Product details
Purpose:
Used for collecting environmental air microbial samples, equipped with a six stage sieve impact sampling head as standard; When different sampling heads are selected, they are also suitable for collecting dust, particulate matter, and other samples within the corresponding flow range.
Adopting standards:
GBT 18204.3-2013 "Methods for hygiene inspection of public places (airborne microorganisms)"
HJ 194-2017 Technical Specification for Manual Monitoring of Environmental Air Quality
Main features:
1. Constant current: Using flow, pressure, temperature sensors and microcontroller measurement and control technology, the flow rate of the vacuum pump is automatically controlled to achieve constant flow sampling. The working point flow rate of the six level sieve cutter is 28.3L/min.
2. It has airtightness detection function.
3. Power outage protection: During the sampling process, if there is a power outage, the data can be automatically saved and the sampling can continue after the power is restored.
4. Overload protection: During the sampling process, if the sampling flow deviates from the set flow by more than ± 10% for 5 consecutive minutes, the instrument will automatically shut down for protection.
5. It can automatically measure and display parameters such as ambient temperature, atmospheric pressure, flow rate, sampling volume (standard condition, working condition, reference, sampling time, power outage time), etc.
6. Able to digitally set parameters such as sampling flow rate (operating conditions), sampling time, interval sampling time, sampling volume, etc.
7. Able to digitally calibrate values such as flow rate, temperature, pressure, and time.
8. Data storage and export: It can automatically store 100 pieces of sampling data, which can be viewed, printed, and exported from a USB drive.
9. Mold based production, high reliability, small size, and light weight.
10. The sampler is easy and simple to fix on the triangular bracket (patented technology).
11. This instrument is not suitable for explosion-proof field conditions.

Quantitative sampling: Sampling volume setting range (1~9999 9999.9) L; Immediate sampling: Sampling time setting range (00h01min~99h59min); Timed sampling: Set the starting time range (00:00~23:59) and sampling time range (00h01min~99h59min); Interval sampling: The number of interval sampling times is (1~99), and the sampling time interval and sampling time can be set within 00h1min~23h59min. The sampling start time can be set arbitrarily; 24-hour sampling: Start sampling immediately, with a sampling time of 24 hours. |
