日本GASTEC 甲醛检测管91P
详细介绍
GASTEC为了满足用户在气体检测方面的需要,而开发出了电子自动采气泵。用传统的电子吸气泵几乎不能进行有效的采气,因为检测管里的填充试剂密度很高。而GASTEC开发的GSP电泵系列能提供强劲吸力,能满足特定的检测管的取样要求。电泵和检测管组成的新的检测系统能适用于作业环境的检测。

Possibly coexisting substances and their interferences
Substance(s) | Interference | Colour change by itself |
Ammonia | 2 ppm (or less) | No | No |
Nitrogen dioxide | 1 ppm (or less) | No | No |
Acetaldehyde | "+" error (higher reading) | produces pinkish discolouration | |
Acetone | 0.3 ppm (or less) | No | Produces pinkish stain around tube opening (inlet) |
Ethanol | No | No | |
Ethyl acetate | No | No | |
p-dichlorobenzene | No | No | |
Toluene | No | No | |
Scrubber 1 (black): removes acetone Scrubber 2 (purple): Ammonia and nitrogen dioxide are removed. The presence of ammonia causes the purple scrubber 2 to turn yellow. The presence of nitrogen dioxide causes scrubber 2 to turn a darker shade of purple |
Calibration gas generation | Diffusion tube method (analysis: by absorptiometry, acetylacetone method) |
Miscellaneous
Electric sampling pump This detector tube is suited for measuring formaldehyde in indoor environments. The GSP-200 / GSP-300FT series automatic gas samplers (or comparable sampling devices/pumps) should always be used for optimal performance. A deviation of +/-10% in the sampling flowrate (i.e. amount of air flowing through the tube at a given moment) or the sampling amount (total sampled amount of target substance) causes an average margin of error of approx. +/-10% (maximum +/-20%) in the indicated value. Formaldehyde indoor concentration threshold: 0.08 ppm (mean value during 30 minutes) |
TLV-TWA | TLV-S | Explosive range |
