Ontech821 Automatic sampler

1. Box design,  with folding handle, easy to carry;

2. Host standard touch screen, parameter display, touch control, historical data query functions; standard MFC flow control;

3.Use intelligence: support automatic leak detection before sampling, sequence sampling, timing sampling, trigger sampling, remote start sampling and other sampling modes;

4.Optional sensors can be used to record the temperature and humidity changes of the sampling environment, SUMMA canister leakage alarm function, pressure abnormal alarm function, aldehyde and ketone tube sampling function;

5.Controlled start and stop, wide range flow adjustment; without hardware replacement,  can realize instantaneous sampling and constant current sampling switching between 1 hour to 24 hours;

6.One-key quality control function: sampling canister pressure detection, pressure judgment, flow calibration, flow recording and other functions;

7.Double canister, four canister optional, support parallel sampling; with waterproof, dustproof function, suitable for outdoor use;

8.The sampler flow path is inert by molten silicon to reduce adsorption.

1. Sampling method: vacuum box air bag or SUMMA canister; 

2. Environmental humidity: ≤85%;

3. Environmental temperature: (-20~50) ℃;

4. Solenoid valve: 316 stainless steel material;

5. Display mode: touch the display screen;

Ontech821 Automatic sampler is a portable mobile SUMMA canister automatic sampling equipment, intelligent control time and constant flow sampling, truly restore the ambient air at sampling point, not only has all the functions of the traditional SUMMA canister automatic sampling equipment, but also has the characteristics of small size and easy to carry, adapt to the emergency sampling of various places, flexible sampling in small space.

Ontech821 Remote control VOCs sampling system can be equipped with meteorological five parameters, noise, light scattering method PM10, PM2.5 sensor, PID sensor, video sensor and other equipment.
