HL-80A Ringman Blackness Meter（Digital Smoke Measuring Telescope
Type HL-80A Ringelemann Nigrometer (Digital Measuring
Smoke Telescope）
Instrument Introduction:
The Ringman Blackness Meter (Digital Smoke Telescope) shrinks the standard Ringman smoke concentration map onto a piece of glass to monitor the blackness of smoke. By directly comparing the smoke image seen in the telescope eyepiece or captured by a digital camera with the Ringman smoke concentration map, the blackness level of the smoke can be determined. It makes the testing of smoke blackness fast and easy, and improves the accuracy of monitoring work. Therefore, this instrument can be widely used in the determination of smoke blackness by environmental protection departments and industrial and mining enterprises in various regions.
