AirChek2000's patented built-in flow sensor allows for electronic flow control of air sampling. This unique technology enables users to use a three key keyboard or install a DataTrac? Using a PC with 2000 software to program the expected flow rate, the accuracy can reach ± 5%; No other tools are needed. This built-in airflow sensor directly measures the flow rate and maintains the set flow rate as a secondary reference. Users can automatically calibrate the flow rate through an external primary reference (see CalChek original article on page 10). After startup, the built-in sensor immediately reaches the set flow rate and can automatically adjust changes caused by different temperatures and atmospheric pressures. A single charge of the battery pack can ensure that AirChek2000 samples for more than 8 hours.
The AirChek2000 sampling pump has two simple programming options to meet user sampling needs.
① Manual three key programming
The three keys are located on the surface of the pump. Set sampling time, flow rate, and other information such as calibration and sampling through simple keyboard operations. No other accessories are needed to adjust the flow rate. Password protection settings prevent changes in settings due to accidental factors and maintain effective sampling. Once the button is pressed, the corresponding sampling parameters are immediately displayed on the LCD screen.
② PC programming
Provide the best air sampling program, using a computer and DataTrac2000 software, to maximize the sampling function of the AirChek2000 sampling pump: establish a complete operating sequence, download data to the PC, generate exposure and calibration data reports.
