Gas Analyzer NH3 H2S HCL HF CO Ppm Range High Accuracy High Resolution

A portable TDLAS gas analyzer refers to a gas analysis instrument that utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology and is designed for portable or handheld use. TDLAS is a highly accurate and sensitive optical measurement technique commonly used for trace gas analysis.

Here's how a portable TDLAS gas analyzer typically works:

1. Laser Source: The instrument consists of a laser diode that emits a narrow-band laser beam at a specific wavelength. The laser wavelength is selected to match the absorption characteristics of the gas to be analyzed.

2. Gas Sample Interaction: The laser beam is directed through the gas sample, typically in a closed sampling cell or probe. The gas sample may be drawn into the cell using a built-in pump or through a sampling line.

3. Absorption Measurement: As the laser beam passes through the gas sample, it interacts with the target gas molecules. The gas molecules absorb light at specific wavelengths, which is directly proportional to their concentration in the gas sample. The analyzer measures the amount of light that is absorbed by the gas sample.

4. Detection and Analysis: The light transmitted through the gas sample is detected by a photodetector, which converts the light intensity into an electrical signal. This signal is then processed by the analyzer's electronics to determine the gas concentration based on the absorption characteristics and known calibration parameters.

5. Display and Data Storage: The analyzed gas concentration data is typically displayed on a built-in screen or interface. Portable TDLAS analyzers often have data logging capabilities, allowing for the storage and retrieval of measurement data for further analysis or reporting.

The portability aspect of these analyzers makes them suitable for various applications, such as industrial emissions monitoring, environmental monitoring, safety and leak detection, and process control. They offer advantages such as high accuracy, real-time measurements, non-invasive sampling, and the ability to measure multiple gas species simultaneously.

It's worth noting that specific features and capabilities may vary among different models and manufacturers of portable TDLAS gas analyzers. Therefore, it's recommended to consult the product documentation or contact the manufacturer for detailed information about a particular instrument.

☑ Applications Process control: SCR, incineration &combustion processes.

Instrument Characteristics

This portable laser gas analyzer has the following key features, including:

☑ Full-temperature high-temperature heat extraction method is adopted, which is not limited by on-site working conditions, wide applicability, and simple to use and maintain;

☑ Using TDLAS high-resolution spectroscopy technology, it can be measured without interference from other gases, which can effectively reduce the influence of dust or background gas. This feature has obvious advantages compared with other analytical methods.

☑ Laser optical spectrum analysis has the advantages of fast response and high sensitivity. In practical applications, the resolution can reach 0.1ppm, which can meet the accuracy requirements of industrial instrument gas component detection.
