SP208 is used for sampling of chemical substances in the atmosphere to sample tubes
(a glass tube filled up with packing material) or sampling cartridges.

Features

Large flow rate range
1000 type corresponds to the sampling cartridge which suction resistance can be large
different by formaldehyde and VOC by one set.
100 type is very high accuracy in low flow rate range and suitable for thermal desorption.

Correspondence tosuction resistance change
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.

Multiple functions
A setup of sampling start conditions
Sampling start can be selected from the conditions of Real Time (Year, Month, Day, hour, and Min.)
after setting time (minute) progress.

A setup of sampling end conditions
Sampling end can be selected from the lapsed time from a sampling start, the total sampling volume
and the conditions of sequencing (it stops manually).

Sampling conditions are saved at file
Checking functions can be performed by a personal computer. Software is an option.

Adjustment of a pulse to be optimal conditions
A pulse style is detected and (High, Good, or Low) is displayed in the 3 color LED to be
the best condition of pump suction capability and suction resistance of a sample tube
or a trapping cartridge.
When pulse (High, Low) is displayed, adjust a pulse valve to be "Good" manually.

Easy to Operate

･SL Joint
When PTFE tube with SUS piping kit is used, the hose joint will be replaced.

･Filter Joint
The filter can be replaced by customers.
Each joint is connectable.

• The back foot was added to the bottom of the unit.
• SP208II can now be placed on the floor when it is placed while grabbing the handle.
• Detaching the cable is easy since RS232C communication connector is placed in
  the front side of the unit.

Application

• Suitable for sampling (solid phase adsorption / thermal desorption) of VOCs in indoor air measurement.
• Suitable for sampling of building-materials out-gassing with a micro chamber.
• Accuracy guarantee (10-20 mL/min.±10%) in a low flow rate range is offered.

• Suitable for sampling of the formaldehyde in indoor air measurement, and sampling
  (solid phase adsorption / solvent sampling process) of VOCs.
• Suitable also for sampling of SVOC in a habitation residence.
• Suitable for sampling of building-materials out-gassing with a small chamber.
• Suitable for sampling of the ethylene-oxide in the atmosphere and work environment.
