Canister Sampling System 1900A, 2 Channels Expandable To 9 Or 32 (CAT#: STEM-AL-9735-ZJF)

The 1900A is an automatic canister sampling system for programmed collection of multiple ambient-air canister samples. The sampler is designed for field and remote collection of multiple air samples into canisters. A two-channel standard configuration can be expanded to nine or thirty-two channels. Sampling can be programmed locally, remotely, or started by an external trigger. The system records sampling time, canister pressure, and flow-history curves. A digital pressure controller provides full-range flow adjustment without replacing mechanical restrictors. An inert high-capacity filter removes particles and aerosols before the sample enters the canister. Temperature compensation is used to support constant-flow sampling under changing field conditions.
