NHA-506EN Automotive Emission Analyzer (5-Gas, Portable)

NHA-506EN Automotive Emission Analyzer

The NHA-506EN Automotive Emission Analyzer is a portable, high-accuracy 5-gas exhaust emission testing solution designed for gasoline engine vehicles. It delivers fast, reliable measurements and is ideal for automotive workshops, inspection stations, and professional technicians.

Gas Measurement Capability

The analyzer measures the following exhaust gases:

• HC (Hydrocarbons, n-Hexane)

• CO (Carbon Monoxide)

• CO₂ (Carbon Dioxide)

• O₂ (Oxygen)

• NO (Nitric Oxide)

It also automatically calculates AFR (Air-Fuel Ratio) and Lambda (λ) values.

Measurement Technology

• Uses NDIR (Non-Dispersive Infrared) technology for HC, CO, and CO₂ analysis

• Utilizes a new-generation electrochemical sensor for precise NO detection

• Designed for stable and accurate exhaust gas analysis

Measurement Ranges

• HC: 0 – 9,999 ppm (n-Hexane)

• CO: 0 – 10 %

• CO₂: 0 – 18 %

• O₂: 0 – 25 %

• NO: 0 – 5,000 ppm

Measurement Accuracy

• HC: ±12 ppm (abs.) 0–2,000 ppm | ±5% (rel.) above 2,000 ppm

• CO: ±0.06% (abs.) 0–1% | ±5% (rel.) above 1%

• CO₂: ±0.5% (abs.)

• O₂: ±0.5% (abs.)

• NO: ±25 ppm (abs.) or ±4% (rel.)
