Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing laboratories. Designers should be in accordance with the project site soil radon concentration level degree, Jiaozuo pile engineering test center, and with reference to civil engineering category classification, according to the relevant provisions of the "civil engineering indoor environmental pollution control" in, carry out pollution control project design. Civil engineering design, involving indoor radon pollution control design requirements, in accordance with the decision to consider three aspects: First, according to the project site soil radon concentration level degree, and second, referring to the civil engineering category rating, third based on "civil engineering indoor environmental pollution control" in the relevant provisions. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, pile foundation engineering inspection, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects aptitude test and testing laboratories. ① bubble absorber tube. Applicable to the acquisition of gaseous and vaporous substances. Absorption 5 ~ 10mL bottle can be installed to absorb liquid, sample flow is 05 ~ 20L / min. ② shock absorber tube. Suitable aerosol collection. Due to the small inlet pipe nozzle and from near the bottom of the bottle, sampling, sample quickly and soon the impact from the nozzle at the bottom of the aerosol particle can easily be broken, thus particularly susceptible to absorbing liquid to absorb shock absorber tube Not applicable to collect gaseous and vaporous substances. Shock absorber pipe with a small (5 ~ 10mL loaded absorbing liquid sample flow 30L / min) and large (with 50 ~ 100mL absorbing liquid, sample flow is 30L / min) two specifications. ③ perforated sieve absorption tube (bottle). It may be suitable for acquisition of gaseous, vaporous and mist aerosol substances. After absorption of the sample through the tube plate, Changyuan pile engineering test center, is dispersed into small bubbles, and the retention time is long, Mengzhou pile engineering test center, greatly increasing the gas-liquid contact area, thereby enhancing the the absorption efficiency. Absorption 5 ~ 10mL bottle can be installed to absorb liquid, sample flow is 01 ~ 10L / min. Absorption tube with a small (with 10 ~ 30mL absorbing liquid, sample flow is 05 ~ 20L / min) and large (with 50 ~ 100mL absorbing liquid, sample flow is 30L / min) two kinds.
