How to Use the Laser Methane Detector?

Ⅰ. The basic principle of the laser methane detector

The laser methane detector is a device that uses laser technology to measure the atmospheric methane concentration over a long distance. The basic principle is to use the laser beam to pass through the atmosphere, which is scattered back after a certain distance, and the concentration of methane is calculated by receiving the change in the irradiation power of the scattered light. The device has the advantages of non-contact, high sensitivity, fast response and long-distance measurement, and is widely used in environmental monitoring and gas detection.

Ⅱ. Advantages of the laser methane detector

The drone laser methane detector is a lightweight drone-mounted device launched to adapt to drones. It has high sensitivity, fast detection response speed, reduced cost, and reduced operational risks.

Laser methane gas detector based on semiconductor laser absorption spectroscopy technology. It can detect parameters such as methane gas concentration in various environments with high accuracy, fast response speed, high reliability and low operating cost.

Compared with fixed gas leak detectors, drones are not only a more cost-effective way to solve the problem, but also a more effective way.

With high sensitivity, the laser methane gas detector can even pick up tiny leaks from a height of 80 meters. The sensor is only sensitive to methane, so it is impossible to produce false readings due to the presence of other gases. In addition, the drone equipped with a methane detector can penetrate into small spaces that cannot be entered by staff or areas with a high risk index, ensuring the personal safety of staff. The CH-4 laser methane detector has become a safe, efficient and accurate productivity tool in the process of natural gas inspection operations, greatly reducing the workload of inspection workers.

III. Usage

  1. Equipment preparation

The laser methane detector needs to be measured in an open field to avoid interference factors such as buildings, cars, chimneys and high-voltage lines. At the same time, it is necessary to ensure that the equipment is stable and not disturbed during use.

  1. System debugging and calibration

Before using the laser methane detector, system debugging and calibration are required. First, perform equipment self-test and data transmission to ensure that the equipment is in normal working condition. Then, according to the measurement requirements, select appropriate parameters such as laser wavelength, laser power and data acquisition time, and calibrate the equipment.

  1. Measurement process

The following points should be noted during the measurement process:

(1) Preheat the equipment to ensure that the laser and detector are in a stable state;

(2) Find a suitable measurement point and mark the position;

(3) When measuring, minimize the impact of ambient light and interference signals on the measurement results;

(4) Perform measurements according to the equipment requirements to ensure the accuracy of data collection.

  1. Data processing

The data obtained by the laser methane detector needs to be processed and analyzed. First, the raw data needs to be calibrated and processed, and then the methane concentration is calculated through algorithms and models, and analyzed and studied in combination with other data.

iv. Precautions

The following points should be noted when using the laser methane telemeter:

(1) Regularly inspect and calibrate the equipment to maintain the performance and accuracy of the equipment;

(2) Protect the equipment and prevent damage. Do not expose the equipment to sunlight for a long time or use it in a high temperature or humid environment;

(3) When using the equipment, safety protection and compliance with relevant regulations are required to ensure safety during measurement.


The laser methane detector is a very efficient and accurate measuring device. Its use is relatively simple, but some operating details and precautions need to be paid attention to to ensure the accuracy and reliability of the measurement results. This device is widely used in environmental monitoring and gas detection, and is of great significance to protecting the environment and people’s health.
