Model 928 Canister Sampler

The Model 928 is an innovative ambient air VOCs sampler with versatile functionality. It can be used as a portable, time-integrated sampler for routine ambient air collection with canisters, allowing samples to be transported to the laboratory for VOC analysis. For environments with high VOC concentrations, direct sampling can contaminate the canister, making it difficult to clean and potentially unusable for future sampling. To prevent this, the Model 928 features a dilution function that dilutes the sample gas at a set ratio before it enters the canister, ensuring the long-term reliability and cleanliness of your sampling canisters.

Features

● Performs time-integrated sampling of volatile organic compounds (VOCs) in ambient air.

● Utilizes advanced electronic pressure control technology for precise control over sampling and dilution flow rates.

● Features a sample dilution function, capable of diluting samples by a factor of 1 to 187.

● Offers three distinct stop-pressure sampling modes: sub-atmospheric, at atmospheric pressure, and above atmospheric pressure (in dilution sampling scenarios).

● All internal tubing and fittings are Siltek-treated to guarantee cleanliness and sample integrity.

● Battery-powered, with a single charge providing up to 12 hours of continuous operation.

● Compact and portable design, complete with a convenient carrying case.
