This gas detector utilizes imported electrochemical sensors and catalytic combustion sensors, combined with microcontroller technology, to detect the concentration of specific gases in the environment. The sensors convert gas concentration signals into electrical signals, which are processed by a 24-bit ADC data acquisition chip and a high-precision microprocessor, ultimately displaying accurate concentration values on the screen. The built-in air pump enables active sampling, ensuring real-time and accurate detection.
Industrial environment, special environment
1. Power on and start the instrument. 2. Set parameters such as detection mode, storage mode, display mode, and air pump mode as needed. 3. Select or switch concentration units such as PPM, %VOL, mg/m³, etc. 4. Perform gas detection; the instrument will display real-time concentration values and graphs. 5. Data is automatically stored and can be viewed or exported through the instrument. 6. Power off the instrument after completing the detection.
• Ensure the instrument is fully charged before use. • Select appropriate sensors and dust filters based on the testing environment. • Regularly calibrate the instrument to ensure measurement accuracy. • Avoid using the instrument in environments with strong electrostatic or magnetic interference. • The instrument features waterproof and dustproof design, but prolonged immersion or extreme conditions should still be avoided. • Alarm thresholds can be set as needed, and the instrument will emit audible and visual alerts when concentration exceeds the limit.
