Aerosols absorb water and swell during humid environments. This results in larger signals that are interpreted as increased aerosol concentration by a photometer. This elevated measurement caused by humidity is reduced by the Heated Inlet Sample Conditioner.

TSI Instruments have designed this product to install over the AutoZero module on DustTrak II/DRX Models 8530, 8530EP, 8533 and 8533EP while in use with Environmental Enclosure Models 8535 or 8537. A wiring harness (included with the conditioner) easily connects power to the conditioner and the DustTrak from either the external battery system or line voltage.
