Pm 2.5 Air Sampler

We are a skilled maker of the user-friendly Pm 2.5 Air Sampler. The controller, which is microprocessor-based, aids in maintaining a steady air sampling rate. The micro-controller-based data logger also logs the air temperature, filter pressure, and barometric pressure. A smart report of the system parameters is also provided by the PC-based programme.

Pm 2.5 Air Sampler advanced feature is:

A microprocessor-based electronic flow controller maintains the sampling rate at 1 m3/hr while automatically adjusting for an increase in pressure drop caused by dust buildup on the filter.

A USB Flash memory-based data logger incorporated inside the APM 550 EL records Filter ID, air temperature, filter temperature, barometric pressure, flow rate, coefficient of variation (CV), and other data.

Specifications:

Size-selective inlets for PM 10 and WINS Impactor for PM 2.5 meet USEPA design requirements.

1 m3/hr of flow is maintained by an electronic controller with a microprocessor.

If the flow rate falls more than 10% below the 16.7 LPM specified threshold, the sampler will automatically shut off.

Oil-free, non-pulsing vacuum pump with an induction motor for steady flow rate

Nominal 220 V, single phase, 50 Hz AC mains supply is the required power.

A solid ground connection is necessary for efficient operation and safety.

Automated Sampling: Built-in technology to regulate sampler start and stop times

The system automatically adjusts the volumetric flow rate utilising sensors for the ambient temperature, barometric pressure, and filter pressure.

Real-time clock based elapsed time indicator. Every sample's operating time is documented in hours and minutes.

Flow recorder: A USB flash memory-based system that records flow rate, the amount of sampled air, the temperature of the air, the temperature of the filter, the pressure of the filter, and the barometric pressure.

The MCU unit totalizes and displays the amount of air that was sampled.

Display: A large, 40-channel, four-line LCD with backlighting shows all system parameters at a glance.

Software and reporting: PC-based software offers an intelligent report of every system parameter that was captured.

At the conclusion of the sample period, run time parameters are summarised.
