Introduction:

The instrument has two kinds of fully automatic opaque smoke meters that can be directly powered. It is portable and designed for easy portability. It is especially suitable for environmental monitoring, public security, traffic control departments for road inspection and sampling, industrial and mining enterprises in the wild and remote areas. It can be used; it meets the requirements specified in Appendix G and H of GB3847-2005 "Exhaust smoke emission limits and measurement methods for automotive compression ignition engines and compression ignition engines", and refers to the traffic industry standard JT/T506 of the People's Republic of China. -2004 Designed for standards, the smoke for steady-state and transition phenomena can be measured. And meet the test standards of GB/T 3871.13-2006.

Features:

1. The integrated portable smoke meter can continuously measure the smoke when the machine (vehicle) accelerates, decelerates and stabilizes.

2. Large LCD screen direct reading display, full Chinese prompt menu, and waveform display of accelerated measurement process, very intuitive.

3. There are accelerometer, instantaneous measurement, and steady state measurement modes to choose from.

4. The microprocessor is included in the machine, and the data can be calculated and processed in real time. It is directly displayed by the front panel, and can also be printed by the internal printer, or RS232/RS485 interface.

5. With automatic zero adjustment, with self-diagnosis function, when the instrument is faulty or the light path is polluted, there will be a prompt at the bottom of the screen, which is convenient for the user to deal with in time.

6. The machine has a time function, which can adjust, display and print out the year, month, day, hour and minute. It can also store the measurement data of 2000 groups of locomotives, and has the license plate number input function for later investigation.

7. The light source uses a light emitting diode and the detector uses a photodiode. Optical characteristics meet the requirements of GB 3847-2005.

8. The measuring chamber is automatically controlled to adjust the temperature and temperature to prevent condensation and residence of moisture in the exhaust gas, which affects the accuracy of the measurement results.

9. The special air curtain type special protection technology carefully protects and maintains the self-cleaning of the measuring optical lens to ensure that the optical system is protected from the pollution of the exhaust smoke when it is continuously tested.

10. Optional speed measurement and oil temperature measurement.

Technical Parameters:

1. Measurement range: opacity N: 0-100%

Light absorption coefficient K: 0-106.06m-1

Speed: 0-9990rpm Oil temperature: 0-150°C

2. Resolution: N is 0.1%, K is 0.01m-1, RPM is 10rpm, OIL TEMP is 0.1°C

3. Measuring circuit response time 1s ± 0.1s

4. Indication error: ≤±2%

5. Measurement room size: Physical channel length: 244mm

Optical channel length: 215mm

Sampling indoor diameter: Φ20 mm

6. Heating time: 3-5 minutes

7. Output mode: The LCD large-screen LCD display controlled by the microcomputer can be attached to the printer to print the maximum smoke (darkness) and the average of several measurements, test time and date. Interfaces can also be networked with computers.

8. Temperature alarm: The temperature of the measurement room is about 72 °C. When the temperature exceeds 99 °C, there is a temperature out of control alarm. When the temperature is lower than 60 °C, the standby state cannot be reached.

9. Sampling probe: The inner diameter of the probe is Φ14.2mm. The company can customize the special requirements such as the inner diameter of the probe.
