Automobile exhaust gas analyzer

Product catalog summary

General Features
The Gasboard 5020 is designed for analyzing exhaust gases from petrol or LPG engines. It measures and displays CO, CO2, NO, HC, O2, oil temperature, and engine RPM. It calculates the air/fuel ratio (Lambda) and performs an automatic leak test of the sampling line. The device supports multiple fuel types including petrol, LPG, and natural gas, and allows for user-specific fuel selection. It includes interfaces for an external oil temperature probe and a tachometer, with measurements based on vibration and noise analysis. Configuration and calibration are managed via a 6-button keypad.

Technical Specifications
The analyser uses non-dispersive infrared (NDIR) detectors for CO, CO2, HC, and electrochemical sensors (ECD) for O2 and NO. It features automatic zero calibration with ambient air and includes a water/dust filter. The device has an integrated printer and data logger via RS232. It operates within an ambient temperature range of 0-40°C, pressure of 86-108 kPa, and relative humidity of 5-85%. The power supply requirement is 220 VAC ± 20% at 50 Hz ± 2%.

Measurement Range and Accuracy
- CO: 0.00 – 10.00% vol, resolution 0.01% vol, absolute error ±0.06%
- HC: 0 – 9999 ppm vol, resolution 1 ppm vol, absolute error ±12 ppm
- CO2: 0.00 – 20.00% vol, resolution 0.01% vol, absolute error ±0.5%
- O2: 0.00 – 25.00% vol, resolution 0.01% vol, absolute error ±0.1%
- NO (optional): 0-5000 ppm, resolution 1 ppm vol, absolute error ±25 ppm
- Lambda display: 0.50 – 2.50, resolution 0.01
The relative error for all components is ±5%, with a repeatability error (RSD) of no more than 2%.

Response and Operational Details
The response time is 10 seconds for NDIR and 30 seconds for ECD. The warm-up time is 10 minutes. The device dimensions are 260×180×360 mm, and it weighs approximately 8 kg.

Panel Structure and Accessories
The analyser includes a front and back panel, sampling probe, sampling pipe, RS232 cable, optional PT 100, optional cigar lighter RPM, and optional vibration RPM.
