TSI 801851 Heated Inlet Sample Conditioner without Autozero Module

The TSI 801851 Heated Inlet Sample Conditioner conditions the sample air stream before entering the DustTrak™ II or DustTrak DRX optics. In humid environments, aerosols absorb water and swell, resulting in larger signals which a photometer interprets as increased aerosol concentration. Sample conditioning removes humidity and water vapour from the sample, reducing elevated measurements caused by humidity. The 801851 is designed to install over the TSI 801690 AutoZero Module (not included) on the DustTrak while in use with Environmental Enclosure 8535.
