Features: Portable integrated structure design; The smoke can be measured by the split sampling technology, the acceleration, deceleration and steady speed of the diesel engine; Automatic linear linearization processing, showing opacity N, light absorption coefficient K and corresponding filter paper smoke value SF; High brightness digital display; Protect the optical system from contamination with “air curtain” technology; Automatic constant temperature control of the detection room can prevent condensation and affect test accuracy; With automatic time display, optional speed measurement and oil temperature measurement; The unit where the automatic fault diagnosis display is displayed; With built-in printer (or RS232/RS485 interface or analog interface). Meet the technical requirements of ISO11614 and GB3847-2005. Technical Parameters: Measurement range opacity N: 0 to 100% (equivalent smoke value 0 to 10FSN) Light absorption coefficient K: 0 ~ 16.06m-1 Speed: 0-9990rpm Oil temperature: 0-150°C Indication error ≤±2% (measured value) Stability Automatic zero calibration, moment drift ≤±1%/4h Repeatability repeat error ≤±1% The resolution N is 0.1%, K is 0.01m-1, the rotation speed is 10rpm, and the oil temperature is 0.1°C. Output mode Digital direct reading display, can be attached to the printer to print the smoke density (darkness) maximum, test Time, date, etc. Attachable interface to network with computer Measuring chamber temperature 70 ° C (automatic constant temperature), when the temperature error ≥ ± 10%, the temperature and error indicator lights Environmental conditions Temperature -5 ~ 50 ° C, relative humidity ≤ 90% Power supply AC100-240V 50/60Hz power consumption 150VA Dimensions (including bracket) 160mm (deep) × 400mm (width) × 480mm (height) Weight about 8kg
