The DustTrak Environmental Enclosure 8535 is a weatherproof case that protects DustTrak II and DRX Aerosol Monitor Models 8530, 8530EP, 8533, and 8533EP, allowing for accurate and precise measurements in harsh environments. It is suitable for a wide range of applications, such as outdoor environmental monitoring, community air monitoring plans (CAMP), fugitive emissions monitoring, site perimeter monitoring, dust control operations, and urban pollution studies. The enclosure includes a 360° omni-directional sampling inlet designed to sample efficiently in a broad range of wind conditions, a water trap bottle that prevents precipitation from entering the instrument, and a secure method of deploying the DustTrak aerosol monitor and its accessories. Optional accessories such as an internal battery system, heat shield, solar power system, Cloud Data Management System, and heated inlet sample conditioner are available. The enclosure can be mounted to a standard survey tripod equipped with a 5/8″-11 threaded stud, making it field portable. The DustTrak Environmental Enclosure 8535 is also on the South Coast AQMD pre-approved list of instruments for Rule 1466.
