Exhaust silencer filter ASSY for SP209-100Dual (Identification No. 3)

SP209 can perform two (2) lines sampling at once by two (2) pumps and two (2) mass flow controllers. It also can perform integration of suction and its volume.

There are 2 versions availabe: SP209-100Dual and SP209-1000Dual.
1000 type corresponds to the sampling cartridge which suction resistance can be large different by formaldehyde and VOC by one set (20-1000 mL/min).
100 type is very high accuracy in low flow rate range and suitable for thermal desorption (2-100 mL/min).

The suction capability of pumps is adjusted to be able to perform sampling at stable flow rate since it has a function that setting flow rate is maintained even if suction resistance of trapping materials or cartridge is changed. Especially when sampling is performed in a low flow rate range, the pump`s revolution speed is getting slower, and noise or consumption power can be down.
