1、 Execution standards
GB/T16157-1996 "Determination of particles and sampling methods for gaseous pollutants in exhaust from stationary sources"
HJ/T47-1999 Technical Conditions for Smoke Samplers
2、 Purpose:
The solution absorption method is used to collect harmful gases from flue gas pollution sources. High tech technologies such as computers, sensors, and automatic control are adopted to greatly improve measurement accuracy. The temperature and pressure in front of the flowmeter can be detected in real time, and the sampling volume and standard condition sampling volume can be automatically accumulated. It can be widely used in environmental monitoring, labor protection, industrial hygiene, factories and mines to sample harmful gases from pipeline pollution sources.
3、 Performance characteristics
1. Mold forming process, beautiful appearance, light weight, and small volume.
2. Adopting imported precision electronic sensors, the sampling flow rate is automatically controlled to sample at a constant current according to the set value, ensuring measurement accuracy without position influence, and the performance is significantly better than that of a rotor flowmeter.
3. Imported DC sampling pump is used as the sampling power, with high suction negative pressure, stable flow rate, and a fault free operation time of more than 20000 hours.
4. Unique muffler for ultra-low frequency operation.
5. Automatic detection of pressure and temperature in front of the flowmeter, automatic calculation and display of sampling volume and standard condition volume, and automatic fault protection function.
6. Automatic zero point correction, software parameter calibration, ensuring measurement accuracy. Users can calibrate various parameters of the instrument through the keyboard, but they need to enter with a password to ensure the security of instrument data.
7. Real time clock, sampling time, date, flow rate, pressure, etc. are directly displayed, and 1000 sets of data are stored.
8. Adopting imported wide temperature OLED display screen, suitable for working in ultra-low temperature and low light environments, with Chinese menu display, illustrated text, and convenient operation.
9. There are multiple sampling methods available for customers to choose from, including timed sampling, interval sampling, multiple sampling, and cyclic sampling.
10. The instrument is equipped with a heated sampling tube, digital temperature display, and a titanium metal filter element to ensure measurement accuracy.
11. The unique three in one design of drying, filtering, and anti backflow suction in the drying cylinder can efficiently dry moisture, filter dust, and reduce the impact of backflow suction on flow rate, achieving long-term operation without cleaning.
12. The built-in large capacity lithium battery can sample in the absence of AC power, and the sampling data is automatically memorized and set. It is preferred for the next power on, achieving one click sampling.
13. It has power outage protection function, which saves data during AC power outage, automatically restores sampling during AC incoming call, deducts the power outage time during the sampling process, and allows users to query the power outage time.
