Handheld LD-5H laserDust analyzerThe test result can be obtained in 1 minute, the cutting head can be replaced, and the national measuring instrument license has been obtained It has multiple functions such as continuous monitoring of particulate matter concentration, timed sampling, and alarm for excessive dust concentration.

The measurement range of the handheld LD-5H laser dust analyzer is0.01～100 mg/m³If you need more measurement results, you can choose the modelLD-5H（0.001～10 mg/m³）.Laser dust analyzerIt is a light scattering rapid dust analyzer using a laser micro light source, which can directly read the mass concentration of particulate matter

Handheld design, can carry various testing sites, can meet various testing needs such as indoor and outdoor environment testing, environmental protection, production environment, health and disease control, etc.

Handheld LD-5H laser dust analyzerThere are PM10, PM5, PM2.5, PM1.0, and TSP cutters available for selection The instrument adopts a powerful suction pump, making it more suitable for detecting the concentration of PM10 inhalable particulate matter at the central air conditioning exhaust port that requires a longer sampling tube, and monitoring the concentration of inhalable dust PM2.5.

To purchase a laser dust analyzer, please contact us directly. All kinds of well-known domestic and foreign brands are available. Our company can also provide measurement and inspection services on behalf of others, free of charge.
