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. This instrument is specifically designed by our company to meet the requirements of GB50325-2010, offering an intelligent solution for monitoring indoor air quality. It is capable of collecting harmful gases such as formaldehyde, ammonia, benzene, TVOC, SO2, and NOx using either liquid absorption or activated carbon tube methods. Additionally, it can function as a smoke sampler, making it an essential tool for environmental monitoring, construction quality control, and public health departments. The device features dual constant flow sampling, ensuring high stability and accuracy even under heavy loads like when using adsorption tubes or activated carbon samplers.
III. Key Performance Features:
1. Equipped with an imported digital flow sensor, this instrument allows for precise setting of instantaneous flow and provides digital display. It supports dual constant current sampling, automatically maintaining the set flow rate for accurate sample collection.
2. The user-friendly design includes a fast timing sampling function, compact size, and portability. It automatically saves sampling data, remembers previous settings, and enables one-click sampling for convenience.
3. A unique three-in-one design combines drying, filtering, and anti-back suction functions in one unit. This effectively removes moisture, filters dust, and prevents backflow, ensuring stable performance without frequent maintenance.
4. Optional heater and HW-2 intelligent incubator allow for constant temperature and current sampling in low-temperature environments, enhancing versatility.
5. The sampling pump is driven by an imported DC brushless motor, featuring a stainless steel body that delivers high suction power, stable flow, and over 10,000 hours of continuous operation.
6. It automatically detects pressure and temperature before sampling, calculates and displays both actual and standard sampling volumes for improved accuracy.
7. An imported wide-temperature OLED screen ensures visibility in extreme cold and low-light conditions, with a Chinese menu interface for easy navigation.
8. Users can calibrate instrument parameters via the keyboard, with password protection to ensure data security and prevent unauthorized modifications. It also offers automatic factory reset.
9. The device displays real-time clock, dual sampling time, date, flow, and pressure, with the ability to store up to 1,000 groups of data.
10. Powered by AC/DC with a built-in large-capacity battery, it supports continuous operation for more than 8 hours, ideal for field use.
