Automotive Emission Analyzer NHA-506
Product Name: Automotive Emission Analyzer NHA-506
Part No.: YH032
Net Weight: 15KG
Main functions and character:
1. Measure concentration of HC, CO, CO , O and NO
contained in exhaust gases from gasoline engine of
vehicles. Advanced NDIR (non-Dispersive Infrared)
analysis technology is used to measure HC, CO, CO 2
and the newest generation of electrochemical technology is adopted to measure O and NO .
2. Designed with LCD screen for easier setting and operation.
3. Automatic calculation and display of A/F (air-fuel-ratio) λ and Lambda air ratio .
4. Emissions from vehicle engine fuels of CNG, LPG and
Ethanol gasoline can be measured.
5. Small Size, light weight and most convenient for carry.
6. Designed with inductive clip-on pickup sensor for RPM measurement.
7. Designed with oil temperature measurement probe.
8. Designed with RS-232C digital serial interface.
9. 200 groups of measurement data storage and review.
10, n compliance with accuracy requirement of ISO 3930 or OIML R99 Class Ⅰ.
