Formaldehyde climate box sampling device

Abstract

The invention discloses a formaldehyde climate box sampling device, and relates to the technical field of sampling detection. The formaldehyde climate box sampling device comprises a climate box, a sampling bottle bottom plate, a sampling bottle fixing clamp and a water bath heating container, wherein the sampling bottle bottom plate is fixed to one side of the climate box, the sampling bottle fixing clamp is arranged on the portion, which is on the upper side of the sampling bottle bottom plate, of the climate box, a water bath is formed in the climate box, a heating mechanism is arranged in the water bath, the water bath heating container is placed on the upper side of the heating mechanism, and the climate box is further provided with a light-proof storage mechanism for placing a sampling bottle. The sampling bottle fixing clamp is arranged on the upper side of the sampling bottle bottom plate, the sampling bottle is fixed through the sampling bottle fixing clamp, the sampling bottle is prevented from falling down in the sampling process, and the sampling bottle, the drying tower and the sampling pump are placed on the sampling bottle bottom plate. The water bath heating container and the light-proof storage mechanism are arranged on the climate box, and the formaldehyde solution in the sampling bottle is subjected to water bath heating, light-proof treatment and the like at the climate box, so that the device is more convenient.

Description

technical field [0001] The invention relates to the technical field of sampling and detection, in particular to a formaldehyde climate chamber sampling device. Background technique [0002] The formaldehyde test of the climate chamber method is to put a sample with a surface area of ​​1㎡ into a climate chamber whose temperature, relative humidity, air flow rate and air replacement rate are controlled at a certain value. formaldehyde Released from the sample, mixed with the air in the box, regularly extract the air in the box, pass the extracted air through the absorption bottle filled with distilled water, all the formaldehyde in the air is dissolved in the water; measure the amount of formaldehyde in the absorption liquid and the extracted air Volume, calculate the amount of formaldehyde in each cubic meter of air, in milligrams per cubic meter (mg / m 3 )express. [0003] The side of the existing climate box is provided with a bottom plate for placing the absorption bottle...
