ZR-3925 ambient air sampler for semi-volatile organic compounds Introduction: The ZR-3925 ambient air semi-volatile organic compound sampler is a sampler specially designed to collect air fluoride, heavy metals and SVOCs, and can also collect atmospheric particulate matter (TSP, PM10, PM2.5). It is suitable for routine monitoring of aerosols in environmental protection, health, labor, safety supervision, scientific research, education and other departments. Features: 1. The whole machine has excellent waterproof, dustproof and anti-collision performance, and can work normally in rain, snow, dust and severe haze weather; 2. Meet the sampling requirements of glass fiber filter membrane, PUF adsorption resin VOC sampling tank (VOC); nitrocellulose acetate membrane (fluoride); vinyl chloride membrane (heavy metal), PTFE (polytetrafluoroethylene) and quartz filter membrane sampling requirements ; 3. Adopt 5-inch color touch screen, friendly man-machine interface and easier operation; 4. The selection of different sampling heads can realize the collection of TSP/PM10/PM2.5/fluoride/air heavy metals/SVOC/SVOCs; among them, the air fluoride sampling head and the semi-volatile organic compound sampling head are standard; 5. Adopt imported brushless sampling pump with large flow, high negative pressure and long life (uninterrupted operation time > 20,000 hours), when the flow rate is 50L/min, the load capacity is > 20kPa; 6. Adopt imported sampling pump controller with gas circuit blocking and low flow protection functions; 7. Support USB data export, built-in large-capacity data storage, with instantaneous data storage function; 8. The archive file format has two formats: TXT and CSV; optional printing function module; 9. Adopt high-precision, corrosion-resistant, high-humidity-resistant electronic flowmeter to ensure high reliability and high accuracy of sampling volume; 10. Adopt imported pressure sensor; 11. Automatically measure atmospheric pressure and temperature, and automatically calculate standard volume; 12. The data is automatically protected when the power is cut off during the sampling process, and the sampling will continue after the power is turned on; 13. Timed sampling, interval sampling, and 24-hour continuous sampling are available. Technical parameter: Sampling flow: (50～250)L/min Working power supply: AC (220±22)V, (50±1)Hz Host size: (length 240 × width 270 × height 370) mm Weight of the whole machine: about 7kg Power consumption: <1000W
