Introduction: It is suitable for the sampling of volatile organic, toxic and harmful gases in ambient air, workplaces, and industrial production. It can be used by environmental protection, health, labor, security, military, scientific research, education and other departments. Executive standard GB/T 17061-1997 "Technical Specification for Air Sampling Instruments in Workplaces" HJ644-2013 "Ambient Air Determination of Volatile Organic Compounds" HJ734-2014 "Determination of Volatile Organic Compounds in Fixed Pollution Source Waste Gas Solid Phase Adsorption Thermal Desorption/Gas Chromatography Mass Spectrometry" Features: 1. Original flow control algorithm, stable small flow 2. Using mass flow sensor, high flow control accuracy 3. Using sampling pump, constant current sampling, good stability 4. Built-in high-energy lithium battery, working for 12 hours on one charge 5. Automatic measurement of atmospheric pressure, temperature, automatic calculation of working condition flow, standard condition flow, reference flow and working condition volume, standard condition volume, reference volume 6. Multiple sampling modes of instant sampling, timing sampling and interval sampling are available 7. With under-voltage and power-down protection function, incoming call continues to sample to ensure that the sampled data is not lost 8.5 micron double dust filter to protect the inside of the sampler from dust, and the sampler has a longer service life 9. Portable, small size, light weight, equipped with a triangular bracket, the sampling height is adjustable 10. One machine with multiple functions, supports multiple sampling methods such as activated carbon adsorption tube, solution absorption bottle, filter membrane, etc. 11. Built-in Bluetooth module, optional mini Bluetooth printer, print sample data
