The product complies with GB3847-2005 Limits and Measurement Methods for Smoke Emissions from Compression Ignition Engines and Compression Ignition Engine Vehicles; HJ/T 395-2007 Technical Requirements for Free Acceleration Smoke Measurement Equipment for Compression Ignition Engine Vehicles; JJG976-2010 Verification Regulation for Transmissive Opacimeters; Enterprise standard Q/WTH 42-2024 TH-502 Intelligent Diesel Engine Opacity Analyzer.
Application Scope
The TH-502 intelligent diesel engine opacity analyzer uses split-flow transmissive optical principle to test smoke emission content from vehicles powered by diesel engines. The instrument is designed and produced in accordance with GB3847-2005 and HJ/T395-2007 technical requirements for free acceleration smoke measurement equipment for compression ignition engine vehicles. Key components are all original imported parts, featuring high measurement accuracy, good stability, and long service life. It is the preferred product for automobile manufacturers, auto repair shops, vehicle inspection centers, and environmental protection monitoring units.
Instrument Features
•Easy Operation: Large color LCD screen display, full Chinese interactive interface with operation prompts, human-machine dialogue, strong operational logic;
•Split Structure: Measurement unit separated from display unit; more hygienic, environmentally friendly, and easy to operate;
•Long Service Life: Measurement system uses “dual air curtain” technology to better protect the optical system from contamination by measured exhaust gas;
•Detection chamber uses constant temperature control to avoid influence on measurement results from water vapor condensation and temperature changes;
•Measurement Results: Displays both opacity and light absorption coefficient, intuitive and convenient;
•Measurement Functions: Features free acceleration test measurement and real-time detection functions, automatically processes measurement data and displays results;
•Safer Data: Internal storage of 50-200 sets of test data; can be queried or printed at any time;
•Wide Measurement Range: Wide smoke measurement range, measuring both smoke opacity and obscuration, from zero to full black (zero opacity indicates no smoke in the sample chamber, full black indicates complete blockage of the light path);
•Data Printing: Optional Bluetooth printer for wireless printing (default wired micro printer);
•Power Supply Mode: AC/DC dual use, when using DC power, directly connect to vehicle DC24V battery.
