Smoke test tubes contain a brown-orange material impregnated with smoke sulfuric acid. When air is pumped through the tube, with the help of a rubber blower, an aerosol of sulfuric acid in the form of white smoke comes out. The density of the smoke generated by sulfuric acid increases with increasing atmospheric humidity. The smoke would
For the transport of the sampled filters to the laboratories, as indicated in the method UNICHIM 285-2003, you must “Use suitable containers to prevent damage during the trip. It is preferable to use anti-static material containers and equipped with contoured cover, to ensure the locking of the circumference of the filter where the dust is not deposited”. To meet
NIOSH, OSHA and EPA rules involve use of adsorbent tubes for “active” sampling of many toxic chemicals present in the atmosphere or in the duct flows as gases and vapors. From the quantity of captured substance, and determined analytically, it is possible, knowing the total volume of aspirated air, to determinate the concentration present in the
Velometer is a highly reliable and handy instrument realized for the control of temperature variations and ΔP in conveyed flows, to calculate their speed. Coupled with all kinds of our probes, Velometer gives an instantaneous reading of the pressure difference via a needle transducer and displays the flow temperature through a high precision display.Iit
PROBE FOR DUST SAMPLING Simple monotube probe (AISI 316 steel or titanium) complete with sliding tube, basket/filter holders adapter for the use of membranes Ø 47 mm and flange 90 mm dimeter. Length 1 m. Isokinetic composite probe (AISI 316 steel or titanium), with flange diameter 90 mm. This model, which includes both the sample probe and the Darcy tube and
The components of the probe in contact with the polluted are made entirely of titanium and the measurement of the sample temperature, as required by UNI EN 1948 occurs within the sampling chamber downstream the filter media. The probe, protected by utility model, through a particular removable insert positioned within the sampling chamber, allows the operator to interchange the sampling media
Dehumidifier cylinder (diam. 9 cm – h. 23 cm). It is a solid Plexiglas cartridge loadable with common silica gel with indicator dye or with activated carbon, suitable to hold any condense whose content could be corrosive and therefore may damage the pump in case of accidental aspiration (Code A.3042) Silica gel with turning yellow-green indicator
Cooler case complete of stainless steel AISI 316 basket for n° 4 impingers. This solution allows to maintain the reagents in the impingers at a low temperature extending efficiency performance. The cooling can be done via pats of ice or by filling with cold water and ice (Code A.3055) Portable cooler box with
Membrane holder device for inhalable fraction Stainless steel/aluminium membrane holder equipped with anodized aluminium “open cylinder” for airborne fibres monitoring, suitable for housing a tripod and hose connector, ø 12 mm ¼”. The holders are compatible with 25mm diameter filters (code A.2000) and with 47mm diameter filters (code A.2006) Stainless steel/aluminium membrane holder, “Double Cone”
Acetone vaporizer is tipycally used for asbestos sampling and quantification, as it is necessary to bleach the filters for counting asbestos fibers with a microscope. Its compactness and portability allow using the instrument both in laboratory and on the field without using hoods. The process of diaphanization is very rapid: only 2 minutes to reach
