easySPT100eco

This is an impactor using of Hirst Type compliant with EN16868:2019 and is certified in capture efficiecy.

The suction flow is electronically controlled and can be adjust from 5l/m up 15 l/m, and is maintained constant by using an internal flow meter that continuosly measure suction flow and adjust it. The accurancy of the measure is around 0.5 l/m.

It’s a centrifugal pump with an high efficency motor. The impeller is designet for the maximum head and minimum air resistance. The result is a pump with low energy consumpiton allowing a long battery life.

The instrument can be supplied only with mains. Is provided an external power supply to connect instrument to mains.

easySPT100 is based on Hirt type sampling method. Particles of defined size, typically 10/100um, enter the nozzle with a predefined speed due to the suction flow and accelerate due to the restriction of the nozzle size. The acceleration depend from size and weight of particles. For this reason at the end of the nozzle some particles will continue their run straight, some others will follow air flow. Particles that will run straight will impact the treated strip and will remain trapped on it. For this reason this type of instrument are also called impactor. The treated strip is fixed on a drum that can completely rotate in one day or in 7 days (depend on which type of head you buy)

The instrument is equipped with some electronics parts and an hight efficiency pump with a limited life. For these reasons some tricks must be consider to avoid a rapid degradation of some parts. The presence of water inside, even if possible in little quantity, must be avoided as much as possible. Also sealing o-rings must be checked to avoid that water enter the instrument. The inside pump have a medium life of at least 6000/8000 hours, after the efficiency of the instrument decrease rapidly (capture efficiency ). For this reason is important to take in consideration the hours of use and prevent the pump problems. Like for easySPT200 the nozzle must be maintained cleaned as much as possible.
