Details
The analyzer adopts the NDIR principle to measure the content of CO, HC and CO2, and the electrochemistry principle to measure the content of NO and O2 in the exhaust smoke from the gasoline engine, and finally obtain the excess air coefficient λ based on the content of CO, CO2, HC and O2. Capable of performing multi-mode dual-speed idle test on gasoline, natural gas (LNG/CNG), liquefied petroleum gas (LPG), ethanol gasoline, and various fuel-powered vehicles.
Options
- Bluetooth micro printer: print real-time results as well as history record.
- Photo identification function for driving license: which automatically identifies and inputs vehicle information by taking photos from the tablet, is optional to be added in the tablet.
- Lithium battery of high capacity: possible to be continuously operated for 6h from full power under normal outdoor temperature. It's also available to be operated by connecting with charger. (Note: Due to the characteristics of lithium battery, operating time would be relatively decreased under low temperature.)
- Built-in high-performance and low-power WIFI module: the connection distance with tablet can be over 15m.
Features
- Higher precision: complies with the latest regulations for Class 00 instruments according to OIML R99/2000(E), ISO 3930, and JJG 688.
- Cutting-edge technologies and key components, equipped with high-performance microprocessor and LCD screen;
- Lightweight, compact portable and practical, allows for quick warm-up and rapid measurement.
- NHA-605P features a handheld design with a tablet, offering dual power options: DC 220V and a built-in lithium battery (5-6 hours of battery life).
Applications
It is applicable for environmental protection departments, vehicle inspection and detection station, vehicle manufacturers, mobile exhaust gas inspection station, etc.
