Frequently Asked Questions
Q
What particulate matter sizes can this sampler collect?
The sampler is specially designed for PM2.5 and PM10 particulate matter collection. The dedicated sampling head is made of anti-static aluminum alloy, which prevents particles from adhering to the surface and ensures accurate, targeted capture of both fine and coarse atmospheric particulates with minimal contamination or sampling loss.
Q
How does the automatic flow control system maintain sampling accuracy?
An electronic flowmeter integrated with a microcomputer monitors the sampling flow in real time at a target rate of 16.67 L/min. When fluctuations arise due to voltage instability, increasing filter resistance, or ambient temperature changes, the system automatically adjusts pump output to compensate—maintaining flow accuracy within ±2% throughout the entire sampling session.
Q
What happens to sampling data if a power outage occurs mid-session?
The instrument features built-in power-off protection. All working data and progress are automatically saved the moment power is interrupted. Once power is restored, the device automatically resumes sampling from the exact point of interruption—ensuring there are no gaps or losses in the collected data record.
Q
Can this sampler be used outdoors or in remote field locations without a stable power supply?
Yes. The sampler supports dual power supply modes—standard AC power and a built-in lithium battery with a cycle life of ≥1,000 charges (DC 29.4V 2A charger). Combined with its weather-resistant modular design that offers reliable rain and snow protection, the device is well-suited for long-term outdoor monitoring and off-grid field deployments in harsh environments.
Q
What sampling modes are available, and which is best for long-term continuous monitoring?
The sampler supports three modes: instant sampling for on-demand spot checks, scheduled sampling triggered at a predefined date and time, and periodic sampling that repeats automatically at set intervals. For long-term continuous environmental monitoring, periodic sampling mode is recommended, as it fully automates the collection cycle without requiring manual intervention between sessions.
Q
What safety mechanisms ensure the validity of collected sampling data?
The instrument includes a flow anomaly protection feature: if the sampling flow deviates from the preset value by more than ±10% for more than 60 consecutive seconds, the device automatically halts sampling and records a fault event in the log. This safeguard prevents unreliable data from being stored, ensuring that every recorded sample was collected under verified and stable operating conditions.
