Intelligent constant current atmospheric sampler / constant current atmospheric sampler
I. Implementation of the standard JJG956-2000 "Atmospheric Sampler" and GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering"
II. Instrument Application
This instrument is specifically developed by our company to meet the requirements of GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering." It is an intelligent device designed for the collection and analysis of harmful gases such as formaldehyde, ammonia, benzene, TVOC, SOâ‚‚, NOâ‚“, and others in both ambient and indoor environments. It can also function as a smoke sampler. With its high accuracy and stable performance, it is widely used by environmental monitoring agencies, construction quality inspection departments, and health and epidemic prevention units for reliable gas sampling.
The instrument features dual constant flow sampling, ensuring accurate flow control even under heavy loads like adsorption tubes or activated carbon samplers. This makes it highly suitable for long-term and precise field operations.
III. Key Performance Features
1. The instrument uses an imported digital flow sensor, allowing for precise flow setting and digital display. It supports dual constant current sampling, automatically maintaining the set flow rate for high measurement accuracy and reliable sampling volume.
2. The user-friendly interface offers fast timing sampling, compact design, and portability. It automatically saves sampling data and resumes the previous settings upon startup, enabling one-click sampling.
3. A unique three-in-one design combines drying, filtering, and anti-backsuction functions. This effectively removes moisture, filters dust, and prevents backflow, reducing interference and allowing extended operation without frequent maintenance.
4. Optional heater and HW-2 intelligent incubator options enable constant temperature and constant current sampling in low-temperature environments, enhancing versatility.
5. The rotary vane pump, powered by an imported DC brushless motor, provides strong suction power, stable flow, and over 10,000 hours of maintenance-free operation.
6. It automatically detects pressure and temperature before the flowmeter, calculates and displays the sampling volume and standard volume for accurate results.
7. An imported wide-temperature OLED screen ensures visibility in ultra-low temperatures and low-light conditions, with a Chinese menu for easy navigation and operation.
8. Users can calibrate instrument parameters via the keyboard, with password protection to prevent unauthorized modifications. It also allows automatic restoration to factory settings for data security.
9. The instrument displays real-time clock, dual sampling time, date, flow, and pressure. It can store up to 1,000 sets of data for future reference.
10. Powered by AC or DC, it features a built-in large-capacity battery, providing continuous operation for more than 8 hours, making it ideal for field use.
With these advanced features, this instrument is a reliable and efficient solution for environmental monitoring and indoor air quality testing.
