Portable TDLAS NH3 GAS Analyzer H2S HCL HF CO ppm Range High Accuracy High Resolution
A portable TDLAS NH3 gas analyzer is a handheld or portable gas analyzer that utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology specifically designed for the analysis of ammonia (NH3) gas. Ammonia is commonly found in various industrial processes, agricultural applications, and environmental monitoring, where accurate and reliable measurement of NH3 concentration is important.
Here are some key features and capabilities of a portable TDLAS NH3
gas analyzer:
1. Measurement Principle: The analyzer utilizes TDLAS technology,
which uses a laser beam at a specific wavelength that matches the
absorption characteristics of ammonia gas. As the laser beam passes
through the gas sample, it interacts with the NH3 molecules, and
the analyzer measures the amount of light absorbed, enabling the
determination of NH3 concentration.
2. Portable and Handheld Design: Portable TDLAS NH3 analyzers are
designed to be lightweight, compact, and easily transportable. They
are typically battery-powered and equipped with a handheld
interface or display, allowing for on-site measurements and easy
operation by field personnel.
3. High Sensitivity and Selectivity: TDLAS technology offers high
sensitivity, allowing for accurate and precise measurements of NH3
concentrations even at low levels. The laser wavelength can be
tuned to match the specific absorption lines of NH3, providing
excellent selectivity and minimizing interference from other gases
present in the sample.
4. Real-time Monitoring: Portable TDLAS NH3 analyzers provide
real-time measurements, enabling immediate detection and monitoring
of NH3 levels. This capability is particularly valuable in
applications such as environmental monitoring, agricultural
operations, and industrial processes where rapid response is
essential.
5. Wide Measurement Range: Portable TDLAS NH3 analyzers typically
offer a wide measurement range to accommodate different
concentration levels of NH3. The measurement range can vary
depending on the specific instrument, but it can span from low
parts-per-billion (ppb) levels to high parts-per-million (ppm)
concentrations.
6. Data Logging and Connectivity: Many portable TDLAS NH3 analyzers
come equipped with data logging capabilities, allowing for the
storage and retrieval of measurement data for further analysis and
reporting. Some models may also offer connectivity options like
USB, Bluetooth, or wireless communication for data transfer and
remote monitoring.
7. Safety Features: Portable TDLAS NH3 analyzers often include
safety features such as alarms and visual indicators to alert the
user when NH3 concentrations exceed predefined thresholds. These
features help ensure the safety of the operator and provide an
early warning of potentially hazardous conditions.
It's important to note that the specific features, measurement
range, and performance characteristics can vary among different
models and manufacturers of portable TDLAS NH3 analyzers. It's
recommended to consult the product specifications and user manual
provided by the manufacturer to understand the capabilities and
limitations of a particular instrument for your specific NH3
analysis requirements.

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.
