Application
Formaldehyde mattress mattress tester is mainly applied to formaldehyde, VOC emission test.

Technical parameters

Studio dimensions: length × width × height = 1.0 × 1.0 × 0.3 (m) (referring to the internal space dimensions).
Four corners, each with a box intake, a one-way air intake device, pore diameter D = 4mm.
Pump flow range: 0.1 ~ 5L/min.
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 Φ10mm; 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 Φ100mm 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).
