Features
High-Precision Testing:The AUTOOL PT670 features a measurement accuracy of ±1.0% FS and is suitable for most vehicle models on the market, providing simple, efficient, and accurate testing.
Fast Fault Location:No need to remove the catalytic converter for preliminary blockage diagnosis, significantly improving diagnostic efficiency.
Data-Based Precise Diagnosis:Uses objective pressure data instead of experience-based judgment, helping avoid reading errors caused by the fluctuation of traditional mechanical gauges.
Reduced Repair Costs:Helps identify abnormal exhaust back pressure at an early stage, reducing unnecessary DPF replacement and the risk of repeated repairs.
Exhaust System Blockage:When the exhaust pipe or catalytic converter becomes blocked, exhaust flow is restricted, resulting in reduced engine performance. The back pressure gauge accurately measures exhaust back pressure to help determine whether the exhaust system is blocked and assess the severity of the blockage, helping address problems such as reduced power, increased fuel consumption, and unstable idling.
Exhaust Valve and Catalytic Converter Fault Diagnosis:Faults in the exhaust valve or catalytic converter can cause excessive exhaust back pressure and affect normal engine operation. The back pressure gauge can help accurately diagnose these conditions and identify issues associated with illuminated warning lights, including P0420 – Catalyst System Efficiency Below Threshold.
Optimized Engine Performance:High exhaust back pressure can restrict the engine’s intake and exhaust flow, affecting engine efficiency and power output. By measuring exhaust back pressure, the gauge helps evaluate and optimize the exhaust system to support proper engine operation.
Exhaust System Inspection and Maintenance:Regular exhaust system inspection and maintenance are important for long-term vehicle operation. Periodic exhaust back pressure testing can help identify potential exhaust system problems so they can be repaired or replaced in time, helping prevent engine problems caused by restricted exhaust flow.
Auxiliary Emissions Testing:Abnormal exhaust back pressure may contribute to excessive vehicle emissions or emissions inspection failure. The exhaust back pressure gauge provides accurate data to help evaluate the condition of the emissions system and help determine whether the vehicle meets applicable emissions standards.
2.8-Inch Backlit Display:The LCD screen displays measurement values in real time with clear and bright readings, with values displayed to two decimal places.
High-Temperature-Resistant Hose:The 140 cm hose is made of high-quality heat-resistant material, providing safe and durable performance in various testing environments.
Copper Riveted Fittings:The fittings feature a durable, wear-resistant construction with excellent oxidation resistance for long-term reliable use.
One-Touch Unit Switching:The AUTOOL PT670 supports multiple unit options, including pressure units (mbar, inHg, psi, Torr) and temperature units (°C). There is no need to manually calculate conversion values. Simply switch to the desired unit to read measurement directly.
The temperature unit also provides a real-time reference for monitoring the testing environment, improving testing efficiency, safety, and convenience.
Data Hold Function:The AUTOOL PT670 supports one-touch data hold, data release, and zeroing operations. This helps prevent reading fluctuations caused by external factors such as hand movement and environmental vibration, making it easier to record measurements or compare them with subsequent test results.
3-Year Warranty:For equipment damage caused by non-human factors, AUTOOL provides free replacement parts within three years. If you encounter any issues, please contact us at any time. We will respond promptly within 24 hours. We are committed to taking responsibility for our products, customers, and partners.
