RAD****0 radon sensor is a radon detector developed and designed by Shengsen Company according to GB*********0 "Indoor Environmental Pollution Control Standard for Civil Building Engineering". It adopts photoelectric transistor sensor technology imported from Europe, with high sensitivity, good consistency and has been calibrated. Simple and easy to use, it is suitable for long-term online measurement and early warning in various fields such as construction, indoor air quality, scientific research, underground exploration, etc.
Measurement principle: phototransistor sensor. Silicon and internal amplifiers for detecting radon daughter particles (bipolar junction transistors).
Technical indicators:
1. Detectable gas: total radon particles in the air.
2, Measuring range: 0.*****0pCi/L(***3,**0Bq/m3)
3, sensitivity: 1.8cph/(pCi/L) or *0Bq/m3.
4, resolution: 1Bq/m3
5, display interface: 4.*-inch touch LCD screen, English and Chinese operation menu.
6, data update: 1 hour after the boot, the data is updated about every *0 minutes.
7, every hour count: minimum: 4cph average: 6cph
8, sensor preheating time: 1 hour
9, Repeatability: *5% (at **0 PCI/L)
*0, measurement accuracy: 6% (*8h at **0bq/m3)
*1. Sampling method: natural diffusion.
*2, temperature measurement: **0℃ ~ *0℃, humidity measurement: ****0%RH.
*3, storage function: built-in ****0 sets of data storage.
*4, service life: more than 5 years
*5, environmental conditions: ***0℃, ****0%RH.
*6, Power supply: built-in lithium battery, Type-C charging port.
*7, signal output: RS**2
*8, analysis software: with upper computer analysis software.
*9, print output: optional printer can achieve on-site printing.
*0. Overall size: **0mmX**0mmX*0mm, without protruding part.
*1, optional: pressure measurement, micro printer, universal tripod, 4G wireless transmission, carbon monoxide measurement, carbon dioxide measurement function.
*2, Configuration: measuring host, PC analysis software, Type-C charging cable, RS**2 serial cable, portable box.
Note: The sensor should not be exposed to bright light! This can have a negative effect on the measurement results. The temperature of the sensor must be kept within the range of ***0 ° C during measurement.
Warning: High voltage will be generated inside the sensor. Although the high-pressure area is isolated and protected by the housing, the contact area between the measurement chamber and the motherboard surface
This domain may be exposed to high pressure. Hold the sensor carefully!
Measurement recommendations:
The sensor provides radon concentration levels every hour. Therefore, the first valid data can be obtained after 1 hour of power-on.
Because radon is highly variable over a short period of time, radon concentration data can be affected by serious changes. Therefore, in order to obtain more accurate data, it is recommended to use the average value. Average values are more indicative of the actual presence of radon than instantaneous values. For short-term analyses, it is recommended to use at least the average of continuous measurements over *2 hours. For long-term analysis, it is recommended to calculate the average over a period of **7 days or more and measure it at least quarterly.
Test result judgment:
The measurement results are expressed in Beckel and expressed as beckel per cubic meter of air (Bq/m3).
Outdoor radon concentrations average about 4Bq/m3. The average household radon concentration is *0Bq/m3. For concentrations below **0Bq/m3, the individual risk remains relatively low. However, as radon concentrations increase, so does the risk. There is no known "safe" concentration of radon, but the lower the concentration you are exposed to, the lower the risk to your health.
