Which exhaust gases can the SV-5Q analyzer measure?
The analyzer measures the concentration of HC, CO, and CO₂ directly in vehicle exhaust gas using the Non-Dispersive Infra-Red (NDIR) method. Additionally, it detects NO and O₂ levels using an electrochemical sensor, allowing it to calculate the excess air coefficient (λ).
Does this emission tester meet international accuracy standards?
Yes, it satisfies GB18285-2005 requirements. It achieves the national standard ISO3930 and international OIML R99 Class I accuracy levels.
Can the analyzer test vehicles using alternative fuels?
Yes. The device is versatile and designed to measure exhaust emissions from vehicles using three types of fuel: natural gas (CNG), liquefied petroleum gas (LPG), and standard gasoline.
How long is the startup preheating time for the device?
The system requires a startup preheating time of approximately 10 minutes to stabilize the components and ensure highly accurate measurements.
Does the device support data logging and immediate reporting?
Yes. It features built-in storage capable of saving up to 500 groups of exhaust gas measurements. An integrated micro-printer is included to print test results directly on-site.
