2.Sampling flow error: ≤3%FS
3.Sampling flow stability: The sampling flow stability of the sampler within 8 hours is ≤3.0%FS
4.Load capacity: ≥1000Pa
5.Continuous working time: ≥8h
6.Working noise: ≤65dB (A)
7.Flow meter accuracy: not less than level 2.5
8.Sampling time error: ≤0.1% within 5 minutes
9.Average flow rate at sampling port: 0.5~4.0m/s
10.Air tightness: The sampling head and flow meter of the sampler are kept under a pressure difference of (1000-1100) Pa for 1 minute, and the pressure change shall not exceed 100 Pa.
11.Sampling accuracy error: ≤10%
12.Explosion-proof type: Mining intrinsically safe type ExibI (150°C), suitable for flammable and explosive workplaces and underground sampling in coal mines.
13.Sampling efficiency: in line with the "BMRC" sampling efficiency curve;
14.Dimensions: 120×80×42 (mm)
15.Weight: 450g
The RS485 Tube Soil Temperature and Humidity is a layered soil moisture determination device that uses frequency domain reflectance (FDR) technology to measure the moisture and salt content of the soil. This technology determines the dielectric constant of the soil by analyzing the frequency change...
Soil moisture meter is the most suitable equipment for soil moisture monitoring, which is a scientific instrument specialized in measuring soil moisture. It mainly uses sensors to collect soil moisture in real time and transmit the data to the background, and then analyzes and calculates the corresp...
Soil moisture, that is, the degree of wetness of soil, is very important for agricultural irrigation, environmental protection and disaster prevention. By establishing the Automatic Soil Monitoring System, we can more accurately understand the changes in soil moisture, so that we can more effectivel...
Shipborne automatic weather station is a kind of meteorological observation system using ship as a working platform, which is capable of real-time observation of elements of marine meteorology such as temperature, air pressure, humidity, wind speed, wind direction, rainfall and visibility. In the fi...
