Timing function: switch time, sniffing identified remind timing, sampling remind sampling time.
Thermostat board size: 0.3 × 0.8m × 2 blocks.
Constant temperature hot plate block uniformity: no two locations of the temperature difference between points is less than 1  .

Instruments construction two parts collection device and control cabniet One collection device using non-adsorbed formaldehyde, VOC air within the stainless steel to produce a size for the long 1000mm, width 1000mm, 300mm high the box
 Body and the geometric center of the top four sides are fitted with a one-way valve diameter ¦ 10mm; the top of the sample connecting gas sampling port, the side of the installation of four-way valve, used to supplement the air. One-way valve in the sampling port next to the hole diameter ¦ 100mm Cover for odor discrimination ( olfactory identified holes) .
All materials for the metal box, no formaldehyde and TVOC release.

Laboratory Environmental Requirements Temperature of 23  ± 5  , into the test chamber air formaldehyde concentration should be less than 0.01mg/ m3, TVOC concentration should be less than 0.06mg/ m3, at the time 24h ( recommended laboratory cross-contamination between samples note) .
