High Volume Air Sampler "HV-RW" is an outdoor installation and all-weather air sampler that collects hazardous substances in high-volume conditions. There are 2 sampler models, for aerosols and for dioxins. Collapsible design makes it easy to carry and store. With its constant flow rate device, reduction in suction flow rate due to increased dust collection is minimized. Touch-panel is used for the display unit. Used with particle sizer (optional), sampling of 100% removal of over 10μm particles is achieved. [Features] • Noise reduction (compared to HV-F series) • Error log • Leakage check (optional) • Great flow rate correction (20 ℃ 1 atm / 25 ℃ 1 atm / actual flow rate) • Exhaust duct connection * For details, please contact us or download our catalog.
