The intelligent constant current IAQ Pro air sampling pump from SENSIDYNE company in the United States has unique constant current technology, which improves the stability of constant current in low flow range. It can withstand resistance up to 30 "H2O (0~7.47kPa) with an error of no more than 5%. Can be used in conjunction with adsorption bottles and various sampling media. Widely applicable to different sampling scenarios such as indoor environmental testing, occupational health, atmospheric sampling, scientific research, etc.
According to the national indoor air quality standard IAQ STANDARD GB/T18883-2002, the quality assurance requirements for air sampling are: "The sampling system flow rate should be able to remain constant, and the intake flow rate of the sampling system should be calibrated with a primary soap film meter before and after sampling, with an error not exceeding 5%Soap film meterCompare the scale of the sampler flowmeter, calibrate 5 points, and draw a flow standard curve. Record the atmospheric pressure and temperature during calibration
characteristic:
1.Constant current sampling, automatically compensates for flow loss within the maximum withstand voltage range, and controls the error value within 5% of the set value.
2.When the traffic exceeds the original set value by 5% or the battery is low, the alarm light will light up and automatically stop after 45 seconds to prevent erroneous sampling.
3.Programmable: Set sampling time, pause time, delayed startup time, and sampling frequency.
4.Flow range: constant flow, low flow range: 50~600ml/min.
5.Rechargeable battery. Safe back pressure can operate continuously for 8 hours without errors.
