IIpurpose

The solution absorption method is used to collect harmful gases from flue pollution sources, and high-tech technologies such as computers, sensors, and automatic control are used 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 sampling volume can be automatically accumulated. It can be widely used in departments such as environmental monitoring, labor protection, industrial hygiene, factories and mining enterprises for sampling harmful gases in pipeline pollution sources.

3、 Performance characteristics

1. Mold forming process, beautiful appearance, light weight, and small volume.

2. Adopting imported precision electronic sensors with filters, it automatically controls the sampling flow rate according to the set value for constant current sampling. Ensure measurement accuracy, no positional impact, and significantly superior performance to rotameters.

3. The rotary vane pump made of imported DC brushless motor is used as the sampling power, with automatic lubrication, all stainless steel pump body, high suction negative pressure, stable flow rate, and a fault free operation time of more than 10000 hours.

4 Silencing, achieving subwoofer operation.

5. Automatic detection of pressure and temperature in front of the flowmeter, automatic calculation and display of sampling volume and standard volume, and automatic fault protection function.

6. Automatic zero 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 the instrument data.

7. Real-time clock, direct display of sampling time, date, flow, pressure, etc., data storage 1000 groups.

8. Adopting imported wide temperature OLED display screen, suitable for working in ultra-low temperature and low illumination environments. Chinese menu display, illustrated and easy to operate.

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 display of temperature, and a titanium metal filter element to ensure measurement accuracy.

11. The unique drying cylinder with a combination of drying, filtering, and anti backsuction design can    Dry moisture, filter dust, and reduce the impact on flow rate by emptying and suction, achieving long-term operation without cleaning.

12. Automatic memory setting for sampling data, prioritized for next boot up, achieving one click sampling.

13. The color recognition function of the air circuit facilitates users to quickly and accurately connect pipelines. The sampling bottle has a left and right design, which avoids misoperation and is convenient

Air circuit connection. The tripod cloud desktop design is easy to operate.

14. The instrument is equipped with rechargeable batteries for saving data in case of AC power outage, automatically recovering sampling in case of AC power call, automatically deducting the power outage time during the sampling process, and allowing users to check the power outage time.
