TC-120F Environmental Air Flow Particle Sampler Product Introduction: This instrument uses filter membrane weighing method to capture total suspended particles (such as TSP, PM10, PM2.5, etc.) in the ambient atmosphere. It is widely used in environmental protection, occupational health, factories and mines, colleges and universities, scientific research and other institutions. 2、 The TC-120F ambient air flow particulate matter sampler adopts biao zhunJJG 943-2011 "Total Suspended Particulate Matter Sampler" HJ/T 374-2007 "Technical Requirements and Testing Methods for Total Suspended Particulate Matter Sampler" HJ 618-2011 "Determination of Weight Method for PM10 and PM2.5 in Environmental Air" HJ 93-2013 "Technical Requirements and Testing Methods for Environmental Air Particulate Matter (PM10 and PM2.5) Sampler" Q/0213TWB 001-2014. The main feature is the use of brushless motor, which can work continuously for a long time; Electronic flowmeter, constant current sampling; Equipped with a real-time clock, it can be set for timed sampling and multiple sampling at equal intervals; The TSP/PM10/PM5/PM2.5 sampling heads are made of aluminum alloy material and have anti-static adsorption properties; Automatic measurement of temperature and air pressure, automatic calculation of standard sampling volume; Small size, light weight, easy to carry; Large sized Chinese dot matrix LCD display screen; Automatically adjust the contrast of the LCD screen with different temperatures, and can work normally at minus 20 degrees Celsius; Power off protection function, automatic sampling of incoming calls; Sampling data can be printed or exported from a USB drive; Can be connected to an external portable AC/DC power supply for field sampling. 4、 Technical indicators
