Accessoriess
The main accessories of a smoke density tester include the following categories, and their functions are briefly described below:
Smoke Box: As the core component of the tester, it is used to contain the sample and collect the smoke generated during combustion.
Combustion System: Includes main/auxiliary dual burners, nozzles, igniters, etc., used to provide a stable flame to ignite the sample.
Photoelectric Detection System: Composed of a light source (such as a bulb or laser), photodetectors (such as silicon photocells or photomultiplier tubes), filters, etc., used to measure the degree of light attenuation by smoke, thereby calculating smoke density.
Exhaust System: Includes exhaust fans, exhaust ducts, etc., used to exhaust exhaust gases outdoors after the test, maintaining a clean testing environment.
Sample Clamp: Used to fix the sample, ensuring its stability during combustion.
Standard Filter: Used to calibrate the instrument, ensuring the accuracy of measurement results.
Control Software and Data Acquisition System: Used to control the testing process, collect data, and generate test reports.
Other auxiliary accessories: such as power cord, rubber tubing, medium pressure valve, USB flash drive (containing device software program), instruction manual, certificate of conformity, etc.
Test Procedures
The operation method of a smoke density tester includes the following steps:
Installation Check: Ensure the smoke density tester's battery is charged and the sensor is clean. Check if the environmental conditions of the test area meet the requirements.
Parameter Setting: Select the test mode, set the time interval, and determine the test range as needed.
Aiming at the Smoke Source: Aim the tester's sensor at the smoke source or emission source in the test environment, ensuring the sensor can accurately receive the scattered light from smoke particles.
Maintaining a Stable Position: Ensure the accuracy of the test results by avoiding vibration and human interference.
Data Recording: After the test, review the results and record and save the data as needed.
Regular Calibration: Regularly calibrate the smoke density tester to ensure the accuracy of the test data.
Sensor Cleaning: Clean the sensor regularly to prevent dust, oil, or other impurities from affecting the test results.
